Solutions for industrial automation with Circutor input/output modules

Circutor | 29 de May de 2025

In an increasingly digitalized and demanding industrial environment, having tools that simplify automation and facility monitoring is key to improving operational efficiency, reducing errors, and optimizing energy consumption. In this context, digital and analogue input/output modules have become essential devices for smart technical management, especially when advanced SCADA or PLCs are not available.

What are LM modules and what are they used for?

Circutor's LM-A42-D11 and LM-D44 models are designed to manage digital and analogue signals in industrial, service or tertiary facilities. They are used to:

- › Automate simple processes without the need for a PLC
- › Collect sensor and equipment data.
- › Monitor physical variables (such as temperature, pressure or load status).
- › Execute local control logic through configurable inputs and outputs.

LM. These devices allow you to manage analogue and/or digital inputs and outputs, collect field data and act directly on loads or signals without relying on a central control system.

Automation and control without the need for a PLC

One of the key advantages of LM modules is their ability to operate autonomously, without relying on a centralized system. This enables:

› Event and status monitoring.
› Activation of outputs (such as relays) in response to predefined conditions.
› Setting up local alarms without complex programming.

Thanks to these capabilities, LM modules make it possible to automate repetitive tasks, shorten response times and streamline preventive maintenance.

Inputs, outputs and conversion of digital and analogue signals

Circutor’s LM models allow automatic conversion of analogue signal units. For example, an input in volts or milliamps is directly converted into degrees Celsius, percentage, or bars, as appropriate. This means:

› Direct and error-free interpretation.
› No more manual conversion steps.
› Ease of use for field technicians.

These features are especially valuable in installations where personnel need quick and reliable readings of sensor status.

Modbus connectivity: RS-485 and TCP/IP Wi-Fi

LM modules are compatible with Modbus RTU (RS-485) and Modbus TCP/IP (Wi-Fi) protocols. This dual connectivity allows for:

› Use in both new and existing installations.
› Choice between wired or wireless communication.
› Easy integration with SCADA, BMS and other systems.

In addition, the LM-A42-D11 and LM-D44 are compatible with the register map of previous models (such as the LM4A-2IO-M and LM4I-4O-M), making it easier to migrate without reprogramming software or modifying existing configurations. This technical continuity shortens adaptation times and protects previous infrastructure investments.

Energy integration: "hour meter", CAE and ISO 50001

The integrated "hour meter" function allows the uptime of a device to be recorded via digital inputs. This is useful for:

› Knowing how long an equipment has been operational
› Obtaining data for energy audits
› Justifying measures in Energy Saving Certificate (CAE).
› LMs provide valuable data for ISO 50001.

Typical applications include industrial lighting, air conditioning or monitoring of production processes.

Programming-free configuration: MyConfig and Web Server

A major advantage of these modules is their intuitive setup:

› MyConfig app for quick adjustments.
› Integrated web server, accessible via Wi-Fi, for detailed configurations.

These options allow technicians without advanced knowledge to:

› Configure Inputs/outputs.
› Create internal logic.
› Program local alarms.

All of this without the need for additional software or coding.

Compatibility with existing PowerStudio and SCADA systems

LM is designed to work with the embedded and on-premise versions of PowerStudio SCADA WAVE This enables:

› Centralized monitoring of installations.
› Integration into SCADA architectures without redesigning systems.
› Reduced start-up times.

This is key in projects with existing infrastructure, where changes must be minimal and scalable.
