Description

The 750-498 I/O Module measures either voltages (mV) in the field or analyzes thermocouples.

Depending on the sensor selection for the respective I/O module, the voltage value is output directly or converted into the respective temperature value.

Based on the measured values supplied by the thermocouple and the cold junction temperature, the I/O module determines the corresponding temperature at the measurement point of the thermocouple used.

The I/O module has eight input channels, providing a direct connection from thermocouples to 2-wire sensors.
The field level and the system level are electrically isolated from one another.
