KNACRO DC 05V 3-Channel 30A Relay Control Module Bi-Directional Isolated Control Module High/Low Level Trigger (DC 24V, 10A 16-Channel)
- Bidirectional isolation 3-Channel high-power relay control module, select the high or low 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;
- The user can select the relay control level, can be high level pull, it can be low level pull; module with current limiting resistor, you can directly use the power supply positive and negative control, you can also use the microcontroller I / O Mouth control
- Fault-tolerant design, even if the control line is broken, the relay will not work;Power indicator (red), 3-Channel rela

VREF: photoelectric isolation control terminal reference ground, -If a high level control is used: this signal should be connected to the negative of the user's control panel power supply; -If low level control is used: this signal should be connected to the positive terminal of the user's control panel power supply;
CH1-3: relay control interface, -If VREF is connected to the power supply negative: When this port is high level (relative to VREF), the corresponding relay is engaged; -If VREF is connected to the power supply positive: When this port is low level (relative to VREF), the corresponding relay is engaged;
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: 9 interfaces, all interfaces have terminals, user-friendly wiring1, NO1-NO3: relay normally open interface.
2,
COM1-COM3: relay common interface.
3,
NC1-NC3: relay normally closed interface.
Package Included: 1*DC 05V 3-Channel 30A Relay Control Module
