These transmitters accept 4-20mA process current inputs and provide isolated 4-20mA outputs to DCS or other indicators. Each channel is isolated from the others to prevent interaction between the channels. Available as AC or DC powered, they provide a 24Vdc excitation supply, to power one or two 2-wire transmitters.
For easy trouble shooting each unit has LEDs and diagnostic test points. Power LEDs help identify open circuits in the output loop, whilst a 10Ohm precision resistor enables monitoring of the output signal without disturbing the field wiring.
