SKHX-10A ALLIED CONTROLS Control Relay

Review ALLIED CONTROLS Vintage Control Relay

The Allied Electronics CONTROL RELAY, model SKHX-10A, is a versatile and reliable solution for automating electrical systems. This 1-Form-C, 10-Amp, 250-Vac/240-Vdc relay comes in a standard industrial size of 1.6 x 2.6 x 1.3 inches (41.1 x 66.0 x 33.0 mm), making it a great fit for various applications.

The SKHX-10A is designed with a robust die-cast aluminum housing that ensures durability and protection against harsh environments. Its operating temperature range is from -40 C to 70 C (-40 F to 158 F), making it suitable for use in a wide range of industrial conditions.

This control relay features a normally open (NO) form C contact configuration. The form C contact is a normally open, changeover contact that closes when the coil is energized, making it perfect for applications where the contact must change from one state to another when the relay is activated. The contact rating for this relay is 10 amps at 250 volts AC or 240 volts DC.

The SKHX-10A comes with a built-in overload protection feature that helps prevent damage to the coil and contact from overcurrent. This relay also has a built-in coil heater that helps maintain the coil temperature in low ambient temperature applications, ensuring reliable operation.

The contact bounce time for the SKHX-10A is typically less than 5 milliseconds, ensuring smooth and accurate contact closure and separation. The coil resistance is 100 ohms at 25 C (77 F) and the coil inductance is 1.2 mH.

The terminal configuration on the SKHX-10A includes one coil terminal, one common terminal, and ten normally open contact terminals. The relay is mounted using four #6-32 screws, which are included with the product.

The Allied Electronics SKHX-10A control relay is RoHS compliant and meets the requirements of UL and CSA standards, ensuring that it is both environmentally friendly and safe for use in industrial applications. With its robust design, versatile contact configuration, and reliable operation, the SKHX-10A is an excellent choice for automating a wide range of electrical systems.

The Allied Electronics SKHX-10A control relay is a commonly used electromechanical switching device. Here are some pros and cons that may help you make an informed decision about purchasing this relay:

1. Versatility: The SKHX-10A relay can handle a wide range of operating voltages (50 VAC to 300 VAC) and currents (up to 10A).

2. Compact Size: Measuring only 1.6 inches long, 1.0 inch wide, and 0.6 inches tall, this relay is a good choice for applications with limited space.

3. Durable: The SKHX-10A relay is designed to withstand harsh environments and can operate in temperatures ranging from -20 C to 70 C.

4. Cost-effective: Compared to solid-state relays, electromechanical relays like the SKHX-10A are generally less expensive.

1. Mechanical Contact: The SKHX-10A relay uses mechanical contacts, which may require periodic maintenance to ensure reliable operation.

2. Response Time: The mechanical switching action of the relay results in a slower response time compared to solid-state relays.

3. Power Consumption: The SKHX-10A relay consumes power even when it is not switching, which can add to the overall power consumption of the system.

The Allied Electronics SKHX-10A control relay is a reliable and cost-effective switching solution for a wide range of applications. Its versatility, compact size, and durability make it a popular choice in many industries. However, it is important to consider the potential drawbacks, such as the need for periodic maintenance and slower response time, when determining whether this relay is the right choice for your specific application.

If your application requires a reliable and cost-effective switching solution with a wide operating voltage and current range, and you are willing to accept the potential drawbacks of a mechanical relay, then the Allied Electronics SKHX-10A control relay is a good option to consider. However, if you require faster response times, lower power consumption, or a solid-state switching solution, you may want to explore other options.
