The connector card has two sets of connections, allowing for a continuous run to the next module ® Registered trademark of Schneider Electric. Model 5100-02-IT Combustible Gas Sensor Module 1. PRODUCT DESCRIPTION Combustible Gas Sensor Module is a member of the Sentry family of gas sensor transmitter modules.
Standard on the 5100-02-IT is an explosion-proof, rain-tight cast aluminum electrical housing (Figure 1-3) with three ¾” FNPT conduit hubs. The 5100-02-IT-SS has a 316 Stainless Steel enclosure (Figure 1-2). Both enclosure covers have a viewing window. The design of the enclosure allows 3-way mounting choices as shown in figure 1-1.
DC power between 10 VDC and 30 VDC. Regulated DC power must be supplied from a separate source, or from an approved Sentry or Figure 1 - 1: Model 5100-02-IT Combustible Sensor – Mounting Options Model 5100-02-IT Combustible Gas Sensor Module controller.
AC Voltage conductors are not to be run in the same conduit as DC voltage 2.3.1 CATALYTIC BEAD SENSOR MODULES Model 5100-02-IT Gas Sensor Modules are FM performance approved for detection of Combustible gas (methane and hydrogen). The sensor is cross sensitive to the combustible gases indicated in Table 2-1.

Note that the 5100-02-IT has a gas factor scaling feature in which a calibration standard of Methane or Propane may be used in conjunction with scaling factors to cause alarm function in %LEL scale of another gas. See Appendix G.
After the warm-up period has expired, the display will indicate the gas concentration. Also, the instrument loop will be released to output current in the range of 4 to 20 mA. The actual current is linear with the gas concentration. Model 5100-02-IT Combustible Gas Sensor Module 3. QUICK START Page: 9...
ANALOG 4-20 MA OPERATION The 4-20 mA output for the 5100-02-IT can be either 3-wire (ISA Type 3 Circuit) or standard (ISA Type 4 Circuit 4-wire) operation. If using 3-wire operation, use a minimum of 18 AWG, shielded, 3-conductor cable up to 2000’.
Sentry controller. Shield must be cut and dressed at the module end so that no part of it comes in contact with the conduit or ground. Be sure to follow all local electric code and safety requirements when installing the 5100-02-IT Gas Sensor Module 4.2.4 GENERAL Install conduit as required by local code or construction specifications.

%LEL scale of another gas. See Appendix I for a list of the scaling factors. Note that if the 5100-02-IT is interfaced to a Sentry controller that the gas factor can be set in the Sentry or the Gas Sensor Module but NOT IN BOTH. It is recommended that the gas factor be adjusted in the Gas Sensor Module so that the display values on both the Gas Sensor Module and the Sentry are matched.
