Chapter 1 Product Introduction

I. Overview

MB16DO 16-channel relay output module, the relay can be controlled through MODBUS bus, the control interface is isolated RS485, adopts Modbus-RTU communication, and directly adapts to PLC, DCS and various domestic configuration software, etc.

Relay output, power supply, and RS485 communication electrical signals are isolated from each other, effectively suppressing various series-mode and common-mode interference, and ensuring the module works reliably.

2. Features

1. Using Modbus-RTU protocol, it can be directly adapted to PLC, DCS and various domestic configuration software.

2. The relay output, power supply, and RS485 communication electrical signals are isolated from each other.

3. The RS485 communication signal output interface adopts double overvoltage and overcurrent protection.

4. Power polarity protection.

six. Module indicator light and switch function description

1. POW/SET; module working status indication

A. The green light is on: the module is working in the running state.

2.TXD/RXD: communication status indication

A. Green light is flashing: the communication has received data B. Red light is flashing: the module is sending data

C. The green light is always on: the communication RS485 lines connected to DATA+ and DATA- are reversed or the wiring is broken.

3. Reset switch on the right side of the module

1) When the communication parameters (module address, baud rate, check digit) are unknown or the communication parameters are set incorrectly, and the communication with the module cannot be established, the solution is to reset the communication parameters; find the reset switch on the right side of the module, and use Press and hold the module switch with a paper clip, and after 5 seconds, the green indicator [POW] of the module will turn off and turn on again. At this time, release the reset switch, and the communication parameters have been reset. At this time, the communication parameters of the module have been reset.

2) Communication parameters after reset: address: 1, baud rate: 9600bps, parity bit: none.

Reset communication parameters

1) Why reset communication parameters:

a) The user forgets the communication parameter settings and cannot communicate with the module.

b) The user has mistakenly set the communication parameter settings and cannot communicate with the module.

2) How to reset communication parameters

a) Press and hold the tact switch on the right side of the module for more than 5 seconds until the module [POW/SET] red indicator lights up, then release the pressed tact switch.

b) After the module is powered off and powered on again, the communication parameters have been reset to default values.

Example of setting communication parameters

1) Current communication parameters: address: 1, baud rate: 9600bps, no parity bit

2) Communication parameters that need to be set: address: 2, baud rate: 19200bps, no parity bit

3) To organize the written commands, use the 0x10 function code to organize the commands.
