Puyu 1 Channel 30A Relay Module / Expansion Board / Optocoupler Isolation / High Level Trigger / 12V

EAN: 0543212349357

UPC: 543212349357

Accessory Power

the module uses genuine high-quality relay, normally open interface Maximum load: AC 250V/30A, DC 30V/30A
the module operating voltage 5V, 12V, 24V are available
Relay high pull-in module with limited flow resistance, high DC + can also single-chip I / O port is set high
the power indicator (red), 1 relay status indicator (blue)
Isolated 1-way high-power relay control module, the use of a high-level signal to trigger only 3mA current needed to drive the control capacity of 30A relay, genuine high-quality power relay module, 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

The 30A relay control module description          One module description the use of ultra-small opto-coupler of the industry's top quality, anti-interference ability, stable performance; trigger current is only 3mA fault-tolerant design, even if the control line is broken, the relay will not operate; interface design, user-friendly, all interfaces can be drawn through terminals connect directly, very convenient module size: 6.0cm * 3.0m * 2.5cm (L * W * H) 9, with four 2.0 mm diameter fixed bolt hole for easy installation Second module interface Module control terminal: 4-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 CH1: relay control interface, high (relative to VERF) corresponding relay 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 distinguished If both of power, of less than completely isolated from the effects of the user can choose a more economical standard non-isolated relay module. Relay outputs: 3-wire interface, all interfaces are terminal blocks 1, NO: relay normally open interface, the relay becomes vacant before the pull shorted with COM 2 COM: public interface relay NC: relay normally closed interface, the relay shorted together with COM, pull vacant
