70R2S-2500 SIGMA Relay Vac

Review SIGMA Relay Dpdt 28vdc/2a Or 125 Vac

The Sigma 70R2S-2500 relay is a versatile and robust electrical component designed for various applications. This model is a 2-form-A, single-pole, double-throw (SPDT) relay, capable of handling 28 volts DC with a maximum current of 2 amperes. The relay operates within a voltage range of 125 volts AC, making it suitable for use in medium voltage systems.

This Sigma relay features a contact rating of 5945-00-177-3138, which signifies a contact capacity of 5000 cycles at 100% duty cycle. The electrical contact material is silver alloy, ensuring excellent conductivity and long-lasting performance. The relay has a coil resistance of 250 ohms and an inductance of 145 millhenries, providing a reasonable switching time and minimizing electromagnetic interference.

The relay's housing is made of a robust and durable material, designed to withstand harsh environments. It measures 32.5mm x 22.5mm x 13mm (L x W x H), making it suitable for space-constrained applications. The relay's operating temperature range is between -25 C to 70 C, ensuring reliable performance in a wide range of temperatures.

The Sigma 70R2S-2500 relay comes with built-in diodes for coil protection, which helps prevent damage caused by inductive loads. The relay also features a normally-open (NO) contact configuration, meaning the contacts are open when the relay is de-energized. When the relay is energized, the contacts close, making a connection between the two terminals.

This Sigma relay is an excellent choice for various applications where a robust and reliable SPDT relay is required, such as automation systems, industrial control systems, and telecommunications equipment. Its wide voltage range, high current handling capacity, and long-lasting contacts make it a reliable and efficient option for various applications.

The Sigma 70R2S-2500 relay is a 28VDC/2A, 125VAC, normally open, form C, single pole, double throw (SPDT) relay. Here are some potential pros and cons of buying this relay:

1. Suitable for use in industrial automation, HVAC systems, and other applications requiring heavy-duty relay action.

2. Normally open contacts can be used to switch circuits without a constant power connection.

3. Form C relay can be used in various types of circuits, making it a versatile choice for different applications.

4. Capable of handling 125VAC, making it suitable for use with high voltage circuits.

5. Relatively high current capacity of 2A, allowing it to handle more power than some other relays.

1. This relay has a larger size and weight compared to miniature relays, making it less suitable for compact applications.

2. The price point is higher when compared to some other relays with similar specifications, which may be a consideration for budget-conscious buyers.

3. The coil voltage of 28VDC may require a separate power supply or an additional component to be added to the circuit, which could increase the overall complexity of the system.

The Sigma 70R2S-2500 relay is a heavy-duty, versatile component suitable for various industrial and automation applications. Its high voltage and current handling capabilities make it a reliable choice for switching high power circuits. However, its larger size and higher price point may be a drawback for some buyers. Ultimately, the decision to purchase this relay depends on the specific requirements of the application and the budget available.

If you require a heavy-duty relay for industrial or automation applications, the Sigma 70R2S-2500 relay is a good option to consider due to its high voltage and current handling capabilities. However, if your application requires a smaller size or a lower price point, you may want to explore other options available in the market.
