4 photoelectric isolation input, dry node input switch, not with voltage. 4 10A high current relay output. Using RS485 interface, protocol used in industry of the popular MODBUS RTU protocol. It can be easily embedded in the RS485 bus. A RS485 bus can connect 32 module, set the address parameters such as software. The parameters stored in the EEPROM. Provide control sample source code. Standard guide installation industry. Aspiration design. The electricity is sucked by accident. MODBUS Standard Test software. Wide power supply 9-24V power supply.
A wiring instructions,
GND-------- NO1---- the first group of normally open relay
+12V-------12V COM1--- first group relay common
485A-------RS485 NC1---- is the first set of relay normally closed
485B-------RS486 negative group NO2---- second normally open relay
The first group IN1-------- switch input COM2---- second group relay common
IN2-------- second group NC2---- second group switch input and relay
IN3-------- third group NO3---- third group switch input and relay normally open
IN4-------- fourth group COM3---- third group switch input and relay common
NC---------, do not use the NC3------- third group relay
NO4------- fourth sets of normally open relay
COM4------ fourth group relay common
NC4------- fourth group relay
A software protocol,
The baud rate is 9600, a start bit, 8 data bits, one stop bit, a test is invalid. The default address 0x01. In agreement with the MODBUS RTU specification.
Detailed instructions (address 0x10)
1, read the switch input.
Send instruction format: Address (1 bytes) + command (one byte) + register address (two bytes) + data domain (two bytes) +CRC checksum (two bytes).
Data format: return address (1 bytes) + Command + (one byte) returns the number of bytes (1 bytes) + return data (one byte) +CRC check code (two bytes)
Send: 0x01,0x02, x00,0x20,0x00,0x04,0x78,0x03
Returns: 0x01, 0x02, x01,0x0F, 0xE1,0x8c
Return to the 0x0F, this module only low 4, only about four low. From first to fourth respectively, said switch input INPUT1 to INPUT4 state, when there is a switch input
When the signal, the corresponding bit is 0, if the first switch quantity input, no other way switch input, this value is 0x0E.
2, the control relay output.
2.1 a single control relay (assuming module for 0x01)
The first road 0x01,0x05,0x00,0x10,0xFF, 0x00,0x8D, 0xFF
Second 0x01,0x05,0x00,0x11,0xFF, 0x00,0xDC, 0x3F
Third 0x01,0x05,0x00,0x12,0xFF, 0x00,0x2C, 0x3F
Fourth 0x01,0x05,0x00,0x13,0xFF, 0x00,0x7D, 0xFF,
First off road 0x01,0x05,0x00,0x10,0x00,0x00,0xCC, 0x0F
Second 0x01,0x05,0x00,0x11,0x00,0x00,0x9D Road, 0xCF
Third 0x01,0x05,0x00,0x12,0x00,0x00,0x6D Road, 0xCF
Fourth 0x01,0x05,0x00,0x13,0x00,0x00,0x3C Road, 0x0F
The 2.2 time all relay operation
Open all the 0x01,0x0F, 0x00,0x10,0x00,0x04,0x01,0x0F, 0xBF, 0x51
Close all 0x01,0x0F, 0x00,0x10,0x00,0x04,0x01,0x00,0xFF, 0x55
The one or two road, three or four road 0x01,0x0F, 0x00,0x10,0x00,0x04,0x01,0x03,0xBF, 0x54
The one or two road, three or four road 0x01,0x0F, 0x00,0x10,0x00,0x04,0x01,0x0C, 0xFF, 0x50
3, read the state of the relay output
Send instruction format: Address (1 bytes) + command (one byte) + register address (two bytes) + data domain (two bytes) +CRC checksum (two bytes).
Data format: return address (1 bytes) + Command + (one byte) returns the number of bytes (1 bytes) + return data (one byte) +CRC check code (two bytes)
Send: 0x01,0x01, x00,0x10,0x00,0x04,0x3c, 0x0c
Returns: 0x01, 0x01, x01,0x00,0x51,0x88
Returns 0x00, the state of the relay output, 0 off, 1 pull. This module only low 4, only about four low.
4, set the module address
The device address is changed to 01: 0x00,0x06,0x00,0x01,0x00,0x01,0x18,0x1b
This product can connect to the PLC, we know that PLC MODBUS supports the RTU protocol, the test software Modbus Poll test MODBUS communication.
