Analog I/O module DC-TC

for thermocouples4 analog inputsDIN rail

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 • Electronic cold junction compensation • Malfunction detection • Highly accurate thanks to the 24-bit analogue/digital converter • Supported Types • PT13%Rh-Pt (type R, IEC 584) • Fe-CuNi (type J, IEC 584) • Fe-CuNi (type L, DIN 43710) • PT30%Rh-Pt6%Rh (type B, IEC 584) • Cu-CuNi (type T IEC 584) • NiCrSi-NiSi (type N, IEC 584) • PT10%Rh-Pt (type S, IEC 584) • NiCr-CuNi (type E, IEC 584) • NiCr-NiAl (type K, IEC 584) • Signal : For direct connection of thermocouples • Connection type : Plug-in connectors with push-in spring connection or optionally pluggable screw terminals. • Resolution : greater than 0.1 °C • Absolute measurement uncertainty (within the maintenance interval) : ±2 °C • Operating voltage : 24 V (18…30 V), supply via bus • Power consumption : 60 mA • Input resistance : approx. 10 kOhm, due to sensor break detection • Dimensions (HxWxD) : 99.5 x 22.5 x 114.5 mm • Working temperature : 0…+60 °C • Storage temperature : 0…+65 °C • Humidity : 90 %, not condensing • For the record of : Temperatures using thermocouples
