The Perseus Monitoring 150 TSet is a professional 1U rack monitoring platform for data centers, server cabinets, and AV installations. The device monitors up to 1,000 variables via LAN and integrates external sensors, detectors, and third-party devices into a central alarm and automation system. In addition to the base unit, the TSet includes 19" rack mounts (RM2), a WLD sensor cable Type A (2+2 m), a 19" rack temperature sensor (Temp-1Wire Rack19), an MK4 door contact, and a universal 12V/1.5A power supply—everything needed for direct installation and commissioning.
Eight RJ11 ports accommodate 1-Wire UNI sensors from the HW group (temperature, humidity, current, voltage, and much more; max. 100 external sensors). Third-party Modbus/RTU sensors can be integrated via RS-485. 16 digital inputs (DI) for dry contacts allow the connection of smoke detectors, door contacts, fan failure detectors, and other detectors. Four relay outputs (DO) directly control external actuators such as air conditioning systems, ventilation systems, or access control systems. A WLD zone input detects water leaks via external sensing cables.
The Perseus 150 is powered by 9–30 V DC, -48 V DC, or PoE (IEEE 802.3af), making it suitable for a wide variety of rack environments. The included RM2 rack mounts allow for direct 19" mounting in a 1U format. The operating temperature ranges from -30 to +65 °C.
The Meters API reads sensor values from other LAN devices (e.g., STE2 r2, SNMP-enabled UPS, air conditioning units via Modbus/RTU) and links this data with its own measurements for complex alarm logic. Lua scripting, schedulers, and virtual sensors enable custom automation without external software. SMS alerts can be implemented using an external SMS gateway (e.g., SMS-G3).
All measurement values are accessible via Open API: SNMP (v1/v2/v3), MQTT, Modbus/TCP, and XML. Integration with SensDesk (paid) or HWg-Cloud (free) enables graphs, device status alerts, PDF reports, and SCADA connectivity. Remote access via integrated web server, HWg-Config, or HWg Monitor app (iOS/Android).
