DT300 Dual Transmitters are designed for high-density mounting on T-type DIN

rails. Units may be mounted side-by-side on 0.7-inch (17.5mm) centers and support

6-32V DC power via terminals on the unit, or optionally via power wired to a DIN-

rail bus connector. Each channel isolates a wide range of current or voltage input

signals depending on model and can mate with grounded or non-grounded sensors.

Units drive isolated outputs that source current or voltage at each output channel

with support for 0-20mA, 4-20mA, or ±10V, ±5V, 0-10V, and 0-5V output ranges.

Mechanical Dimensions

Units may be mounted to 35mm

“T” type DIN rail (35mm, type

EN50022), providing two isolated

I/O channels on 0.7-inch centers.

WARNING: IEC Safety Standards

may require that this device be

mounted within an approved

metal enclosure or sub-system,

particularly for applications with

exposure to voltages greater than

or equal to 75VDC or 50VAC.

DIN Rail Mounting & Removal

NOTE: It is recommended that this

unit be mounted upright on a DIN

rail allowing free air flow intake

from the bottom vent to flow

through the unit and out the top

vent. This will allow the unit to

run cooler, perform better, and

help to extend the life of the

electronics.

Refer to the following figure for attaching and removing a unit from the DIN rail. A

spring-loaded DIN clip is located on the input side bottom. The opposite rounded

edge at the bottom of the output side allows you to tilt the unit upward to lift it

from the rail while prying the spring clip back with a screwdriver. To attach the

module to T-type DIN rail, angle the top of the unit towards the rail and place the

top groove of the module over the upper lip of the DIN rail. Firmly push the unit

downward towards the rail until it snaps into place. To remove it from the DIN rail,

first separate the input terminal blocks from the bottom side of the module to

create a clearance to the DIN mounting area. You can use a screwdriver to pry the

pluggable terminals out of their sockets. Next, while holding the module in place

from above, insert a screwdriver into the lower path of the bottom of the module to

the DIN rail clip and use it as a lever to force the DIN rail spring clip down while

pulling the bottom of the module outward until it disengages from the rail. Then

simply lift it from the rail.

ELECTRICAL CONNECTIONS

WARNING –EXPLOSION HAZARD –Do not disconnect equipment unless power has

been removed or the area is known to be non-hazardous.

WARNING –EXPLOSION HAZARD –Substitution of any components may impair

suitability for Class I, Division 2.

WARNING –EXPLOSION HAZARD –The area must be known to be non-hazardous

before servicing/replacing the unit and before installing.

Wire terminals may accommodate 14–28 AWG (2.08–0.081mm2) solid or stranded

wire with a minimum temperature rating of 90oC. Input wiring may be shielded or

unshielded type. Ideally, output wires should be twisted pair, or shielded twisted

pair. Use insulated wire to keep channels isolated. Terminals are pluggable and can

be removed from their sockets by prying outward from the top with a flat-head

screwdriver blade. Input channels each have two input paths that support different

nominal ranges (for example, DT336 allows current input to be wired to TB1-1/TB3-

1, and voltage input wired to TB1-3/TB3-3). Strip back wire insulation 0.25-inch on

each lead and insert the wire ends into the cage clamp connector of the terminal

block. Use a screwdriver to tighten the screw by turning it in a clockwise direction

to secure the wire (0.5-0.6 Nm torque). Use adequate wire insulation and follow

proper wiring practice, as common mode voltages can exist on signal wiring.

Generally, output wires are separated from input wires for safety, but this is equally

important for low noise pickup.

Input Connections

Each channel has two input paths, A and B, that support different nominal input

signal ranges. Sensor wires connect directly to transmitter input terminals at TB1

(channel 1) and TB3 (channel 2) at the bottom of the module (the spring-loaded DIN

clip side, as shown in the connection drawing below). Observe proper polarity

when making input connections and make sure that you connect your signal to the

correct input terminal (input return is the middle terminal).

•Unit has three operating modes: You may operate this unit as a dual

transmitter, a single transmitter, or a CH1 signal splitter.

•Dual Transmitter inputs at TB1 (channel 1) and TB3 (channel 2) are isolated

from each other and from their respective outputs at TB4 (channel 1) and TB6

(channel 2), and from power at TB5.Each output has separate terminals for

driving current or voltage which share an output return.

•Inputs are polarized ±, observe proper polarity. The outside terminals of TB1

and TB3 are positive inputs A & B and labeled “+”. The common return for

input paths A & B is the middle terminal of the terminal block. See connection

figure below per input model.

•DT336 ±20mA DC Current is wired to the leftmost terminal of TB1/TB3 and

±0.5VDC is wired to the rightmost terminal of TB1/TB3. The return for these

signal paths is the middle terminal of TB1/TB3.

•DT337 ±1V DC maximum is wired to the leftmost terminal of TB1/TB3 and

±10V DC maximum is wired to the rightmost terminal of TB1/TB3.The return

for these signal paths is the middle terminal of TB1/TB3.

•DT338 ±15V DC maximum is wired to leftmost terminal of TB1/TB3 and ±150V

Battery Sources DC maximum is wired to the rightmost terminal of TB1/TB3.

The return for these signal paths is the middle terminal of TB1/TB3.

Output Connections

(To DC Current or

Voltage Terminals)

Each transmitter channel is modeled after ANSI/ISA Type 4 transmitter with its

power separate and isolated from the input and output circuits.

•Output connections are polarized. The current and voltage output terminals of

each output share a common return (RTN). Current output is sourced from I+

and returned to R. The Voltage output is sourced positive at V+ with respect to

return R. Only one channel output terminal (voltage or current) may be loaded

at a time, current or voltage, but each channel may be different.

•Variations in load resistance has negligible effect on output accuracy when

load limits are respected with respect to output type (see below).

Observe proper polarity. Note that twisted-pair wiring is often used to connect the

longest distance between each field output and its remote load as shown above.

Additionally, shielded twisted pair wiring is recommended for best results. An

output connection to earth ground at each output return will help protect the

isolated output circuit from damage in noisy environments.

WARNING: For compliance to applicable safety and performance standards,

the use of twisted pair output wiring is recommended. Failure to adhere to

sound wiring and grounding practices as instructed may compromise safety,

performance, and possibly damage the unit.

TIP - Ripple & Noise: Place additional capacitance at the load to help reduce the

60Hz/120Hz ripple sometimes present in industrial applications. For large 60Hz

ripple, connect an external 1uF or larger capacitor directly across the load to reduce

excess ripple. For sensitive applications with high-speed acquisition at the load,

high frequency noise may be reduced significantly by placing a 0.1uF capacitor

directly across the load, as close to the load as possible.

Power Connections

The power terminals are reverse

polarity protected.

IMPORTANT –External Fuse: If

this unit is powered from a supply

capable of delivering more than 3A

to the unit, it is recommended that

potential fault current be limited

via a high surge tolerant fuse rated

for a maximum current less than

3A (for example, see Bel Fuse MJS

or RJS fuse types).

The unit is powered from 6-32V DC (36V DC peak) by connecting power as shown

below. This transmitter can be optionally powered (or redundantly powered) via

the DIN rail bus when coupled to an optional DIN rail bus connector (Acromag

Model 1005-063) with a bus terminal block (Acromag 1005-220 or 1005-221). This

optional power connection method can allow several dual channel modules to

share a single power supply without wiring power to each power terminal block

individually.

•Power connections are isolated from each input and each output. The

supply voltage should be from 6-32V DC. This voltage must never exceed

36V DC peak, or damage to the unit may result.

•Variations in power supply voltage between the minimum required and

32V maximum, has negligible effect on transmitter accuracy.

•Note the placement of earth ground at power. The power cable shield and

DC- should ideally be grounded closest to the module.

Power Connections…

CAUTION: Risk of Electric Shock –More than one disconnect switch may be

required to de-energize this equipment before servicing.

IMPORTANT –External Fuse: If unit is powered from a supply capable of delivering

more than 3A to the unit, it is recommended that this current be limited via a high

surge tolerant fuse rated for less than 3A (for example, see Bel Fuse MJS or RJS fuse

types).
