The Relpol NEED-24DC-22-16-8R-D is a robust programmable relay engineered for precise control in industrial automation environments. Operating on a 24V DC power supply, this device serves as a reliable logic controller for managing electrical systems, timing sequences, and automated processes. It features a user-friendly interface with an integrated LCD display and a built-in keypad, enabling direct configuration and real-time monitoring of system status without the need for external programming tools.

Advantages

This programmable relay offers significant flexibility for small-to-medium scale automation projects by combining logic control, timing, and counting functions into a single compact unit. The inclusion of a display and keypad simplifies on-site adjustments and troubleshooting, reducing downtime during maintenance. Its relay outputs provide high compatibility with various external devices, while the 16 digital inputs allow for extensive sensor integration, making it a versatile solution for complex control logic requirements.

Suitable for

• Small-scale industrial automation systems
• Building management and lighting control
• Timing and sequence control for machinery
• Monitoring and managing sensor-based electrical installations

When it may not be suitable

This device is not intended for high-speed motion control applications or complex processes requiring advanced communication protocols like Ethernet or fieldbus integration. It may also be insufficient for systems demanding a high number of analog inputs or outputs beyond its standard digital configuration.

Key specifications

• Supply voltage: 24V DC
• Digital inputs: 16
• Relay outputs: 8
• Interface: Integrated LCD display and keypad
• Mounting: Standard DIN rail mountable

How to use

The relay is mounted on a standard DIN rail within an electrical cabinet. Once powered with 24V DC, users can navigate the menu using the integrated keypad to define logic functions, timers, and counters directly on the display. Inputs should be wired to the designated terminals, and output devices should be connected to the relay contacts according to the wiring diagram provided in the technical documentation.

What to consider before purchase

• Verify that the 24V DC power supply matches your system requirements
• Ensure the number of digital inputs and relay outputs meets your project needs
• Check if the physical dimensions fit within your existing control panel

Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring operations. Regularly inspect the terminal connections to maintain optimal electrical contact and prevent overheating in the control cabinet.
