4-20mA Signal Isolators
Signal isolators receive a 4-20mA process current inputs and provide an isolated 4-20mA output signal. On multi-channel units, each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals.
