What is it?

This is a simple wireless control system in automation area.

Control room: there is 1 LS-RDIO0808 8-loop I/O module and 3 LS-RDIO8-E Expanders. So there is 32DI32DO on master side totally.

At field: there are 4 slaves at different places, each place 1 LS-RDIO0808 8DI8DO.

The master can control each salve's ON-OFF condition in time.

Why did we make it?

Sometimes it is very hard to wire cable in many projects field, so we considered a wireless solution.

Our wireless modules just instead the signal cable to read remote devices' ON-OFF conditions and control remote ON-OFF.

What makes it special?

wireless solution will save cost and save time, keep in time monitoring and real time control

don't need internet, communication in-time, delay time short(in mS)

this kinf of application no need program, easy to install

system expandable, don't need to take off installed items if system expand, directly add more
