The Yokogawa UP55A-020-11-00 is a Signal Conditioner / Isolator Module designed for use with Yokogawa's UTAdvanced and UT55A series signal conditioning systems.
Its primary function is to electrically isolate a standard 2-wire 4-20 mA DC input signal and convert it into an identical, isolated 4-20 mA DC output signal. This isolation is crucial for breaking ground loops, preventing noise interference, and protecting sensitive control system equipment from voltage surges or faults occurring in the field.
