DC To AC SSR-25DA Solid State Relay Module 3-32 VDC /24-380VAC

Description

This is DC To AC SSR-25DA Solid State Relay Module 3-32VDC/24-380VAC 25A. A solid-state relay (SSR) allows you to control high-current AC loads from lower voltage DC control circuitry. Solid-state relays have several advantages over mechanical relays.

One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out.

This particular SSR can switch current loads of up to 25A with a 3-32V DC 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.

DC To AC SSR-100DA Solid State Relay Module 3-32VDC/24-380VAC 100A

This is DC To AC SSR-100DA Solid State Relay Module 3-32VDC/24-380VAC 100A. 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 100A with a 3-32V DC 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.
