The input module directly connects to Pt resistance sensors.
The connection of 2- or 3-conductor sensors is possible.
The module automatically linearizes the entire temperature range.
A sensor error is indicated by a red LED.
A green LED indicates readiness for operation and error-free communication
with the buscoupler.
The shield (screen) is directly connected to the DIN rail.
All listed sensor types are supported by the configurable variation.
Set-up via WAGO-I/O-CHECK software.
