SKA-20420 CELDUC Relay Weidmuller Rail Mount

Review CELDUC Ska 20420 Relay Weidmuller Rail Mount. Used

The CELDUC S Ka-20420 is a versatile rail-mounted relay from WEIDMULLER, suitable for a wide range of applications in automation and control systems requiring 5-24V DC coil voltage. This relay is part of the S series, which is known for its compact size, robust design, and easy installation.

The CELDUC S Ka-20420 is a 2-form-A, 1-coil, normally open (NO) relay, which means that it has two contacts that are normally open and are closed when the coil is energized. It can handle a maximum current of 20A at 250V AC or 30A at 24V DC, making it suitable for managing medium-sized loads. The coil resistance is 100 ohms, and the contact resistance is 0.2 ohms maximum.

This relay is housed in a sturdy, IP65-rated plastic enclosure that protects it against dust and water spray. The rail-mounting design allows for easy integration into DIN-rail-based systems, ensuring a neat and organized installation. The relay can be mounted horizontally or vertically, depending on the available space and the orientation of the DIN rail.

The CELDUC S Ka-20420 comes with a built-in diode for coil protection, which prevents the inductive energy from damaging the relay when the coil is de-energized. It also features a transparent cover over the coil, allowing for easy visual inspection of the coil status.

The relay can be operated in various modes, including normally open (NO), normally closed (NC), and changeover (CO) configurations. It also supports optional auxiliary contacts, which can be configured as NO or NC depending on the application requirements. The CELDUC S Ka-20420 is compatible with various control devices and software, making it a flexible and adaptable solution for various automation applications.

The CELDUC S Ka-20420 is a reliable and efficient relay that offers easy installation, robust design, and excellent protection against environmental factors. It is a valuable addition to any automation or control system where medium-sized loads need to be managed in a compact and organized manner.

The Weidmuller Celduc SKA-20420 Ska 20420 relay is a rail-mounted electromechanical relay suitable for various automation applications. Here are some potential pros and cons of buying this relay:

1. Rail-mounting design: This relay can be easily mounted on DIN rails, making it ideal for applications where space is a concern.

2. Versatile voltage range: The relay operates on a wide voltage range of 5-24V DC, making it suitable for various power supply systems.

3. Robust construction: The relay is designed to withstand harsh industrial environments, ensuring reliable operation.

4. Compact size: The relay has a small footprint, making it suitable for applications where space is limited.

1. Limited current capacity: The relay has a maximum current capacity of 2.5A, which may not be sufficient for high-current applications.

2. Single-pole, double-throw (SPDT) design: The relay is an SPDT type, which may not be suitable for applications requiring multiple contacts or more complex switching configurations.

In conclusion, the Weidmuller Celduc SKA-20420 Ska 20420 relay is a reliable and space-saving option for applications requiring a rail-mounted, DC-operated relay with a wide voltage range. However, it may not be suitable for applications requiring high current capacity or more complex switching configurations.

Based on the information provided, I would recommend this relay for applications where a compact, rail-mounted, and widely voltage-range compatible relay is required. However, it's essential to consider the specific requirements of the application, such as current capacity and contact configuration, before making a final decision.
