This signal conditioner provides the galvanic isolation beetween field circuits and control circuits.
The device converts the signal of a resistance thermometer, thermocouple, potentiometer, or voltage source to a proportional output current. It
also provides a relay trip value.
The removable terminal block K-CJC-** is available as an accessory for internal cold junction compensation of thermocouples.
A fault is signalized by LEDs acc. to NAMUR NE44.
The device is easily configured by the use of the PACTware configuration software.
For additional information, refer to the manual and www.pepperl-fuchs.com.
