This I/O module is suitable for the direct connection of up to 4 thermocouples. The cold junction compensation is carried out electronically and can be optionally switched off for the measurement of exact temperature differences.
The measurement supplied by the resistance sensor is linearised and converted to °C.
• 4 inputs for thermoelements
