4 channel relay output I/O controller module

Model: WS-IOB-4CH

Product Description

IOB-4CH is a simply and electronic I/O board which have 4 channel relay output and a 7-PIN input interface, very easy to integrate with other control board. The controller adopts HID technology, with double-isolated 4-channel relay output, plug and play, no protocol, no need any drivers. It is a cheap and good quality accessory for other intelligent controllers.

Applications:

Switch control smart home,hotel intelligent switch,hotel intelligent electrical control,intelligent greenhouses, Shopping smart switch,the company plant intelligent switch,timer management cafes,karaoke OK timing control,Physical networking,industrial control equipment,testing equipment power control , street management,intelligent management,centralized power management.

Features:

1. Using of high-quality relay,Normally open relay contacts maximum load:AC 250V/10A,DC 30V/10A;

2. Using of high-withstand voltage transistor, strong driving ability, stable performance, trigger current of 3mA;

3. Working voltage 5V/12V(for options, please note the voltage you need when you place an order)

4. User can select the relay control level ,it can be high-level pull or low-level pull; the module contain limited flow resistance, Trigger signal can be DC power supply positive or negative, also can be Microcontroller I/O port set high or low;

5. Fault-tolerant design, if the control line is broken, the relay will not operate;

6. The power indicator (red LED), 4-channel relay status indicator(blue LED);

7. The interface humanization design, all interfaces can be drawn through terminals connect directly, very convenient;

8.With two fixed bolt holes for easy installation
