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.
Includes 3720 PC/104 board, ribbon cable, and mounting plate with removable screw terminals for installation in a Relio enclosure.
