PLC Controller with Operator Panel – Compact Solution for Automation

This Unitronics controller from the M91 series combines the functionality of a PLC controller and an HMI operator panel in one device. It is an ideal solution for a wide range of industrial applications where reliability, ease of programming and cost reduction are important. The device is characterized by its compact dimensions and the possibility of mounting both on a DIN rail and directly on the panel.

Versatility and functionality

The M91-2-R1 controller offers 10 digital inputs, 6 relay outputs and 1 analog input. This configuration allows you to control various processes and devices. The built-in operator panel with an LCD display allows you to visualize process data, monitor the device status and interact with the system directly on site. This gives the operator full control over the process without the need for an external computer or interface.

Construction and operating parameters

The device operates at 24V DC, and its typical current consumption is 140 mA. It has an RS232 communication port for programming and communication with other devices. The robust construction ensures reliable operation even in harsh industrial conditions. The controller is sold with U90-Ladder software, which allows easy programming of the controller in ladder logic.

Applications and benefits

• Automation of small facilities: ideal for controlling machines, production equipment, HVAC systems and other industrial applications on a small scale.
• Cost reduction: integrating a PLC controller and an HMI panel into one device saves space and installation costs.
• Ease of programming: the intuitive U90-Ladder software makes it easy to create and modify control programs.
• Process visualization: the built-in operator panel allows you to monitor the device status and process parameters in real time.
• Flexibility: the possibility of expanding the system with additional input/output modules (available separately) allows you to adapt the controller to specific application needs.
• Reliability: the solid construction ensures long-lasting and trouble-free operation of the device.
• Mounting: The possibility of mounting on a DIN rail or directly on the panel provides great freedom in installing the device.

Additionally, it is worth mentioning the possibility of using the analog input to measure signals from temperature, pressure or liquid level sensors, which expands the range of applications of the controller. The relay outputs allow you to control loads with higher power, such as electric motors or heaters.
