Modbus TCP/IP Lite Communication Module for CompactLogix


The MVI69L-MBTCP Modbus TCP/IP module is ideal for smaller applications that utilize the CompactLogix L2 controllers. The module has an Add-on Profile and an Add-on Instruction to reduce commissioning time.

The MVI69L-MBTCP has a single Ethernet port for diagnostic and application data. It supports both Client and Server connectivity to interface with a variety of devices using the Modbus TCP/IP Protocol.

A conformal coating option is available for this product.
