6Oi6Ro — Isolate & Switch

Why 6Oi6Ro

Switch Equipment Directly

6 high-quality Omron relays rated 16A at 230V — directly control inverters, contactors, pumps, and other industrial equipment.

Noise-Free Signal Reading

6 opto-isolated inputs eliminate ground loop issues and protect against industrial noise, enabling reliable signal reading from any source.

Standalone Automation

Built-in rule engine runs up to 8 automation rules locally. Continues operating without a Modbus master or network connection.

Use Cases

Industrial Signal Switching

Receive clean digital signals from PLCs, sensors, or other controllers via opto-isolated inputs. Route signals to equipment via 16A relays.

VPP Relay Control

Receive switching commands from a VPP platform via RS-485 Modbus. Switch contactors, breakers, and other grid equipment via 6 high-current relays.

Equipment Interlocking

Use built-in automation rules to implement safety interlocks — automatically controlling relay outputs based on digital input states, independent of network connectivity.
