The EKF electrical equipment brand has expanded its range with the introduction of PRO-Relay programmable relays. These devices are designed for local and small automation systems and occupy an intermediate position between traditional relay automation and programmable logic controllers (PLCs). PRO-Relay allows you to replace relays, timers and counters, simplifying equipment setup and reducing the amount of cable connections.

Main advantages of PRO-Relay

PRO-Relay is designed to control automatic transfer switch (ATS) and various actuators, including:

• Pumps, barriers, ventilation and heating systems;
• Lighting systems and small automated units;
• Actuators with speed, direction, start and stop adjustment functions.

In addition, the device can be used in quality control of manufactured products, equipment testing and other tasks requiring logical management.

Flexibility and ease of programming

One of the key features of PRO-Relay is easy setup without complex programming. The device supports logical control, allowing you to change parameters depending on the production process.

For ease of setup and integration, PRO-Relay is equipped with modern interfaces:

• RS-485 and Ethernet;
• Support for protocols Modbus ASCII, Modbus RTU (Master-Slave) and Modbus TCP (Client-Server).

Relay programming is carried out in the functional block diagram (FBD) language, which makes the process intuitive even for specialists without in-depth knowledge of programming.

Functionality and technical characteristics

• Built-in LCD display allows you to monitor the system and make changes to operating algorithms in real time.
• Integrated keyboard allows you to control output signals and set internal variable parameters.
• Flexibility in installation: mounting on DIN-rail 35 mm, mounting plate or flat surface with screws.

Wide operating temperature range from -20 to +55 °C, which makes PRO-Relay a universal solution for various operating conditions
