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.
Opto-isolated inputs — 8 channels (12-24VDC) with 200µs response, compatible with current sink/source output.
Independent commons — each output channel has independent common for flexible power supply configuration.
Bus isolation — USB (PC) isolated from input interfaces by opto-couplers and output interfaces by relays.
