Energy metering gateway Perseus Energy 240, RS-485 Modbus/RTU to Modbus/TCP, metal housing, plain unit - HW group 600850
Perseus Energy 240 brings readings from power meters, UPS systems and HVAC units onto the LAN via RS-485 Modbus/RTU and publishes them over Modbus/TCP, SNMP, MQTT or to a SensDesk portal. The gateway has an RS-485 interface only, with no RJ11 ports and no digital inputs. This plain unit ships without a power adapter.

Description
Plenty of power meters, UPS systems and air conditioning units only speak Modbus/RTU. Perseus Energy 240 puts that data on the network, handling up to 100 meters with 1000 variables that can be evaluated on the device and read out over Modbus/TCP, SNMP, MQTT or XML.
Benefits
- Protocol conversion: works as a Modbus/RTU (RS-485) to Modbus/TCP gateway and as a Modbus/RTU to MQTT or SNMP converter.
- LAN data too: the Meters API also collects values from other network devices via SNMP, Modbus/TCP, MQTT and HWg XML.
- On-device logic: local alarms, conditions and actions, Lua scripts, calendar and scheduler, with alerts by email or SNMP Trap.
- Ready for control systems: data can feed third-party SCADA or SNMP-based NMS platforms as well as SensDesk portals.
- Metal housing: operating range -30 to +85 °C, IP40.
Applications
- Modbus gateway in server rooms or technical rooms for power meters and UPS
- Connecting air conditioning and cooling units with a Modbus/RTU interface to NMS or SCADA
- Data concentrator for all meters at a remote site
- Telecom cabinets and base transceiver stations
- Warehouses, pharmaceutical storage and greenhouses
Compatibility
- Modbus/RTU devices from HW group and third parties on RS-485
- Other HW group devices on the LAN via XML, for example STE2 R2
- SensDesk Technology portals, HWg Monitor app
