16 Road inputs and 16 outputs Relay Module/PLC Amplifier/MODBUS RTU/RS232+485 Dual Serial Ports - (Color: Without Rail)

Product Name: 16-channel input and output moduleapplication scenario: computer secondary development/industrial equipment/PLC amplification/DC motor drive.Features: 1. Electric voltage: 24V DC, no-load power consumption of the module is less than 2W.2. 8/16 inputs: NPN type or two-wire passive switch.3. 8/16-way relay output: 10A high current.4. Communication interface: RS232 + RS485 double serial ports can be independently controlled.5. Working mode: the default is serial port control mode, which can be configured as PLC amplification mode for the protection and function expansion of PLC output points.6. Practical function: through the wiring of relay, it can be used for the control of forward and reverse rotation and stop of DC motor, and can drive 4/8 DC motors in total (no speed regulation).7. All input and output are isolated by optocoupler, and isolated power supply module is adopted, which greatly enhances the stability.Serial port Protocol: (default communication parameters 9600,n,8,1)read single input port status: 01 01 00 05 07 0D 0Aresponse:01 01 05 01 08 0D 0A(No.5valid Path input)read16channel input port status:01 02 00 00 03 0D 0Aresponse:01 02 03 04 0A 0D 0A(No.3/9/10valid Path input)read Status:01 03 00 01 05 0D 0Aresponse:01 03 01 00 05 0D 0A(No.1path not output)read16route status:01 04 00 00 05 0D 0Aresponse:01 04 80 01 86 0D 0A (The first1/16road closed, others disconnected)write single relay output:01 11 05 01 18 0D 0A (will5road closure)response:01 03 05 01 0A 0D 0A (The first5road closed)write16circuit relay output:01 22 01 08 2C 0D 0A (will4/9road closure)response:01 04 01 08 0A 0D 0A (The first4/9the road is closed and the others are disconnected.)Modify the module address:01 91 00 02 94 0D 0A (change the module address2)response:02 91 00 02 95 0D 0A (the module address is2)modify baud rate:01 92 00 0
