YT-XDN/SW series switch quantity acquisition module

Product Features

A device that can collect and input/control the output of switch signals, and collect the switch signals to a computer or send relevant instructions through the RS-485 bus to control the relevant status of switches through modules. It can also communicate in pairs through the RS-485 bus to remotely control the relevant status of switches. The RS-485 bus is completely isolated from switch quantity acquisition and control, with 600W lightning and surge protection function. It adopts Modbus protocol, which has good universality and can be easily integrated with other systems. Customers can also customize relevant protocols according to their individual needs, which is convenient and flexible. The communication line adopts RS-485 bus, which supports parallel use of multiple modules, making it easy to expand the system and has good scalability.
