Function
This isolated barrier is used for intrinsic safety applications.

Power supply
PWR
The device converts RTD input signals or thermocouple input
signals in the hazardous area to 0/4 mA ... 20mA signals in the
safe area.
Programming jack
For temperature measurements with thermocouples the cold
junction module E-CJC is used to enable cold junction
compensation.
PRGRM.
If required the device can be used as a dual output single
channel unit, using channel 1 input.
The cold-junction temperature is measured by channel 1, so if
only one channel is to be used with a thermocouple, it must be
channel 1.
A fault is indicated by LEDs acc. to NAMUR NE44 and by
user-configured fault indication outputs.
The device is easily configured by the use of the PACTware
configuration software.
