Wireless temperature measurement function
Wireless Temperature Receiver:
Each device can be equipped with 1 wireless temperature receiver and 9 (according to customer needs can be expanded to 12) wireless temperature collector, each 3 serial number connected wireless temperature collector is a group.
Dimension: unit(mm)

Installation: 35mm Din rail

Wireless temperature collector:
The specific installation method of the wireless temperature collector is shown in the figure below. Each collector has a temperature-sensing point, and the temperature measured by the collector is the temperature of the temperature-sensing point.
If the collector is placed in the air, the measured temperature is ambient temperature. In order to accurately measure the temperature of the surface of the object, it should be ensured that the temperature-sensing surface of the collector is in close contact with the surface of the object to be measured.

Watch strap wireless temperature collector

Each control device can be equipped with 1 wireless temperature receiver and 9 (can be expanded to 12 according to customer needs) wireless temperature collectors, and every 3 serial numbers connected wireless temperature collectors form a group.
Note: When installing, follow the position marked on the label on the wireless temperature collector. If the installation location is not corresponding, the temperature displayed on the control device from T1 to T12 is not the temperature of the actual location.
The supporting wireless receiving box (rail-mounted installation) must be installed in the handcart room of the circuit breaker, and connected to the control device through a 4-core connecting line (preferably shielded cable). The corresponding connection relationship is as follows:
Wiring method of wireless temperature receiver:
