The IDEC RY4S-UL Relay SY45-05C is a versatile and reliable electrical component, designed for use in various applications where reliable control of electrical circuits is essential. This 24V DC relay is a part of IDEC's UL-listed series, ensuring compliance with stringent safety standards in the United States.
The IDEC RY4S-UL Relay SY45-05C is a 4-pole, 5-contact, normally open (NO) relay, which means it allows current to flow through the contacts when it is not energized and breaks the current when it is energized. The relay operates on a 24V DC power supply, making it suitable for use with a wide range of low-voltage systems.
The relay's contacts are rated for a maximum operating current of 5 A, ensuring that it can handle the electrical loads it is controlling efficiently. The contacts are also designed to provide a low contact resistance, ensuring fast and reliable switching actions. The SY45-05C also features a high contact rating of 10,000 cycles at 5 A, making it suitable for use in applications with high switch cycle requirements.
The IDEC RY4S-UL Relay SY45-05C is designed with a compact size, measuring 21.9 mm x 28.1 mm x 13.8 mm, making it easy to install in tight spaces. The relay is also equipped with a plastic base, which is compatible with the SY45 series, providing flexibility in selection of relay types based on specific application requirements.
The relay's coil is rated for a maximum voltage of 30V and a maximum current of 0.15 A, ensuring that it can be easily energized without the risk of damage to the relay or the power supply. The relay's coil is also equipped with a built-in thermal protection mechanism, which prevents the coil from overheating in case of continuous operation or overcurrent conditions.
In summary, the IDEC RY4S-UL Relay SY45-05C is a reliable and versatile 24V DC relay, suitable for use in a wide range of applications. Its UL-listed status ensures compliance with safety standards, while its compact size, high contact rating, and built-in thermal protection make it an ideal choice for applications with high switch cycle requirements and tight space constraints.
