2 inputs for resistance temperature measurement For PT100 and PT1000 Configurable sensor type per channel Direct resistance measurement Configurable 2- or 3- wire connections per module Configurable filter time The module is equipped with 2 inputs for PT100/PT1000 resistance temperature measurement.
This module is designed for X20 6-pin terminal blocks. If needed (e.g.
for logistical reasons), the 12-pin terminal block can also be used.
