HR-804 wireless ON-OFF relay DO module I/O module

HR-804 4 ways wireless I/O module, ON and OFF transmission module ,input and output module

HR-804 wireless ON OFF input and output module is a wireless transmission equipment with four 4 way DI and 4 way relay DO.

I.Function and feature

4 channel ON-OFF DI and DO transmitting timely. The 4 channel ON-OFF condition for the transmitting equipment can be output timely at the receiver equipment. That is the ON-OFF condition for the transmitting equipment is shut down, while the ON-OFF condition will be shut down at the receiver equipment; and the transmitting equipment is disconnect, while the receiver equipment will disconnect.

1.4 channel coupler isolated inputs, high reliability and stability.

2.4 channel relay dry contact output, contact current is 30V 1A.

3.4 channel 5V voltage output.

4.collocate wireless data transmission module with 2-3km.

Working frequency 433MHz(400-470MHz);

RF power:500mW;

Receive sensitivity:-120dBm

5.Receive current:30mA; transmitting current: 300mA

6.Power supply:DC 9-15V

7.TTL connector

7.Size: 82mm*82mm

II. Switch definition for dialing code

DIP8:Working mode choosing:

ON:send the inputting conditions. The module will send the inputting conditions of the 4 channel ON OFF

OFF:send timely every 1s or 2s; principal equipment will send the 4-channel input condition to the subordinate equipment (non-realtime transmission)

DIP7:Principal and subordinate mode choosing under the timing mode:

ON:subordinate equipment, OFF:principal equipment

DIP6:Sending interval choosing under the timing mode:

ON:slow(2s one time), OFF:fast(1s one time)

DIP5:No definition

DIP1-4:Channels choosing (max 16 channels)

Note:

* Users generally use the inputting change sending mode, DIP7-ON;

* To avoid more than two remote control systems working at the same time in one remote control range, the module for different system should choose different channel (working frequency);

* Under the timing mode, it should be one subordinate equipment, and

one principal equipment;
