Overview
The ATC600 series wireless temperature measurement transceiver is designed for real-time monitoring of critical points in electrical systems such as switchgear, cable joints, transformers, and busbars. It collects data from various wireless sensors and transmits it via RS485 with MODBUS-RTU protocol, enabling seamless integration into SCADA, EMS, or other monitoring platforms. The series includes receiver models (-C, -M, -PD) and a repeater (-Z) to meet different application needs.

FAQ
ATC600-C supports up to 240 temperature sensors + 80 APD100 partial discharge sensors; ATC600-M supports 240 sensors (1440 points); ATC600-PD supports 240 temperature + 40 APD300-W.
For ATC600-C/-PD, receiving distance is 150m (470MHz) or 50m (433MHz) in open area; ATC600-M can receive up to 1km. The ATC600-Z repeater can extend the distance to 1km.
Yes, AHE100 is compatible with ATC600-C (special program required for APD100, but AHE100 works with standard -C). Please refer to the address table for humidity data.
Relay status can be read/written via MODBUS register 0202H. The output is controlled by the upper computer; no local setting is available.
Summary
The ATC600 series wireless temperature transceiver provides a reliable and scalable solution for monitoring critical electrical assets. With multiple models, wide power supply range, high accuracy, and flexible sensor compatibility, it ensures timely detection of abnormal temperature rise, reducing maintenance costs and preventing failures. Its standard MODBUS-RTU interface simplifies integration into existing monitoring systems, making it an ideal choice for both new installations and retrofit projects.
