PA0891 EP-4 IOT THERMAL PROTECTION RELAY - TEMPERATURE MONITOR FOR DRY-TYPE TRANSFORMER by electron
Get a quote
The electron PA0891 is an EP-4 IoT thermal protection relay and temperature monitor designed for dry-type transformers. This device features a signal input capable of accommodating up to four RTD PT-100 temperature sensors. For operational integration, it provides an RS-485 digital output and one analog output, supporting Modbus RTU, DNP 3.0, TCP via Wi-Fi, and MQTT protocols to enable real-time parameter access and remote commands. The unit includes three independent temperature setpoints—Ventilation, Alarm, and Shutdown—for each connected sensor. It is equipped with four isolated relays dedicated to alarm and shutdown functions, plus one isolated relay for fault indication. Additionally, an integrated Wi-Fi modem with a 3 dBi antenna immediately transmits collected data to a BrokerMQTT Server for platform accessibility.
