Akytec PR205: Compact Programmable Relay with Ethernet, RS485, and LCD Display

August 19, 2025

In today's industrial environment, efficiency, speed, and reliability are critical prerequisites for automation components. Each new generation of programmable relays must bring something new to expand yourautomation core application boundaries.

The Akytec PR205 programmable relay follows this path—with innovations across various dimensions.

Compact

The PR205 controller is designed with space efficiency in mind, without compromising power or functionality. It is an ideal solution for both small-scale equipment and large systems requiring precise and stable control. The DIN rail mounting allows easy installation in industrial cabinets with high IP protection or in locations easily accessible to staff.

User-friendly

The built-in graphical LCD display provides intuitive visualization and user interface. Easily monitor system data, make adjustments, and enhance the user experience.

The 2.4'' IPS graphical display (320x240 px) can display process elements, statuses, temperature curves, and recipes in vibrant 65,535 colors. The display is complemented by six mechanical buttons that can be freely configured for intuitive navigation and data input/output.

Functional

The PR205's high functionality is based on its extensive I/O range and the akYtec ALP programming environment, which offers ready-made popular function blocks for your process control.

PR205 I/O configuration:

4 analog inputs: Pt1000, NTC/PTC, resistive, 4–20 mA / 0–10 V
3 analog outputs: 4–20 mA / 0–10 V
6 digital inputs, including 2 high-speed inputs (up to 100 kHz) for pulse counting
8 digital outputs—relay and transistor

Easily integrable

With Ethernet support, the PR205 offers fast and secure data exchange, as well as seamless integration with existing networks and systems. Use remote access for diagnostics, monitoring, and configuration—anytime, anywhere.

PR205 communication connectivity:

Ethernet—configurable as Modbus TCP Master or Slave, enabling the PR205 to integrate with SCADA, HMI panels, or control other TCP Slave devices
2× RS485—Modbus RTU/ASCII, configurable as Master or Slave, providing additional integration with I/O modules, frequency converters, and other devices

Why choose the PR205?

Complete process transparency with a visually intuitive graphical display
Easy integration and remote management via Ethernet and RS-485
High I/O diversity—analog, digital, expandable
Compact and durable design suitable for both manufacturing and R&D
Virtual monitoring and efficient algorithm development tools in the akYtec ALP environment

Discover the convenience of future control today—with the PR205, you get transparency, control, and flexibility in one device!
