Contact network switch monitoring terminalIntroduction to Equipment

The contact network switch monitoring terminal is the executor of control commands and the detector of switch status in the contact network switch monitoring system. It is connected to the electric operating mechanism of the contact network switch through control cables, collects the position of the isolation switch, the position of the power supply micro disconnection in the operation box, the operation status of the motor, the local remote status, and the backup power status, and executes remote control commands for scheduling.
The contact network switch monitoring terminal is generally installed in an outdoor installation box or the electric operating mechanism box of the contact network switch. The operating environment is harsh and the electromagnetic interference is strong, so the environmental adaptability of the equipment is particularly important.

FTU-C-Smart adopts industrial grade components with strong environmental adaptability and anti-interference ability, and adds anti-interference filtering circuits in the design process to further enhance anti-interference ability.
