The FC-1-388W is a normally open (NO) type relay, meaning it does not conduct current when de-energized. It features a form C contact configuration, which is commonly used for switching AC or DC loads. This configuration allows for the use of a common terminal, normally open terminal, and two normally closed terminals.

This relay comes with a coil resistance of 388 ohms and a coil inductance of 1.1 mH. Its operating temperature range is from -40 C to 65 C (-40 F to 149 F), making it suitable for use in a wide range of environments.

The FC-1-388W is designed with a rugged and durable construction. It is built with a gold-plated contact material, which ensures long-lasting and reliable contact performance. The relay also features a vibration-resistant design, with a maximum operating vibration of 10 Grms (10g), making it suitable for use in industrial environments with some level of vibration.

The FC-1-388W is a compact relay, with a dimension of 2.5 inches (63.5mm) in length, 1.7 inches (43mm) in width, and 1.0 inch (25.4mm) in height. It also comes with a mounting pattern of 2.5 inches (63.5mm) by 3.0 inches (76.2mm), allowing for easy mounting in various applications.

This relay is an excellent choice for applications requiring the switching of moderate current loads, such as industrial equipment, HVAC systems, and lighting control systems. Its heavy-duty construction, reliable contact performance, and wide operating temperature range make it a reliable and robust solution for your industrial automation needs.

The Struthers-Dunn FC-1-388W 28VDC 725 relay 00105 is a commonly used industrial-grade relay with specifications that make it suitable for various applications. In this analysis, we will discuss the pros and cons of purchasing this relay to help you make an informed decision.
