PLC controller with 3.5" color touch panel HMI: 20DI, 2DI/AN, 16TO V350-J-T38

PLC Controller with HMI Panel – a Compact Solution for Automation

This PLC controller from Unitronics combines the functionality of a programmable logic controller with an intuitive operator panel equipped with a 3.5-inch color touchscreen. It is an ideal solution for a wide range of industrial applications where both efficient process control and easy operation and data visualization are important. The device offers 20 digital inputs, 2 digital-analog inputs, and 16 transistor outputs, providing flexibility in configuration and adaptation to specific application needs.

Functionality and Capabilities

This controller stands out for its versatility and rich set of features. The integrated HMI panel enables direct interaction with the process, presenting data in a readable way and allowing for quick modification of operating parameters. Additionally, the device offers:

• Versatile Inputs: Support for digital, analog (0-10Vdc, 0/4-20mA) signals, and temperature sensors (PT100 and thermocouples).

• Communication: RS232/485 ports for serial communication and optionally Ethernet for integration with industrial networks. Support for Modbus master/slave and CANbus (option) protocols.

• Program Memory: 1MB of program memory, allowing for the implementation of complex control algorithms.

• Fast Counters: Built-in fast counters (up to 10 kHz) ideal for applications requiring precise pulse measurement.

• PID Controllers: Built-in PID controllers with auto-tuning function make it easy to precisely control temperature and other process parameters.

• Expandability: Possibility of expansion with additional I/O modules (up to 512 points) via the expansion port.

• Real-Time Clock: Enables event logging and real-time task scheduling.

• Memory Backup: Battery ensures memory retention for at least 7 years.

Applications in Industry

This controller finds application in many areas of industry, including:

• Control of technological processes and assembly lines.

• Building automation – control of lighting, heating, ventilation and air conditioning.

• Packaging and production machines.

• Pump and compressor stations.

• Conveyor belts and material transport systems.

• Furnaces, dryers and other heating devices.

• Process data monitoring and visualization systems.

Thanks to its compact design and ease of installation (panel or DIN rail), this controller will work well both in new installations and in the modernization of existing automation systems. Its intuitive ladder programming interface makes it easy to create and modify control programs, and the integrated HMI panel provides convenient operation and data visualization for operators.
