Feature

Isolation 1-Channel high-power relay control module, select the high signal trigger, only need 3mA current can drive control capability of 30A relay pull.The module uses high-quality relay, normally open interface Maximum load: AC 250V / 30A, DC 30V / 30A;
The module uses high-quality power relay, ultra-small package optocoupler, high-power high-voltage transistor, red and blue signal indicator, double-sided PCB board, cloth board to consider a comprehensive, stable performance can be widely used in a variety of power control .The Module operating voltage 5V, 12V, 24V to choose from;
Relay high level pull, the module contains current limiting resistor, high level can be DC +, can also be single-chip I / O port set high;
Fault-tolerant design, even if the control line is broken, the relay will not work;Power indicator (red), 1-Channel relay status indicator (blue);, All interfaces can be directly connected through the terminal leads, very convenient; Module size: 6.0cm * 3.0m * 2.5cm (L * W * H); With 4 * 2.0MM diameter fixed bolt holes, easy to install;

Description

Module control: 4 interfaces, all interfaces have terminals, user-friendly wiring;
1, DC +: External DC power supply negative (5V, 12V and 24V modules available)
2, DC-: external DC power supply negative;
3, VERF: photoelectric isolation control terminal reference ground, this signal should be connected to the user control panel power supply negative;
4, CH1: relay control interface, high level (relative to VERF) corresponding relay pull.

Note: the isolated relay module in order to adapt to the electromagnetic environment is relatively poor or relatively high signal requirements of the occasion, if you want to achieve a complete isolation effect, the user control panel power supply (that is connected to the VERF reference power) and the relay module power supply (DC + / DC-) should be separated, if the two power supply shared ground, then the effect is not fully isolated, then the user can use the standard relay module.

Relay output: 3 interfaces, all interfaces have terminals;
1, NO: relay normally open interface;
2, COM: relay common interface;
3, NC: relay normally closed interface;

Package Included:
1*DC 5V 1-Channel 30A Relay Module
