This relay is stable, durable and compatible. Specification: Type: 12 channel remote control switch Output current: 20A Static working current: ≤6mA Output voltage: AC 125V / DC 14V Working voltage: 12V Battery type: 1 x 23A/12V battery(not included) Working frequency: 315 433MH Remote control distance: Approx. 200-500M Operating temperature: 40°C ~ +80°C Receive Sensitivity: ≥105dBm Working mode: Momentary, Self-locking, Interlock Relay size: Approx. 10 x 8 x 2.5cm / 3.93 x 3.14 x 0.98inch Remote size: Approx. 12 x 5 x 1.5cm / 4.72 x 1.96 x 0.59inch Weight: 243g Working mode: Momentary: Press every button on the switch, and the corresponding relay is connected. Release the switch, the corresponding relay is closed. You can only connect a relay at a time. Interlock: Press every button on the switch, and the corresponding relay is connected. And then press the other button on the switch, the corresponding relay is connected. The other relay is closed. You can only connect a relay at a time. Self-locking: The same button control a relay. Press once means opening, press again means closing. Two independent control. Working mode switching & Switch pair instructions: Momentary: Learn from the "3" button on the switch, and all 12 relay will jog. Press the 1 button of the switch, and the corresponding A1 relay will open, release it, A1 relay will close. All relays are for this mode of work. Interlock: Learn from the "6" button on the switch, and all 12 relay will interlock. Press the "1" button of the switch, and the corresponding A1 relay will open and hold, the other 11 relay close, press the "2" button on the switch, the other 11 relay close, A2 relay will open and hold, working successively. Self-locking: Learn from the "9" button on the switch, and all 12 relay will self-lock. Press the "1" button of the switch, and the corresponding A1 relay will open and hold, press the "1" button again, A1 relay close. The way it works is not related to other buttons. All 11 relay are working in this way. Learning method: Press the learning key on the receiver. Press the button on the switch to learn after the buzzer sound. It means successful learning after the receiver has the signal and the buzzer sound. Clearing method: Long press to learning button on the receiver about 10 seconds until the buzzer sound. The stored information is successfully cleared. Package List: 1 x 12 Channel Relay 1 x Remote Controller
