Review SQUARE D Square8501ho80 Relays

The Square D 8501HO80 Relay is a versatile and robust electrical component designed for various industrial automation applications. This relay is part of Square D's HO80 series, which is known for its high performance and reliability.

The 8501HO80 is a 5-form-C, 8-contact, normally open (NO) relay. It is suitable for controlling up to eight loads independently, making it an excellent choice for applications requiring multiple load control functions. Each contact can handle current up to 10A at 125VAC or 250VAC, 60Hz, and up to 1A at 24VDC.

This relay features a high-quality, silver-plated contact material that ensures excellent electrical conductivity and long-lasting contact life. The contacts are also rated for a contact life of 50 million cycles, ensuring reliable operation even in heavy-duty applications.

The 8501HO80 is constructed using a robust die-cast aluminum housing that provides excellent heat dissipation and protection against environmental factors. The relay's compact size, 4.7 x 2.2 x 1.8 inches, makes it easy to install in a variety of control panel applications.

The relay's coil is rated for a voltage of 120VAC, 60Hz, and a current of 0.5A. It also features a low coil resistance, which results in faster switching times and reduced power consumption. The relay can be operated in temperatures ranging from -40 F to 140 F (-40 C to 60 C), making it suitable for use in a wide range of environments.

The 8501HO80 comes with a built-in over-voltage protection feature that safeguards the relay against voltage surges, ensuring a longer lifespan and improved reliability. It also features a removable terminal block that simplifies wiring and makes installation easier.

This relay is RoHS compliant, meaning it contains no lead or other restricted substances. It is also UL and CSA recognized, ensuring that it meets the highest safety and quality standards.

In summary, the Square D 8501HO80 Relay is a high-performance, reliable, and versatile electrical component that is perfect for controlling multiple loads in industrial automation applications. Its robust construction, long contact life, and fast switching times make it an excellent choice for a wide range of control panel applications.

The Square 8501HO80 relays are opto-isolated relays commonly used in various automation and control applications. They offer several advantages and disadvantages, which are discussed below.

1. Opto-isolation: The primary advantage of Square 8501HO80 relays is their opto-isolated design. This feature ensures that the control circuit and the load are electrically separated, preventing potential electrical interference and ensuring safety.

2. High reliability: These relays have a long lifespan due to their solid-state design and lack of moving parts. They are also resistant to electromagnetic interference (EMI) and radio frequency interference (RFI), which makes them suitable for use in industrial environments.

3. Wide operating temperature range: The Square 8501HO80 relays can operate in a wide temperature range (-40 C to 85 C), making them suitable for use in various applications.

1. Limited current capacity: The Square 8501HO80 relays have a limited current capacity (1A maximum), which may not be sufficient for some applications.

2. Limited voltage rating: These relays have a voltage rating of 24V DC and 115V AC, which may not be suitable for high voltage applications.

3. Higher cost: Compared to other types of relays, opto-isolated relays like the Square 8501HO80 may be more expensive due to their advanced design and features.

The Square 8501HO80 relays offer several advantages, including opto-isolation, high reliability, and wide operating temperature range. However, they have some limitations, such as limited current capacity, voltage rating, and higher cost.

If your application requires opto-isolation, a wide operating temperature range, and high reliability, then the Square 8501HO80 relays may be a suitable choice. However, if your application requires higher current capacity or voltage rating, then you may need to consider alternative relay types or models. Additionally, if cost is a concern, you may want to explore cost-effective alternatives to opto-isolated relays.
