Item description

The input module directly connects to Pt or Ni resistance sensors and potentiometers.

It can be operated as a 2-channel (2- and 3-wire technology) or 4-channel (2-wire technology) module.

The bus module linearizes the entire temperature range. A sensor error (short circuit, line break or measuring range overflow) is indicated by a red
LED.

The module can be configured via WAGO‐I/O‐CHECK or GSD files.

The module features multiple setting options and high accuracy.

The module is ideally suited for operation in harsh environmental conditions:

- strongly extended temperature range

- higher dielectric strength and EMC resistance

- higher vibration and shock resistance
