Digital Input Guide
A digital input is a device that can read the state of a digital signal. Digital signals are either high or low (1 or 0). Check out this guide for more information.

Digital Inputs
The Digital Inputs are activated by an external voltage source, triggering on a wide voltage range: 4 to 30VDC. They provide built-in filtering, to eliminate false triggering from electrical noise. They can be used to convey the state of on/off devices, such as push buttons, limit switches, relays.
Digital Outputs
The Digital Outputs can be used to directly control substantial devices, switching up to 30VDC at up to 2 Amps. The Output acts as a switch to ground, and is protected from transient voltages typical when switching inductive devices - relays, solenoids, motors. The Outputs can be used to directly control devices requiring substantial power such as incandescent lights, high power LEDs, relays, solenoids, motors.
