Description
This is AC To AC SSR-75AA Solid State Relay Module 80-250VAC/24-380VAC 75A. A solid-state relay (SSR) is an electronic switch, which, unlike an electromechanical relay, contains no moving parts. The types of SSR are photo-coupled SSR, transformer-coupled SSR, and hybrid SSR. A photo-coupled SSR is controlled by a low voltage signal which is isolated optically from the load.
The control signal in a photo-coupled SSR typically energizes an LED which activates a photo-sensitive diode. The diode turns on a back-to-back thyristor, silicon-controlled rectifier, or MOSFET transistor to switch the load.
This particular SSR can switch current loads of up to 75A with an 80-250VAC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.
Features:
- Long service life and high reliability
- Reduced electromagnetic interference
- Highly reliable, compact size designed to offer users maximum simplicity.
