16 Channel 12v Relay Module with Optocoupler Low Level Trigger Expansion Board

Descrição de 16 Channel 12v Relay Module with Optocoupler Low Level Trigger Expansion Board

It is 16 Channel Isolated 12V 10A Relay Module, each relay can individually switch on/off by an opto-isolated digital input, Standard interface can be directly connected with microcontrollers and be controlled directly by a wide range of microcontrollers such as , AVR, PIC, ARM, DSP, etc., very convenient.Equipped with high-current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; Trigger current of opto-isolator: 5mA.RELIABLE: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling isolation, triggering more reliable, more stable.EASY to INSTALL: Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation.With indication LEDs for Relay output status. The working status indicator lights are conducive to the safe use.Input Interface:DC+:connect to power positive (according to the relay voltage range)DC-: connect to power negativeIN: relay module trigger pin (high or low level trigger Optional)Relay Output:Normally Opened (NO) : normally open pin of relay. NO pin is not connect to COM pin when relay off.NO pin is connect to COM pin when relay on;Common pin (COM) : Common pin of the relay;Normally closed (NC) : normally close pin of relay.NC pin is connect to COM pin when relay off.NC pin is not connect to COM pin when relay on.Colour:Photo ColorMaterial:ABSPackage Contents:1 * Relay ModuleOnly the above package content, other products are not included.Note: Light 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.
