Cat.No. B- GC83 Digital Indicators & GC93 Digital Meter Relay OUTLINE Model GC83 has been designed exclusively for indication. Model GC93 is equipped with a comparator like a relay and is applied to a pressure monitor and control. These indicator and meter relay receive a industrial common signal of 4 ma to 2 ma and V to 5 V and indicate pressure, etc., eliminating individual reading errors. A transducer driving 5 V power source or transmitter driving 24 V power source is built in, making wiring work easier.
