16DO Module 16 channels Digital Isolated Output Module NPN Transistor Open Collector Output Module RS485 MODBUS RTU

Product Introduction

1. Product Overview

The MBSL16DO module is a 16 digital isolated output (NPN transistor open collector output) module, which is output through an isolated RS485 interface.

The power supply of the module and the RS485 communication electrical signal are isolated from each other, which effectively suppresses various types of series mode and common mode interference, and also ensures the stable and reliable operation of the module.

1) The module uses RS485 MODBUS RTU standard communication, can be networked with the host computer configuration software, PLC, industrial touch screen, etc., with communication status indicators.

2) The module complies with industrial standards. Signal control, power supply, and RS485 communication electrical signals are isolated from each other.

3) The communication circuit has lightning protection, anti-interference design and power polarity protection.

4) RS485 communication signal output interface has dual protection of overvoltage and overcurrent.

5) The module has automotive-standard hardware and software dual watchdog timers to ensure that the module will never crash and work stably and reliably.

6) Output disconnection protection. When there is a 485 network interruption and the machine does not receive the data sent by the master station within the set time, the module will automatically disconnect the output, thereby automatically protecting the safety of the field equipment.

7) The communication format can be set by software.
