8CH 433M Bidirectional IO Controller Point-to-Point Feedback Remote Controller Relay Swicth Module for Garage Security JH2

This is a wireless remote control switch with feedback function, no configuration required, as long as the transceiver ''Frequency and ID'' settings are consistent, it can be controlled. With feedback function, the LED indicator on the transmitter will indicate the switch status of the receiver. Application: Smart Home; Home Automation; Identification system; Remote Motor Control System; CCTV Camera PTZ Control; Security system; LED dot matrix screen; Ship remote control system; Farm remote gate control system NOTE: To install the antenna, remove the top cover of the housing. NOTE: When using two transmitting devices at the same time, the frequency or ID number cannot be the same NOTE: When using two receiving devices at the same time, the frequency or ID number cannot be the same Transmitter : 1 Working voltage: DC 12V (8-30V) 2 Working current: 12-30MA 3 Input channels: 8 channels, low pulse trigger (NPN) 4 Transmit power: 22dBm 5 Working frequency band: 425~455MHz (can be set by DIP switch) 6 The farthest transmission distance in the open field: 2 kilometers Receiver: 1 Working voltage: DC 12V (11-15V) 2 Working current: 12-260MA 3 Output channels: 8 channels 10A relay output 4 Working frequency band: 425~455MHz (can be set by DIP switch) 6 The farthest transmission distance in the open field: 2 kilometers 6 Working mode: Momentary(Jog),Self-locking,Interlock, Delay (can be set by DIP switch) 7 Maximum load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDC The first use process: 1 Confirm that the frequency and ID of the receiver and transmitter are the same 2 Power on the receiver first, the PWR light is on 3 Power on the transmitter again, the PWR light flashes, and the PWR light on the receiver flashes at the same time, indi
