4Road isolation input/Output/4RoadPWMOutputRS485Relay module，Smart home networking control module。

Application scenario：

Industrial control terminal products

Intelligent home networking control system

Internet of Things intelligent equipment

Communication instruction useModBusStandard Universal03And06Function Code。

03The function code is to read data from a single or multiple registers.

06Function Code is data written to a single register

Here are some examples of communication instructions：(The actual instructions are subject to the module manual.)

The above instructions are all commonmodbus-rtuAgreement。

1、4Road switch input ，Each input is isolated with optical coupling.，The place where the input signal is received，Not associated with the module，If the signal ground of the input device is combined with the power supply of the module, it can beSGNDWithGNDConnection。DC voltage of input signal3-24V.Can be read out four times。

2、4RoadPWMOutput，Every wayPWMThe output is independent，The output range is0.0-100.0%，Adjusting step0.1%(Output frequency5Hz-2000Hz).Adjustable output frequency，The default is50hz。

3、 4Road relay output，The maximum load that can be borne by each relay output is10A，4Road5VRelay can control one-way output switch separately，You can also control the output switch together.，Can read the current state of the four-way relay。

4、Purchase this module to provide PC software for user verification module and debugging others485Communication equipment。

5、This relay module is connected at most without a repeater.30Network Communication，If you connect a repeater, you can connect it.100-200Network Communication。

6、This module has power supply anti-reverse protection，Input power supply provides two input methods，Input DC power supply12V/1A.

7、This module has the function of restoring factory settings.，When the user forgets the communication baud rate or device address, the factory default parameters can be restored by restoring the factory settings function.。Factory default baud rate is9600bps，Device address is1。

8、This module can be directly connected to the generalPLCOn equipment or other industrial computers and other platforms，Fully open to international standardsmodbus-rtuProtocol development，Each relay and input switch are represented by two bytes.，Not the custom of other storesmodbusAgreement，State return or control output is one register usedbitTo represent。

In addition, the status return can read the current status of the four-way relay and the status value of the four-way input switch at a time.，Can also be read all at a time8Status value（4Road Relay+4Road input switch value）。Please refer to the module manual for specific operation agreement.。
