6.7 Temperature Input module
These modules accept inputs from low-level dc sources such as thermocouples or RTDs in
hazardous areas and converts them into 4/20mA signals to drive safe area loads.
Thermocouples Early burnout detection (EBD)
When EBD is selected, the resistance of the thermocouple circuit is monitored and an alarm is
raised when there is an increase of more than 50W. This enables preventative maintenance to
be conducted on the field installation before the thermocouple actually breaks.
Configuration using PCS45/PCL45USB
Use PCS45 software, in conjunction with the PCL45USB serial link, to configure these modules.
Instructions are contained within the software. See Section 6.9 on page 58 for further details.
