420-DIG Digital Input & Output Isolator

420-DIG Digital I/O Isolator

(START-LIST)

Isolate Inputs or Outputs

DIN Rail Mounting

Low cost, Compact Solution

The 420-DIG digital isolator allows any high voltage digital signal to be connected to PLC or other I/O cards. A typical application would be to wire the feed to a 230Vac indicator lamp and the output direct to a PLC input, allowing the PLC to know when that indicator was on.

The output isolator acts as a low current relay, allowing PLC digital outputs to switch larger loads and isolate the PLC from any noise generated by the switching.

5000Vrms isolation is provided
