The Low Energy PIU (Process Interface Unit) is the TDC 2000 field I/O device for remote or isolated low level analog inputs, typically thermocouples and RTDs. The LE PIU uses remote multiplexer boxes for field termination. Up to 16 mux boxes of 16 points each may be daisy-chained to a single common card file (CCFA)
Common card files, complete mux boxes, relay boards and termination boards are available from WPC to keep your LE PIU subsystem in good working condition.
