8-channel IO Controller Industrial Iot Data Acquisition Device DAQ RS485 Modbus RTU Transceiver

I. Introduction

This 8-way ON-OFF module is to transmit the ON-OFF condition to a remote place wirelessly in time.

When here the switch condition is ON,

the output in the remote place is ON.

When the local switch condition is OFF,

the other terminal is OFF.
