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.
![]() | ![]() | ![]() |
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
