Puyu 4 Channel Relay Control Module / Expansion Board / Optocoupler Isolation / High Level Trigger (12V)

EAN: 0543212349272

UPC: 543212349272

Accessory Power

the module uses genuine high-quality relay, normally open interface Maximum load: AC 250V/10A, DC 30V/10A;
fault-tolerant design, even if the control line is broken, the relay will not operate
Note: isolated relay module is designed to adapt to the electromagnetic environment is relatively poor or relatively high signal occasions, if you want to achieve complete isolation effect, the power of the user control panel (the connection VERF reference power supply) power supply and relay module (DC + / DC-) should be separated, if these two power of, if not completely isolated from the effects, the user can choose more economical standard relay module.
Relay outputs: 12-wire interface, all interfaces are terminal block, user-friendly wiring
1, NO1 - NO4: relay normally open interface, the relay becomes vacant before pull shorted with COM 2, COM1 - COM4: public interface relay 3, NC1 - NC4: relay normally closed interface, the relay shorted together with COM, pull vacant

The isolated relay control module description          Isolated 4-way relay control module, high signal to trigger only 3mA current can be driven control 10A relay module with genuine quality power relay, the industry's top ultra-small package optocoupler, high-power high-voltage transistors, red, blue signal lights, military grade double-sided PCB board, cloth board to consider a comprehensive, stable performance, can be widely used in a variety of power control types of occasions.             One module description 1, the module uses genuine high-quality relay, normally open interface Maximum load: AC 250V/10A, DC 30V/10A; 2, the use of ultra-small opto-coupler of the industry's top quality, anti-interference ability, stable performance; trigger current is only 3mA; The module operating voltage have 5V, 12V, 24V are available; otherwise to 1, 2, 4, 8 modules to choose from; Relay high pull-in module with limited flow resistance, high DC + can also single-chip I / O port is set high; 5, fault-tolerant design, even if the control line is broken, the relay will not operate; 6, the power indicator (red), 4-way relay status indicator (blue) 7, interface design, user-friendly, all interfaces can be drawn through terminals connect directly, very convenient 8 module size: 7.5cm * 5.0m * 2.0cm (L * W * H) 9, has four fixed bolt hole for easy installation Second module interface Module control terminal: 7-wire interface, all interfaces are terminal blocks, user-friendly wiring 1, DC +: external DC power supply negative (there is 5V, 12V and 24V modules to choose from) 2, DC-: an external DC power supply negative 3, VERF: optically isolated control terminal reference ground, this signal should be connected to the negative terminal of the power supply in the user control panel 4, CH1-CH4: relay control interface, high (relative to VERF) corresponding relay
