Thank you for choosing Delta DVP-SS2. DVP-SS2 is a 14-point (8DI + 6DO) PLC MPU,

offering various instructions and with 8k steps program memory, able to connect to all

DVP-S series extension models, including digital I/O (max. 480 I/O points) and analog

modules (for A/D, D/A conversion and temperature measurement). 4 groups of

high-speed (10kHz) pulse output satisfy all kinds of applications. DVP-SS2 is small in

size and easy to install.

aThis instruction sheet only provides introductory information on electrical

specifications, general specifications, installation and wiring. For detailed information

on programming and instructions, please refer to “DVP-SS2 Operation Manual:

Programming”. For information about optional peripherals, please see individual

product instruction sheet enclosed with DVP-SS2.

aThis is an OPEN TYPE device and therefore should be installed in an enclosure free

of airborne dust, humidity, electric shock and vibration. The enclosure should prevent

non-maintenance staff from operating the device (e.g. key or specific tools are

required to open the enclosure) in case danger and damage on the device may

occur.

aDO NOT connect input AC power supply to any of the I/O terminals; otherwise

serious damage may occur. Check all the wiring again before switching on the power.

Make sure the ground terminal is correctly grounded in order to prevent

electromagnetic interference. DO NOT touch any terminals when the power is

switched on.

Dimension & Installation

Please install the PLC in an enclosure with sufficient

space around it to allow heat dissipation, See

[Figure 3].

Direct Mounting: Use M4 screw according to the

dimension of the product.

DIN Rail Mounting: When mounting the PLC to

35mm DIN rail, be sure to use the retaining clip to

stop any side-to-side movement of the PLC and

reduce the chance of wires being loose. The retaining clip is at the bottom of the PLC.

To secure the PLC to DIN rail, pull down the clip, place it onto the rail and gently push

it up. To remove the PLC, pull the retaining clip down with a flat screwdriver and gently

remove the PLC from DIN rail.

Wiring

1. Use 22-16AWG (1.5mm) single or multiple core wire

on I/O wiring terminals. See the figure in the right hand

side for its specification. PLC terminal screws should be

tightened to 1.90 kg-cm (1.65 in-lbs) and please use only

60/75ºC copper conductor.

22-16AWG

< 1.5mm

2. DO NOT wire empty terminal. DO NOT place the I/O signal cable in the same wiring

circuit.

3. DO NOT drop tiny metallic conductor into the PLC while screwing and wiring. Tear

off the sticker on the heat dissipation hole for preventing alien substances from

dropping in to ensure normal heat dissipation of the PLC.

Power Supply

The power input of DVP-SS2 is DC. When operating DVP-SS2, please note the

following points:

1. The power is connected to two terminals, 24VDC and 0V, and the range of power is

20.4 ~ 28.8VDC. If the power voltage is less than 20.4VDC, the PLC will stop running,

all outputs will go “Off”, and the ERROR indicator will start to blink continuously.

2. The power shutdown for less than 10ms will not affect the operation of the PLC.

However, the shutdown time that is too long or the drop of power voltage will stop the

operation of the PLC, and all outputs will go off. When the power returns to normal

- 4 -

status, the PLC will automatically resume the operation. (Please take care of the

latched auxiliary relays and registers inside the PLC when doing the programming).

Safety Wiring

Since DVP-SS2 is only compatible with DC power supply, Delta’s power supply modules

(DVPPS01/DVPPS02) are the suitable power supplies for DVP-SS2. We suggest you

install the protection circuit at the power supply terminal to protect DVPPS01 or

DVPPS02. See the figure below.

emergency takes place.

Input Point Wiring

There are 2 types of DC inputs, SINK and SOURCE. (See the example below. For

detailed point configuration, please refer to the specification of each model.)

Output Point Wiring

1. DVP-SS2 has two output modules on it, relay and transistor. Be aware of the

connection of shared terminals when wiring output terminals.

2. Output terminals, Y0, Y1, and Y2, of relay models use C0 common port; Y3, Y4, and

Y5 use C1 common port. See [Figure 7]. When the output points are enabled, their

corresponding indicators on the front panel will be on.

3. Output terminals, Y0 ~Y5 of transistor models use UP, ZP common port. See [Figure

8].

4. Isolation circuit: The optical coupler is used to isolate signals between the circuit

inside PLC and input modules.

Relay (R) output circuit wiring

cDC power supply dEmergency stop: Uses external switch

eFuse: Uses 5~10A fuse at the shared terminal of output contacts to protect the output circuit

fTransient voltage suppressor (SB360 3A 60V): Extends the life span of contact.

1. Diode suppression of DC load: Used when in smaller power [Figure 10a]

2. Diode + Zener suppression of DC load: Used when in larger power and frequent On/Off

[Figure 10b]

gIncandescent light (resistive load) hAC power supply

iManually exclusive output: For example, Y3 and Y4 control the forward running and reverse

running of the motor, forming an interlock for the external circuit, together with the PLC

internal program, to ensure safe protection in case of any unexpected errors.

jAbsorber: Reduces the interference on AC load [Figure 11]

fThe output of the transistor model is “open collector”. If Y0/Y1 is set to pulse output, the

output current has to be bigger than 0.1A to ensure normal operation of the model.

1. Diode suppression: Used when in smaller power [Figure 13a]

2. Diode + Zener suppression: Used when in larger power and frequent On/Off [Figure 13b]

gManually exclusive output: For example, Y3 and Y4 control the forward running and reverse

running of the motor, forming an interlock for the external circuit, together with the PLC

internal program, to ensure safe protection in case of any unexpected errors.
