Function
This isolated barrier is used for intrinsic safety applications. It is designed to connect RTDs, thermocouples, or potentiometers in the hazardous area, and provide a proportional 0/4 mA ... 20 mA signal to the safe area.
The barrier offers 3-port isolation between input, output, and power supply.
A removable terminal block K-CJC-** is available for thermocouples when internal cold junction compensation is desired.
A fault is indicated by a red flashing LED per NAMUR NE44 and user-configured fault outputs.
The unit is easily programmed with the PACTwareTM configuration software.
A collective error messaging feature is available when used with the Power Rail system.
