D5072-099
- SIL 2 Temperature Signal Converter
G.M. International ISM0389-0
General Description:
The single and dual channel Temperature Signal Converter D5072S-099 and D5072D-099 accepts a low level dc signal from millivolt, thermocouple or resistance/
RTD or transmitting potentiometer sensor, located in Hazardous Area, and converts, with isolation, the signal to drive a Safe Area load, suitable for applications requiring SIL 2 level
(according to IEC 61508:2010 ed.2) in safety related systems for high risk industries. Output signal can be direct or reverse. Modbus RTU RS-485 output is available on Bus connector.
Cold junction compensation can be programmed as:
- Automatic: provided by an internal temperature sensor;
- Fixed: to a user-customizable temperature value;
- External: making use of an external RTD;
- Remote: (only D5072D) connecting compensation RTD to one of the two channels.
For D5072D-099 module: duplicator function provides two independent outputs from one single input. Output function can be configured as: average, subtractor, low/high or redundan-
cy selector. Modules are provided with alarm function, which is available via solid state contact output, Termination Board and Power Bus. Mounting on standard DIN-Rail, with or
without Power Bus, or on customized Termination Boards, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
