Communication interface and protocol:
1. Transmission method: RS485
Communication protocol: Modbus. CJ/T188-2004
Supply voltage: DC12V
Transmission distance: The maximum transmission distance is not more than 1200m, the maximum number of meters is not more than 64 (recommended maximum transmission distance is not more than 800m, the maximum number of meters is not more than 32, and the transmission line uses RVSP 1.5m².) The actual transmission distance and signal, power The cross-sectional area and length of the line are related to the number of modules
Wiring sequence: red wire-DC12V, white wire-GND, yellow wire RS485A, blue wire RS485B
Module power consumption: ≤10mA
2. Transmission method: MBUS, C-MBUS
Communication protocol: CJ/T188-2004
Transmission distance: The maximum transmission distance is not more than 2000m, the maximum number of meters is not more than 256 (recommended maximum transmission distance is not more than 800m, the maximum number of meters is not more than 32, and the transmission line uses RVSP 1.5m²)
The actual transmission distance is related to the cross-sectional area and length of the signal, power cord, and the number of modules carried
Wiring sequence: red and yellow wires, regardless of polarity
3. Transmission method: pulse output
Pulse output interface-5 pin round head interface, protection grade IP68
Pulse rate, pulse width can be set
Set the port communication protocol RS232
a. Red positive and black positive b. Red positive and black negative C. Red wire output magnet revolutions d. No output
The red and black lines can be set with different magnifications and pulse widths
