Periphery module RTD8O2 (8 analog in- and 2 analog outputs)

The periphery module PM-RTD8O2 is a compact module designed for applications to measure resistances like PT100/1000, NI100/1000, KTY81 etc. There can be configured 2-, 3- and 4-wire connections, what makes this product very flexible. 2 voltage outputs are too.

  • insertion stripe with description field for every signal
  • cage-clamp connector with 2 lift arms or bolt flanges on side
