Detcon Itm Ir-700 Infra-Red 0-100% Atex Approval Itm Only

Detcon IR-700 Intelligent Transmitter Module (ITM) Spare Part. Includes extensive I/O circuit protection, sensor pre-amplifier, on-board powersupplies, microprocessor, LED display, magnetic programming switches, a linear 4-20mA DC output, and a Modbus RS-485 output.The Intelligent Transmitter Module (ITM) is a fully encapsulated microprocessor-based package that accepts a plug-in field replaceable combustible gas sensor and for IR-700 CO sensors, a plug-in replaceable CO sensor. Circuit functions include extensive I/O circuit protection, sensor pre-amplifier, on-board power supplies, microprocessor, LED display, magnetic programming switches, a linear 4-20mA DC output, and a Modbus RS-485 output. Magnetic program switches located on either side of the LED Display are activated via a hand-held magnetic programming tool, thus allowing non-intrusive operator interface with the ITM. Calibration can be accomplished without declassifying the area. Electrical classifications are Class I, Division 1, Groups B C D and Class I, Zone 1, Group IIB+H.
