Description

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;.

The module uses high-quality relay, normally open interface Maximum load: AC 250V / 30A, DC 30V / 30A; The use of ultra-small optocoupler, anti-interference ability, stable performance; trigger current only 3mA; 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; 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 control: 4 interfaces, all interfaces have terminals, user-friendly wiring; DC +: 5V+; DC-: 5V-; VERF: photoelectric isolation control terminal reference ground, this signal should be connected to the user control panel power supply negative; 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-wire interface, all terminals have terminal blocks NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction. COM: relay common interface NC: relay normally closed interface, shorted to COM before the relay is sucked, suspended after suction;
