The 9481 series mV temperature input module for Zone 1 has eight channels for the Ex i operation of thermocouples that comply with DIN, IEC and GOST, as well as mV sources. Earthed thermocouples can also be connected. The module features internal cold junction compensation.
All inputs are short-circuit proof, galvanically separated from the system and individually monitored to check for line faults.
- Eight channels for thermocouples or mV sensors
- intrinsically safe Ex ia inputs with line fault monitoring
- modules in Zone 1 can be hot swapped
