A, product characteristics 1, the 8 circuit photoelectric input; 8 way relay output (with optocoupler isolation). 2, with RS232/RS485/CAN communication interface, convenient cascade (plate is provided with a dial switch can be set to the board address, supports up to 127 board cascade). 3, the relay optional 12V/24V two, Hongfa original relay, durable. The red line is connected and the power "+". 2, RS485 network command format The relay control plate by RS485 or CAN network, through the RS232 control the state of relay board (can also directly through RS485). The command frame with 0X48, 0X3A at the beginning, end with 0X45, 0X44. Byte13 is the first 12 bytes (8 bits and only low). Relay board return input / relay status: 0X01 is closed, 0X00 is disconnected. Write state relay output: 0X01 is closed normally open contact, disconnect the normally closed contact is disconnected; 0X00 normally open contact is closed, the normally closed contact; other values, not change relay status: The command code sample: Read the numbers for 8 input state 1: 0X48,0X3A, 0X01,0X52,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0XD5,0X45,0X44 Numbers for relay board 1 return 8 road input state (Second Road and fifth road closed, the other path is disconnected): 0X48,0X3A, 0X01,0X41,0X00,0X01,0X00,0X00,0X01,0X00,0X00,0X00,0XC6,0X45,0X44 To the number for the relay board 1 Write relay status (road second normally open contacts, the normally closed contact is disconnected; road fifth normally open contacts, the normally closed contact is disconnected; the other path is normally closed contact is closed, normally open contacts disconnect): 0X48,0X3A, 0X01,0X57,0X00,0X01,0X00,0X00,0X01,0X00,0X00,0X00,0XDC, 0X45,0X44 Read the numbers for the relay in 1 (State Road second normally open contacts, the normally closed contact is disconnected; road fifth normally open contacts, the normally closed contact is disconnected; the other path is normally closed contact is closed, normally open contacts disconnect): 0X48,0X3A, 0X01,0X53,0X00,0X01,0X00,0X00,0X01,0X00,0X00,0X00,0XE0,0X45,0X44 Numbers for relay board 1 return 8 relay state (road second normally open contacts, the normally closed contact is disconnected; road fifth normally open contacts, the normally closed contact is disconnected; the other path is normally closed contact is closed, normally open contacts disconnect): 0X48,0X3A, 0X01,0X54,0X00,0X01,0X00,0X00,0X01,0X00,0X00,0X00,0XDF, 0X45,0X44 3, CAN network command format (1) the CAN parameter The baud rate: 250KBPS Frame format: extended data frame Data length: 8 Scope address code is 0X00 to 0XFE, the total can cascade 127 relay board. (3) the CAN message (data) meaning This agreement CAN packet is 8 bytes of data, each byte represents an input / relay status. When the said relay status: 0X01 is closed normally open contact, disconnect the normally closed contact is disconnected; 0X00 normally open contact is closed, the normally closed contact; other values, not change relay status. When the said switch input state: 0X01 is closed; 0X00 is disconnected, other values indicate no change switch input.
