Monitor-H61 is both a remote terminal unit (RTU) and a data logger designed for remote monitoring of electrical substations, using digital and analog inputs/outputs (position or fault signaling contacts of equipment, DGPT2 signaling contacts, PT100 or PT1000 temperature sensors, etc.), and RS485 and Ethernet ports to integrate all existing measurement or control devices, communicating via the Modbus protocol (digital meters, electrical measurement units, digital protection relays, temperature and humidity sensors, etc.).

It is compatible with all meters, measurement units, and protection relays on the market (ABB, Elster, Schneider Electric, GE, etc.) communicating via Modbus. Monitor-H61 can manage up to 32 Modbus slave devices, including its own input/output expansion modules. It integrates easily and intuitively into any Modbus-compatible SCADA system on the market.
