On/Off switch, ideal for testing application software
Ability to simulate an external input
Built-in LED status indicator
Small footprint design matches that of other G4 I/O modules
Debounced for rapid counting
Passes NEMA showering arc test (ICS 2-230) Opto 22's G4SWIN input test module is used to simulate an input on an I/O mounting rack. Each module contains a toggle switch that closes a contact on the logic side of the module. An internal resistor limits the current through the switch and provides a load similar to that of an actual input module. An internal debounce circuit allows rapid switch closures without false counts.
