Accuenergy Answers Rising Industrial I/O Demand with the AcuIOM I/O Module

Toronto, ON – Jul 07, 2026 – Accuenergy is pleased to announce the official launch of the AcuIOM Universal I/O Module, a flexible and scalable input/output solution designed for industrial monitoring, control and automation applications. The I/O module allows users to better manage and connect to a variety of signal types through a single platform. Available in four models with a range of I/O configurations, including analog, digital, and relay options on select versions, the AcuIOM can integrate with PLC, SCADA, building management system, and other automated platforms.

As Industry 4.0 drives the shift toward connected, distributed automation, organizations are seeking to better integrate a diverse range of field devices, sensors, and control systems across a single architecture. Flexible I/O modules are part of the critical technology leading this transition, enabling engineers to bridge equipment to modern infrastructure without major system overhauls. The AcuIOM supports both Modbus RTU and Modbus TCP, when combined with different configurable analog, digital, and relay I/O options, it is positioned to be an important connecting block to expand data acquisition and control capabilities at the edge.

"Industrial systems are becoming increasingly connected, yet many facilities still face challenges integrating field devices and control systems across multiple platforms," said Ryan Manbahal, Product Manager at Accuenergy. "The AcuIOM was developed to provide a flexible and scalable I/O platform that simplifies signal acquisition, monitoring, and control while reducing deployment complexity for system integrators and facility operators."

In modern industrial and commercial environments, the AcuIOM is ideal for extending the functionalities of energy and power meters by integrating external sensors and control signals, collecting pulse outputs from electrical, water, and gas meters, and enabling automated load shedding based on real-time conditions. Building automation will have noticeable gain through cost and operational efficiencies, where the AcuIOM can interface with HVAC, lighting, and control equipment to monitor statuses and adjust setpoints across an entire facility.

For industrial and process control applications, universal I/O modules directly controls pumps, fans, valves, and other field equipment through its digital and relay outputs, integrating with PLC and SCADA systems via Modbus, the open communication backbone of Industry 4.0 deployments. This same interoperability extends to data centers and critical facilities, where distributed I/O architectures and continuous environmental monitoring are essential to maintaining uptime. Any organization managing system upgrades, the AcuIOM operates as an independent, standalone remote I/O module, adding monitoring and control capability to existing infrastructure without replacing primary controllers.

Each of the AcuIOM’s four models are optimized for a distinct I/O profile. The AcuIOM-1 and AcuIOM-2 are analog-focused, offering 8 and 16 analog inputs respectively alongside analog outputs, making it well-suited for continuous sensor monitoring of parameters like temperature, pressure, and flow. The AcuIOM-3 and AcuIOM-4 offer digital and relay control, with up to 28 digital inputs, 4 digital outputs, and 2 relay outputs on the AcuIOM-4, supporting high-density status monitoring, pulse collection, and direct switching of external devices.

Both analog and digital models support 0-20mA and 0-10V signal ranges, with analog input accuracy rated at 0.2% and analog output at 0.5%. Digital inputs accept voltages up to 160Vac/dc with 2500Vac isolation, while relay outputs are rated for up to 250Vac and 5A resistive loads allowing the AcuIOM can handle real-world field conditions without additional signal conditioning.

Every AcuIOM model is equipped with both an RS485 port for Modbus RTU and a 10/100 Mbps Ethernet port for Modbus TCP, enabling the module to connect to virtually any SCADA, PLC, or building management system. A USB port is also included for local configuration and power supply to the onboard microcontroller. The module operates on 12–36Vdc with a maximum burden of 6W.

With the launch of the AcuIOM, Accuenergy continues to expand its portfolio of industrial measurement and control solutions, giving system integrators and facility operators a practical, scalable tool for meeting the demands of connected operations.
