Made for conditioning process loops, this DIN-rail signal conditioner accepts a 0 to 50 V DC or 0 to 50 mA process signal. It runs on a DC supply and rescales the input to a standard process current or voltage output. Works great for isolating and transmitting signals from process voltage and current loops to PLCs and process instrumentation.

The DMD4380 accepts a dc voltage or current input and provides an optically isolated dc voltage or current output that is linear to the input. It provides filtering, amplifies, and converts the input signal to the selected dc voltage or current output that you select.
The 3-way 1200V isolation eliminates ground loops, common mode voltages and greatly reduces noise pick-up. The power supplies can also be wired to sink or source which allows the DMD4380 to be used with any combination of powered or unpowered mA inputs and powered or unpowered mA outputs including passive mA devices.
Features such as red and green LEDs that vary in intensity to show input and output activity and an output test button help make set-up and troubleshooting fast and easy.
