Model: RD-800

RD-800 can be used as industrial controls and provide wireless control interface. RD-800 offer 8 sets of control signal input and 8 sets of equipment control output. It´s only needed several simple wiring steps and then change to a wireless control environment. It can effectively reduce the cost of connecting equipment.

Product Block Diagram

Chart 1 RD-800 Product Block Diagram

RD-800 has the complete RF receiving and transmitting circuit and interface, Chart 1 is the function block diagram of RD-800, the main components are as follows, DSP processor, circuit of RF frequency, memory, power and system connector, all can connect outer antenna. When through system connector is able to link 8 sets control signal input port and 8 sets equipment control output port.

In Chart 1, inside the red line frame is the each component part of the main board of RD-800. The outside of red line is outer interface. The narrow band of RD-800 main board has finished all the function of wireless control. Include RF specification and the code of RF data, regulation frequency indication. Additionally, the main board also include: 8 sets control signal input port and 8 sets equipment control output port. LED light instruction. The follows we will separate to introduce each part function of main board and outer interface.

Introduction of Each Function

DSP Processor
DSP processor finished all signals handle function of RD-800, including receiving and transmitting RF data, LED light instruction, and judgment of the button.
Circuit of radio frequency
The circuit of radio frequency offers the pass way of receiving and transmitting of 922~928MHz. Including receiving circuit, transmitting circuit, frequency compose the circuit.
Memory
The memory is mainly used in storing the present working frequency and RF transmitting speed.
Circuit of the power
Circuit of the power offered AC 24~28V or DC 20~28V input in power supply.

Indication Position	Item	Description
1	AC/DC Input	Outer power input
2	Controlled Signal Input	Provide 8 sets signal input
3	Device Controlled Output	Provide 8 sets signal output
4	Antenna	The position for antenna insert.
5	Link key equipment	Link equipment and self-test function keys
6	Track	Put in the position of aluminum track

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-V4B (922~928MHz),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.
