D6072
- SIL 2 Multifunction Temperature Converter
G.M. International ISM0216-5
2
General Description:
The single and dual channel Temperature Signal Converter D6072S and D6072D accepts a low level dc signal from millivolt, thermocouple or resistance/RTD or
transmitting potentiometer sensor and converts, with isolation, the signal to drive a load, suitable for applications requiring SIL 2 (according to IEC 61508:2010) 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 D6072D) connecting compensation RTD to one of the two channels.
For D6072D module: duplicator function provides two independent outputs from one single input. Output function can be configured as: average, subtractor, low/high or redundancy
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.
Functional Safety Management Certification:
G.M. International is certified by TUV to conform to IEC61508:2010 part 1 clauses 5-6 for safety related systems up to and included SIL3.
