Relpol NEED-230AC-22-08-4R-D Programmable Relay, 230V AC, 8 Inputs, 4 Relay Outputs, with Display and Keypad

The Relpol NEED-230AC-22-08-4R-D is a compact and versatile programmable logic relay engineered for efficient control in industrial and building automation environments. Operating on a 230V AC power supply, this controller provides a robust solution for managing small-scale automation tasks, timing sequences, and complex logic operations. The device features an integrated LCD display and a user-friendly keypad, allowing for direct configuration, parameter adjustment, and real-time monitoring of control processes without the need for external programming tools.

Advantages

This programmable relay offers significant flexibility for system integrators and maintenance professionals by combining logic control and user interface in a single, space-saving unit. Its ability to operate directly on standard 230V AC mains voltage simplifies installation by eliminating the need for additional power supply modules. The inclusion of a built-in display and keypad ensures that operators can quickly modify settings or diagnose system status on-site, enhancing operational efficiency and reducing downtime during maintenance or process adjustments.

Suitable for

• Small-scale industrial automation systems
• Building automation and lighting control
• HVAC system management
• Timing and sequence control in electrical panels
• Automated gate and barrier control

This device may not be suitable for high-speed motion control applications or complex processes requiring extensive analog signal processing. It is also not intended for use in environments with extreme electromagnetic interference or hazardous conditions that require specialized explosion-proof equipment.

Key specifications

• Supply voltage: 230V AC
• Digital inputs: 8
• Relay outputs: 4
• Integrated LCD display and keypad
• Compact modular design

To use the Relpol programmable relay, mount the unit onto a standard DIN rail within an electrical enclosure. Connect the power supply to the designated terminals and wire your sensors to the 8 digital inputs and your actuators to the 4 relay outputs. Once powered, use the integrated keypad and LCD screen to navigate the menu, configure the logic parameters, and set up the desired control functions according to your specific application requirements.

What to consider before purchase

• Ensure the 230V AC supply matches your local electrical infrastructure
• Verify that the number of inputs and outputs meets your project requirements
• Confirm that the logic capabilities of the relay align with your automation task
• Check the physical dimensions to ensure compatibility with your existing control cabinet

For optimal performance and longevity, ensure the relay is installed in a well-ventilated enclosure protected from moisture, dust, and extreme temperatures. Regularly inspect terminal connections to prevent loose wiring and ensure consistent signal transmission.
