Product Description
The SSR-40DA Solid State Relay Module, with a 3-32VDC/24-380VAC 40A specification, is a solid state relay capable of switching high-current AC loads via lower voltage DC signals. Solid state relays have several advantages over mechanical relays, including quicker switching times, increased longevity, and silent, spark-free operation.
Solid state relays are advantageous because they switch using significantly lower voltage and current compared to mechanical relays. Additionally, the absence of moving parts means they can operate faster and more frequently without degradation.
This particular solid state relay can manage a current load of up to 40A. It operates with a 3-32V DC input and employs a zero cross trigger control method for load switching. The relay features four screw terminals for connection to ring or fork connectors and includes a plastic cover to safeguard the terminals.
Features :
- Long service life and high reliability
- Reduced electromagnetic interference
- Highly reliable, compact size designed to offer users maximum simplicity.
