Eaton’s D93 series of solidstate relays is a line of heavyduty industrial relays in the common “hockey puck” package. The removable, finger-safe cover and optional accessories make the D93 safe and easy to install in a variety of applications. Models are available in a variety of input voltages and switch types up to 75A.

Application Description

A solid-state relay (SSR) can perform many applications that an electromechanical relay can perform. The SSR differs in that it has no moving mechanical parts within it and has some distinct advantages over an electromechanical relay. When used correctly in the intended application, the SSR provides a high degree of reliability, a long service life, significantly reduced electromagnetic interference, fast response and high vibration resistance. Applications for the SSR typically include equipment that requires high cycling rates, low acoustical or electrical noise, or high vibration resistance. Some examples are medical equipment, heating/cooling equipment, lighting control and pumps/compressors, among others.
