Energy monitor Perseus Energy 242, M-Bus master, RS-485, 4 sensor ports, metal housing, plain unit - HW group 600851

Monitoring energy use and site conditions together usually means several data collectors. Perseus Energy 242 reads up to 100 M-Bus meters plus Modbus/RTU devices and 1-Wire sensors in one box, managing up to 100 meters with 1000 variables in total.

Benefits

• Built-in M-Bus master: up to 100 electricity, gas or water meters connect straight to the terminal block.
• Environmental sensing: 4 RJ11 ports for 1-Wire UNI sensors, up to 2 per port, covering temperature, humidity, voltage or current.
• Pulses and contacts: 2 dry contact inputs with S0 pulse counters and 1 WLD zone for a water leak sensing cable.
• Local control: 1 relay output rated 50 V and 1 A for air conditioning, ventilation or doors.
• Open interfaces: SNMP v1 and v3, Modbus/TCP, MQTT, BACnet/TCP and XML for building management and NMS.

Applications

• Energy and environmental monitoring in server rooms and technical rooms
• Consumption metering of electricity, gas and water meters over M-Bus
• Boiler rooms and heating plants
• Industrial machinery monitoring
• Greenhouses, food and pharmaceutical storage

Compatibility

• 1-Wire UNI sensors on RJ11: temperature, humidity (indoor and outdoor), voltage, current 0-30 A or 4-20 mA
• Detectors on the digital inputs: smoke, door contact, fan failure, power presence
• WLD water leak sensing cables
• Third-party M-Bus meters and Modbus/RTU devices
• Other HW group devices such as STE2 R2 via the Meters API over LAN
