Foxboro MTRJ-DL-02-20M Remote I/O Module

Product Description

The Foxboro MTRJ-DL-02-20M is a configurable remote I/O module developed for integration with Foxboro I/A Series DCS and PLC-based control systems. It provides a flexible interface for field devices by supporting both analog and discrete signals within a single unit, reducing hardware complexity in distributed architectures.

Each of the 20 channels on the MTRJ-DL-02-20M can be configured individually, allowing deployment in mixed-signal environments where different types of field inputs and outputs must coexist. The module supports industrial communication standards including Modbus/TCP, Modbus/RTU, and Ethernet/IP, enabling interoperability with a wide range of control systems.

Its enclosure is designed for industrial conditions, offering IP65 protection against dust and water ingress. The unit can be installed on DIN rail systems or mounted directly on panels or walls, providing flexibility for field-level installation.

Some vendor listings also associate this model number with a fiber-optic communication variant using MTRJ connectors and a 20-meter duplex multimode cable. This variant is typically used for noise-immune, long-distance data transmission in electrically harsh environments.
