4-way i/o module can achieve wireless transmission in real time,the relay output of receiver module is connceting with on-off input of the transmitter relay output.in other words,when the input of the transmitter switch on,the corespond relay output will be on at the same time.when the input of the transmitter switch off,the corespond relay output will be off at the same time.all channels are independent.no program,no wires,users can remote control switching.this product is widely-used in industrial controller,wireless monitoring,waterworks automation and other projects.

1、power indicator-pwr：power on

2、data indicator-t/r：flashes once per second, indicating that the module is operating normally

3、running lights-run：the indicator flashes when the module transmits/receives data each time

4-7：switch output status indication d1-d4：the indicator light is on, indicating that the corresponding output channel is closed, otherwise it is disconnected

2、dip5-8：working mode choosing  

remark：

    *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);

    *in timing mode, one must be the master and the other is the slave

    *it should be effect by re-power on the module after changing the dip position.

1、install the antenna to the module.

    2, in accordance with the use of demand, according to the above instructions set the dip switch, connect          the corresponding switch input, switch output device.

    3, connect the power (12-30v), turn on the power switch, the power requirements of the output current needs        reach more than 500ma.

    4, at this point, the input of module can control the output of another module .

    5, the module is two-way transmission, that is, a module can as an input ,at the same time, can also be            used as a controlled output, and vice versa.

    6, within the same remote control distance range if user using more than two sets of remote control system,        one should use a different operating frequency to avoid mutual interference.

working mode

1、triger mode

       when on-off input status changed,it will triger i/o module to send the local status information. this          mode has fast speed,can be in real time.only when input status changed,then will send the signal,the            energy consumption will be low. 

   2、timer mode

      at this mode, there should be one master and one slave module. the master will

      synchronize with the slave every 1s, means the master will transmits its condition to slave every 1s and       the slave will feedback its condition to master every 1s. if the time master cannot synchronize with           slave reaches at 3s, all contacts will disconnect. they connects until the master is synchronizing with         slave again. there will be 1s transmission delay at this mode.

   3、collecting mode

      at collecting mode, dip8(transmitting mode), dip7(master/slave mode) and dip5(repeater/feedback mode) are       all invalid. at this mode, module works as a modbus slave, it can not transmit data actively. master can       be a pc connecting with a wireless data module or other data terminal. data terminal sends modbus rtu

      command and requests slave feedback collection condition or control slave’s on-off output. slave’s id         can be 1 to 254.

  4、feedback/repeater mode

     at feedback/repeater mode, receiver will retransmit the command it received and make it reach longer            distance. it functions as a repeater. the transmitter will output related on-off condition on its output        com after receiving retransmitted command, meanwhile, the output indicator will be on/off. its output          condition will be the same with its input condition. if receiver didn’t receive the command, it will not      retransmit, feedback will fail. master’s output condition will be not the same with its input. this            function can monitor receiver’s output results.if the user is not familiar with the product and is            unfamiliar with the method of use, all code switches should be pull to the on position to test.

kyl-812 other application

kyl-812 can work with same series i/o module: kyl-813 or kyl-818 etc,to reach the function of centralized control,and centralized output (please indicate to sales when you set the purchase order).please look the below diagram as example:
