MVI69L-MBS Modbus Serial Lite Communication Module for CompactLogix

MVI69L-MBS Modbus Serial Lite Communication Module for CompactLogix

The MVI69L-MBS, Modbus Serial module for the CompactLogix™ series of controllers is designed for smaller applications where communication between a few Modbus Serial devices is required. This module has an Add-on Profile and an Add-on Instruction to reduce commissioning time. The MVI69L-MBS has a single serial port and can support either Master or Slave connectivity to interface with a variety of devices using the Modbus Protocol.

A conformal coating option is available for this product.

Features and Benefits
