Ethernet IO

This Smart IO device is an Ethernet device with 4 Integrated controllable relays and 4 integrated digital inputs. The device allows for web based control and monitoring of it’s relays and inputs and may be integrated into distributed control and network management systems.

Each of the Relays and inputs can be individually configured to send customized emails and notifications. The device supports a wide variety of protocols that it is compatible with over Ethernet. Supported integration protocols: SNMP Polling and Traps, Modbus TCP featuring addressable registers, and DNPv3 TCP for integration with utility and other automation control systems.

Bi-Directional Contact Closure over Ethernet

When using RLH’s System Link feature, two of these devices can link up and establish a tunnel over an Ethernet network. When a link is established between two Smart IO devices the outputs at each location will mirror the input states at the opposite end. Providing bi-directional alarming between two locations over an Ethernet network.
