The Model IR2100 Infrared Point
Detector is a microprocessor-based hydrocarbon gas detector
that continuously monitors combustible gases and vapors within
the lower explosive limit (LEL) and provides alarm indication.
All electronics are contained within an explosion-proof housing
so that the IR2100's detector information can be processed locally.
The IR2100 operates with a 4-20mA signal, which is proportional
to 0 to 100% LEL gas concentration at the detector. RS-485 serial
communications are MODBUS RTU compatible. The RS-485 output
provides status, alarm, fault and other information for operation,
troubleshooting or programming the unit. CSA, FM, ATEX, CE Marking,
GOST, Kazakhstan approved. SIL 2 suitable, certified by FM to IEC 61508.
