2-channel signal conditioner, 24 V DC supply (Power Rail), Thermocouple, RTD, potentiometer or voltage input, Usable as signal splitter (1 input and 2 outputs), Current output 0/4 mA ... 20 mA, Sink or source mode, Configurable by PACTware, Line fault (LFD) and sensor burnout detection, Up to SIL 2 acc. to IEC 61508/IEC 61511pa. This signal conditioner provides the galvanic isolation between field circuits and control circuits. The device converts the signal of a resistance thermometer, thermocouple, or potentiometer to a proportional output current. The device can also be configured as a signal splitter. 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 and a separate collective error message output. 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.
