JYL25-A Electrical Contact Temperature Display Terminal

1. Product Introduction
The JYL25-A Temperature Display Management Terminal is a device designed for medium and low voltage power systems of 35kV and below. It works in conjunction with temperature measurement devices to provide centralized monitoring, early warning, data transmission, temperature display, historical curve query, and over-temperature recording of contact temperature data. All its technical indicators meet national standards. The product can communicate with temperature measurement devices via wired or wireless methods, managing up to 240 wireless temperature sensors simultaneously. It features an RS485 communication interface and uses the standard Modbus-RTU communication protocol, enabling quick integration with third-party terminal devices and computer monitoring systems for centralized data collection and forwarding. The product incorporates various anti-interference measures, ensuring stable operation in complex electromagnetic environments with high reliability.
