CONTEC DIO-0808LY2-USB Digital I/O USB Terminal
8-channel isolated digital input and 8-channel isolated digital output USB terminal for PC-based industrial control, monitoring, automation, and test systems.
Isolated Digital I/O Expansion via USB
The CONTEC DIO-0808LY2-USB is a compact USB digital I/O terminal designed to add isolated digital signal input and output capability to PC-based control, monitoring, automation, and test systems.
It provides 8 opto-coupler isolated digital inputs and 8 opto-coupler isolated open-collector outputs for 12 to 24 VDC signals. USB bus power eliminates the need for a separate power supply for the unit, while screw-terminal connections simplify integration with industrial equipment.8 Inputs / 8 OutputsOpto-isolated digital I/O for industrial signal interfacing
