•Integral alphanumeric LED display
•4-20 mA output
•Modbus®RTU interface
•SMC Sentry interface
•316 Stainless steel enclosure option
•Auxiliary integral relay option
•Remote display option
•Low maintenance and operation costs
The 5100-99-IT is designed and approved for installation and operation in hazardous locations.

described in this manual
1.3 MODES OF OPERATION
SENTRY INTERFACE
IT gas sensor transmitter can be connected to on Sierra Monitor Sentry Model 5000 controllers. When it is
connected to a Sentry system the IT transmitter must have a unique address which can be established by
setting an address between 1 and 8 on the Transmitter Address Switch accessible from the cover plate as
illustrated in Figur
Se
When the transmitter is operated in conjunction with a Sentry controller, the alarms outputs in the
transmitter can both be set to “Sentry”, allowing the Sentry controller to manage alarm acknowledge and
reset rather than the transmitter. The alarm relay outputs are triggered by the
the transmitter and can be independent of the settings in the Sentry controller.
The Sentry configuration allows daisy chain installation using the Sentry multiplex capability, thus reducing
costs by avoiding the requirement for wiring junction boxes. The connector card has two sets of

viewing window. The design of the enclosures allows 3-way mounting
hoices as shown in figure 1-3.
MODBUS OPERATION
An RS-485 Modbus RTU serial interface allows direct connection to standard PLCs and DCSs. The
Transmitter Address Switch (section 3.5) allows the user to select up to 16 different Modbus addresses.
Also, an additional 238 Modbus addresses (for a total of 254 different Modbus Addresses) are available
via menu selection. Figure 3-6 in this manual provides the wiring terminations for Modbus connections. The
5100-XX-IT provides th
a RS-485 connection.
ANALOG OPERATION
The 4-20 mA interface allows direct connection to standard analog controllers or PLCs. The 5100-XX-IT 4-
20 mA connection can be wired as a Type
50.00.01-1975 Standard (see figure 3-5).
REMOTE ALARM RESET (DIGITAL INPUT) (Figure 3-7)
An input is available for connection of remote alarm reset/acknowledge. Figure 3-7 provides the wiring
termination for connecting the remote alarm reset. Th
input can be wired as supervised or non-supervised.

1.3.8 TRANSMITTER ELECTRONICS
Electronic Assembly consist of one top transmitter board (connected to the cover plate) and a lower
interface board. Connectors for wiring for power, signal interface and alarm relays are located on the
interface board assembly
1.4 INTERCONNECT WIRING
Not supplied with the transmitter, but necessary to the installation and operation is the multi conductor
wiring which connects the transmitter to its power source and controller. Before this wiring is installed it is
important to read and understand the control system installation instructions to determine wiring
requirements and alternatives.
1.5 POWER REQUIREMENTS
5100-99-IT operates on DC power between 10 VDC and 30 VDC. Regulated DC power must be supplied
from a separate source, or from an approved Sentry or IT controller.

2. CAUTIONS & WARNINGS
2.1 INTRODUCTION
Although IT Transmitter is designed and constructed for installation and operation in industrial applications
including "hostile" environments, caution should be taken to insure that the installation is made in
compliance with this instruction manual and that certain procedures and conditions are avoided. This
chapter discusses the necessary cautions. Read the entire chapter prior to installation of the
equipment.
2.2 IT TRANSMITTERS - GENERAL
Avoid installing Transmitter where they will be unnecessarily exposed to wind, dust, water (esp. direct hose
down), shock, or vibration. Observe temperature range limitations.
2.3 WIRING
The manufacturer recommends that extra caution be taken where the installation is near any sources of
electromagnetic or radio frequency interference. Precautions include:
•Avoid running transmitter cable close to high power cables, radio transmission lines, or cables subject
to pulses of high current.
•Avoid running cables near large electric motors or generators.
•When the transmitter is to be operated in analog (4-20mA output) mode shielded cable is required.
•All splices must be via either a termination hardware system or soldered. Improperly spliced cable can
result in corrosion, resistance changes and system errors.
•Use low capacitance cable for RS-485 Modbus RTU Operation.
NOTE
Installation and wiring must be in accordance with the National Electrical Code. AC Voltage
conductors are not to be run in the same conduit as DC voltage conductors.
