The RTD (resistive temperature device) input module allows the direct connec-
tion of Pt or Ni resistance sensors.
The connection of 2- or 3-conductor sensors is possible.
The module linearizes the entire temperature range automatically. A sensor er-
ror is indicated by a red LED.
A green LED indicates readiness for operation and trouble-free communication
with the buscoupler.
The shield (screen) is directly connected to the DIN rail.
