Feature:1. 8 Channels multifunction infrared controller, each channel triggers independently and delays independently, will not interfere with each other.2. 4 Functional modes: inching, delay (2/10/60/600/3600 seconds), selflocking, interlocking (the functional mode is set by the solder pad on the board).3. Low pulse control (GND control connected with the button or IO interface controlled by single chip microcomputer).4. There are 5V and 12V types available, you can choose by your needs.5. Remote control distance of 8‑15 meters (receivers sensitive >= 0.5mw /m2).Specification:Condition: 100% Brand NewItem Type: RelayMaterial: Plastic Optional Voltage: 5V, 12V Working Current (DC 12V): Standby current 8MA1 relay operating 37MA2 relay operating 66MA3 relay operating 94MA4 relay operating 122MA5 relay operating 150MA6 relay operating 178MA7 relay operating 206MA8 relay operating 232MA"Inching", "self-locking", "interlocking" and "delay" four functional modesInfrared Receiver: VS1838(or IC compatible)Infrared Codes: NEC codesRemote Control Distance: 8-15 meters (receivers sensitive >= 0.5mw /m2)Input Control Interface: 5V TTL level, NPN triggered, 0.2-2 seconds low pulseMaximum Load Capacity of Relay: DC 1-110V/5A;AC 85-265V/6ABattery: Button battery, CR2025, 3V (Not included).Package List:1 x 8 Channel Infrared Relay1 x Remote Control
