8 PIN In and 8 PIN Out, simple terminal PIN In, may penetrate the dip switch to control, also may penetrate the PC to control. When it's no signal, it demonstrates that the input -output has the photocoupler to be the interface, and prevents the wave form of applied voltage.

RD-800 is a module of 8 points PIN In and PIN Out, including transceiver and receiver module TRW-909HI (902~928MHz),greatly reduce consumer's operational complexity, 8in8out I/O not only penetrates the Terminal to finish wiring easily, but also can permeate the PC control, proceed a pair of many communications.

For duplex wireless RF transceiver product

  • Wireless 8 in-out control box

  • 8 sets of equipment input control

  • 8 sets of equipment output control

  • Effective reducing the connecting cost of the equipment
