16DI/16RO 16-channel Digital Isolated Input and 16-channel Relay Isolated Output RS485 MODBUS Module with Network Disconnection Protection

1. Product Overview

The MBSL16DI16RO module is a 16-channel digital isolated input and 16-channel relay isolated output module, which is output through an isolated RS485 interface.

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

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

3) The communication circuit of the module adopts lightning protection, anti-interference design and power polarity protection.

4) RS485 communication signal output interface adopts over-voltage and over-current double protection.

5) This module reserves the output disconnection protection function. When the module slave station detects that the master station has not sent data beyond the set time, it will automatically reset the output to protect the safety of the field device. (This function is not available by default and can be set by software)

6) The communication format of this module can be set by software.
