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

Opis produktu: 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.
