WINSUN Manufacturers selling 4 12V relay module photoelectric isolation optocoupler PLC control

4 road 12V photoelectric isolationRelay moduleProducts alreadyA large number of applications to industrial applications, stable performance.

PCB size 7Simm * 60MM * 21mm.

4 road 12V photoelectric isolationRelay moduleTwo control level modules can be set arbitrarily high and low.

(1). High quality PCB, FR-4 material, double marked, spray tin, quality common PCB can ratio, a thicker line, safe and stable performance.

(2) welding technology is not the same. In strict accordance with the IPC-610 standard for welding welding. And there will be no dross, tin hole, refusing phenomenon such as welding, surface cleaning clean, only for higher quality.

(3) the use of components more sophisticated. Each component is carefully eamined and qualified.

(4). The finished product inspection is more strict. After welding products, all through 100% function test and stability test, let you use more at ease!

Equisite workmanship,Stable performance.

Main features:

1Each road relay has the working status of the LED lamp indicating relay.

2Optocopler isolation makes the system more secure, more stable anti interference ability;useDouble couplerCan makeTwo control modes with high and low level,Compatible with various NPN and PNP outputs for PLC etensions.

3With the diode continued current protection circuit, the service life is longer.

4Double power users can be used according to the needs, through the short circuit cap to switch, select the power supply is more fleible and convenient to use.

5The relay power supply has the connection terminal and the DC power socket (5.5mm*2.1mm) two kinds of interface forms, the use is more fleible, is more convenient.

6The relay output contact with double - line, can withstand large current more secure.

7,With fourWith the positioning hole 3.

8, strict inspection, to ensure quality.

Use:

1, single chip microcomputer control;

2, PLC control epansion;

3, the field of intelligent industry;

4, home intelligent control.
