Product model: YYB-5Input voltage: DC / AC 7V-27VOutput : can control DC or AC load within 30ATime range: 0.1 seconds to 999 minutes, any time adjustableWiring port 1.AC/DC: Input DC/AC 7V-27V2.IN1: Signal input 1 (negative trigger)3.IN2: signal input terminal 2 (negative trigger)4.IN3: Signal input terminal 3 (negative trigger)5.NO: The relay normally opens the interface, the relay sucks and the front dangling, and after the suction and short circuit with COM6.COM: Relay Common Interface7.NC: The relay normally closes the interface, and the relay is shorted to the COM before the suction, the suction and the rear suspensionFunction list: function can be arbitrarily set to buy back, there are instructions to provide, any parameter that can be memorized by failureP--1: Give signal 1, relay 1 will stop automatically when it reaches A; give signal 2, relay 2 will automatically stop when it reaches B, and signal 3 is emergency stop reset signalP--2: Give signal 1, relay 1 is automatically stopped when it is sucked to A time; relay 2 is automatically stopped after the delay time B from the start of the signal to the C time (this function time unit needs to be the same)P--3: After -on, relay 1 is released to A time release, waiting for C time, relay 2 is sucked and released to B time, waiting for C time, relay 1, 2 turns working infinite loopColour:greenMaterial:plasticPackage Contents:2 x relay delay moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
