Description
The I/O module 750-498 measures either voltages (mV) in the field range or evaluates thermocouples. Depending on the sensor selection of the corresponding I/O module, the voltage value is output directly or converted to the corresponding temperature value. The I/O module uses the measured values supplied by the thermocouple and the cold setting temperature to determine the appropriate temperature at the location of the thermocouple used. The I/O module has 8 input channels and enables the direct connection of thermocouples in 2-wire technology. The field level and the system level are electrically isolated from each other.
