Ethernet IO

The Smart Relay Output is an Ethernet device with 4 Integrated controllable relays. The device allows for web based control of the relays and may be integrated into distributed control and network management systems to allow those systems to controlled it’s Relays.

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

Contact Closure Over Ethernet

The RLH Smart Relay Output may be paired with an RLH Smart Input Sensor. When using RLH’s System Link feature, the two devices become linked establishing a tunnel over an Ethernet network and will transport a digital outputs being received by the Input Sensor through the Ethernet tunnel to the linked Relay Output device. The System Link feature can be set up via: One to One, Many to One, and One to Many allowing for event distribution and consolidation as needed.
