The 3720 PC/104 digital I/O interface provides 16 optically isolated inputs for connection to devices including sensors, switches, push buttons, and other user inputs. The inputs can sense both AC and DC voltage while providing optical isolation, which eliminates spikes and surges present in industrial environments.
The inputs on the 3720 are rated for 3-13V. For 10-30V inputs, order the 3720H.
Sealevel’s SeaIO Classic software drivers and utilities make installation and operation easy using Microsoft Windows operating systems.
