Read full descriptionHide description
USB 2.0 digital I/O unit featuring 8 channels of opto-coupler isolated inputs (12-24VDC) and 8 channels of SPDT relay outputs (Form C) with independent commons. Supports high-capacity output up to 6A 240VAC / 5A 28VDC per channel. Compact design with DIN-rail, magnet, or screw mounting options.
Relay Output & Digital
Input USB I/O
The DIO-0808RN-USB is a USB 2.0-compliant digital I/O unit that extends PC capability with 8 opto-coupler isolated inputs and 8 SPDT relay outputs with independent commons. The high-capacity relay outputs (6A 240VAC / 5A 28VDC per channel) can directly control industrial equipment. USB bus isolation provides excellent noise immunity for reliable operation.
- Low current outputs
- Shared commons
- No opto-isolation
- Limited mounting options
- 6A 240VAC relay outputs
- Independent commons per channel
- Opto-coupler bus isolation
- DIN-rail, magnet, or screw mounting
Independent commons for flexible control — each relay output has its own common terminal, allowing connection to different external power supplies for diverse load control.
Built for Industrial
I/O Applications
The DIO-0808RN-USB is designed for industrial control applications requiring reliable digital input and high-current relay output. Opto-coupler isolation (500Vrms) on inputs and relay isolation on outputs provide excellent noise immunity. The compact 188 × 78 × 30.5 mm design fits easily in control panels.
-
High-capacity relay outputs — 8 SPDT relays with 6A 240VAC / 5A 28VDC rating, mechanical life 10,000,000 operations.
