Rugged Ethernet IO Device with 4 Digital Inputs for Monitoring and Alarming
The Smart Input Sensor is a Ethernet device with 4 digital inputs. The device allows for web based monitoring of the inputs and may be integrated into distributed control and network management systems to allow those systems to alarm and monitor field devices. Each of the Inputs can be individually configured to send customized emails and notifications when an event is recorded. 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 Input Sensor has the ability to be paired with an RLH Relay Output Device. When using RLH’s System Link feature, the two devices become linked establishing a tunnel over an Ethernet network and will transport a digital output signal 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.
