1, The module uses high-quality relay, normally open interface Maximum load: AC 250V / 30A, DC 30V / 30A;
2, The use of ultra-small optocoupler, anti-interference ability, stable performance; trigger current only 3mA;
3, The module operating voltage 5V, 12V, 24V to choose from;
4, The 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;
5, Fault-tolerant design, even if the control line is broken, the relay will not work;
6, Power indicator (red), 1-Channel relay status indicator (blue);
7, All interfaces can be directly connected through the terminal leads, very convenient
8, Module size: 6.0cm * 3.0m * 2.5cm (L * W * H);
9, With 4 * 2.0MM diameter fixed bolt holes, easy to install;

Module interface
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.

Package Included:
1*DC 24V 1-Channel 30A Relay Module
