Model 5100-XX-IT Toxic Gas Sensor Module – Mounting Options

1.4.8TRANSMITTER ELECTRONICS

Electronic Assembly consist of one top transmitter board (connected to the cover plate) and on lower interface board. Connectors for wiring for power, signal interface and alarm relays are located on the interface board assembly

1.4.9SENSOR ASSEMBLY

The sensor assembly includes an explosion proof housing containing the gas sensor and a wiring harness for connection to the transmitter. The sensor assembly threads into one hub of the enclosure. The exposed end of the sensor assembly is threaded to allow connection of a rain-shield or calibration gas delivery fitting.

1.5INTERCONNECT WIRING

Not supplied with the sensor module, but necessary to the installation and operation is the multi conductor wiring which connects the module 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.

1.6POWER REQUIREMENTS

IT modules operate 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.
