Ethernet Remote IO Modules

Ethernet Remote I/O Modules provide a flexible way to connect field devices to control systems over industrial networks.

They allow I/O to be installed closer to sensors and equipment, reducing wiring and improving signal reliability.

These modules are commonly used in distributed control systems where scalability and remote monitoring are required.

Metromatics provide local sales, service and support for the product range.

 

Ethernet Remote IO Solutions for Modbus TCP/IP, Ethernet/IP, and Profinet Networks

Metromatics offers Ethernet Remote I/O solutions for Modbus TCP/IP, EtherNet/IP, and PROFINET networks. We provide these through our partner, Acromag.

These modules support remote I/O, distributed process control, and factory automation applications.
They provide a reliable interface between field devices and control systems over industrial Ethernet.

Analog and digital Ethernet I/O modules connect sensors and actuators to PLC and SCADA systems.  Achieved by using Modbus TCP/IP and EtherNet/IP (CIP) protocols.

EtherNet/IP combines standard Ethernet with the Control and Information Protocol (CIP).  Therefore, making it well suited to industrial automation environments requiring real-time data exchange.

Modules are available with CE compliance and approvals.  Such as UL/cUL Class 1 Div 2 and ATEX certification for hazardous areas.

Types of Ethernet Remote I/O Modules

Ethernet Remote I/O Modules are available in different configurations depending on the signal type and application.

Ethernet Analog IO Modules NT2240Digital Ethernet IOEthernet Analog & Discrete IO Modules 951EN 952EN
Analogue Ethernet IO
Digital Ethernet IO
Multi-Function Ethernet IO
Analog I/O modules are used for continuous signals.  Such as 4–20 mA, 0–10 V, temperature, and other process measurements.
They are typically used for monitoring pressure, flow, level, and temperature.
Digital I/O modules handle on/off signals.
They are used for switch status, alarms, and control of devices such as relays and motors.

These modules provide an isolated Ethernet interface for both analog and digital I/O signals.

Multi-range analog inputs and outputs support a wide range of industrial sensors and control devices.

How Ethernet Remote I/O Modules Work

Ethernet Remote I/O Modules are installed close to field devices and connected directly to sensors and actuators.

The module converts signals into digital data and transmits it over Ethernet to a PLC or SCADA system.

This allows real-time monitoring and control without long cable runs back to a central control panel.

Key Features

Ethernet Remote I/O Modules are designed for industrial environments and offer:

  • Support for Modbus TCP and EtherNet/IP

  • Flexible analog and digital I/O configurations

  • DIN rail mounting for easy installation

  • Wide operating temperature ranges

  • Built-in diagnostics for monitoring system health


Benefits of Ethernet Remote I/O Modules

Using Ethernet-based I/O improves both installation and long-term system performance.

Reduced wiring lowers installation costs and minimises potential failure points.
Distributed architecture improves scalability and makes future expansion easier.
Placing I/O closer to field devices also improves signal quality and system reliability.
