WebContact closures are designed for connecting switches, buttons, motion detectors, or other devices that make an electrical connection between two conductors. Digital outputs are designed for connecting LED indicators, small relays, buzzers, pilot lights, and most anything that can be powered from a small DC voltage. WebInputs can sense a Dry Contact closure; Inputs can accept a DC voltage signal from 12 – 48 Volts ...
WebThe inputs on this controller were designed for contact closure interface applications. Connect the inputs via screw terminals to buttons, switches, magnetic door switches, or any other contact-closure source. NCD Push Notification devices are powered from a 12VDC power supply using a 2.1mm barrel connector or a 2-position screw terminal. WebContact Closure Input—This setting enables an in-ternal pull-up resistor, allowing actuation by a contact closure to ground. This can be through a switch, set of relay contacts, etc. None Internal pull-up resistor to +12 V. When contacts are closed, GPIO In = 0 V; when open, GPIO In = +12 V. Potentiometer (10 kΩ, 12 V)—In this setting, the

You can use a 3V relay driven by your 3V signal. If the 3V signal does not have enough current capability to drive a 3V relay directly you will need to add a driver transistor and supply appropriate power for the relay coil. Typically this would involve a transistor, base series resistor, diode across the ...
