Temperature Control TR42CMW5 ORION - LTĐ đại lý TR42CMW5 ORION Việt Nam

The TR42 is a temperature monitoring, control, and sensor relay (ANSI 49 protection relay) designed for 3-phase cast resin and dry-type transformers, regardless of voltage (kV) or power rating (kVA).

Its main function is to take real-time action based on temperature readings from the transformer windings and user-defined programming—such as activating or deactivating cooling fans, triggering alarms, or initiating trips.

The device includes an RS485 Modbus communication port for integration into SCADA or remote monitoring systems.

This transformer protection relay (ANSI 49) features four PT100 inputs for accurate temperature monitoring of dry-type or cast resin transformers. It offers two independent output contacts for controlling dual-stage fan cooling, useful during high ambient temperatures or overcurrent conditions, helping you maximize kVA output while avoiding thermal overload.  100% compatible with previous models.

• 4 RTD PT100 Inputs (3 wires)
• Real-time temperature display for each sensor
• Display and storage of the peak temperature reached by each RTD
• 4 independent programmable output contacts configurable from 0°C to 220°C for Level 1 alarm, Level 2 alarm, FAN1, and FAN2 control (new)
• Automatic fan mode and “Always ON” option for continuous ventilation
• Alarm relay for TR42 internal failure or PT100 sensor disconnection
• Weekly automatic fan start to protect fan bearings from seizing
• Isolated RS485 Modbus communication port for integration into SCADA and remote systems
• Optional 4–20 mA analog output corresponding to temperature readings
• 100% backward compatible with previous models
• QR code access to product documentation and tutorial videos
