The dual channel Temperature Signal Converter D5072D accepts a low level dc signal from millivolt, thermocouple or 2-3-4 wire 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) in safety related systems for high risk industries.

Output signal can be direct or reverse. Cold junction compensation can be programmed as: – Automatic: provided by an internal temperature sensor; – Fixed: to a user-customizable temperature value; – Remote: connecting compensation RTD to one of the two channels.

Modules are provided with alarm function which is available via photoMOS output, Termination Board and Power Bus. Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area or in Zone 2.

Hazardous area:
Millivolt or thermocouple type A1, A2, A3, B, E, J, K, L, LR, N, R, S, T, U, or 2-3-4 wire RTD Pt50, Pt100, Pt200, Pt300, Pt400, Pt500, Pt1000 to IEC, Pt100 to ANSI (0.3916), Ni100, Ni120 to DIN43760, Pt46, Pt50, Pt100, Pt200, Pt300, Pt400, Pt500, Cu50, Cu53, Cu100 to GOST6651 and Cu9.035 (or Cu10), or 3 wire transmitting potentiometer (100 Ω to 10 kΩ). 4-wire RTD input only on D5072S. Possibility of configuring user customized sensor (TC or RTD). Choice between °C/°F.
