Any questions, please contact us at the above mentioned ways. KYL-812 wireless ON-OFF input and output module is a kind of wireless transmission equipment with 4-channel DI and 4-channel relaying DO. I. The Function of KYL-812 With 4 channel ON-OFF DI and DO, KYL-812 can transmit data timely. The ON-OFF condition of the transmitting equipment can be output timely to 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. The following is the schematic diagram of the ON-OFF transmission. Schematic diagram II、Features of KYL-812 With 4-channel coupler isolated inputs, KYL-812 has high reliability and stability. 4-channel relay causes dry contact output, contact current is 30V 1A. 4-channel 5V power supply causes voltage output. Use with wireless data transmission module whose transmitting distance is 2-3km. Working frequency: 433MHz (400-470MHz are also available); RF power: 500mW; Receiving sensitivity: -120dBm Receiving current: 30mA; Transmitting current: 300mA Power supply: DC 9-15V Size: 82mm*82mm Fax: +86-755-83408785 [email protected] www.rf-data.com Shenzhen KYL Communication Equipment Co., Ltd III. DIP switch definition 1. DIP8：Working mode options: ON—send the input conditions. The module sends the input conditions by 4-channel ON-OFF OFF—send data every 1s or 2s; principal equipment sends out 4-channel input condition to the subordinate equipments (not real-time transmission) 2. DIP7：Principal and subordinate mode choosing under the timing mode: ON—subordinate equipment, OFF—principal equipment 3. DIP6：Sending interval choosing under the timing mode: ON—slow (2s one time), OFF—fast (1s one time) 4. DIP5：No definition 5. DIP1-4：Channels choosing (maximum 16 channels) The following is a channel correspondence table for DIP switch 1-16: DIP NO. Channel DIP NO. No. Channel DIP NO. No. Channel DIP NO. No. Channel No. 1 5 9 13 2 6 10 14 3 7 11 15 4 8 12 16 Note: * Clients generally use the input to change sending mode, DIP7-ON; * To avoid more than two remote control systems working at the same time in the same remote control range, the module for different systems should choose different channels (working frequency); * Under the timing mode, there should be one subordinate equipment and one principal equipment; * The module should be re-powered to get into effect after changing the DIP position.
