Module overview
• Detection of standard analog input signals for
measurement of temperatures
• Connection of thermoelements of the types
B,E, J, K, N, R, S and T
• Electronics galvanically isolated from the field level
via optocoupler
• Base modules with internal cold junction
compensation
• LEDs for indicating diagnostics
• Wiring diagram printed on the module lid
