High isolation solid-state relays are also speedy

1 November 2006 Switches, Relays & Keypads

The ASSR-3220-002E and ASSR-322R-002E from Avago Technologies are dual-channel high-speed optically-isolated Mosfet-output solid-state relays (SSRs). These are 250 V, 0,2 A, 2 Form-A relays that provide re-inforced insulation of 3,75 kV a.c. without compromising speed performance, with guaranteed performance across the -40 to +85°C temperature range.

The relays are suited for application in telecommunication switching, data communications, industrial controls, medical, security, automatic test equipment, data acquisition systems, measuring instruments and EMR/reed relay replacement.

Compared to electromechanical relays, Avago says its ASSR-3220 and ASSR-322R products offer distinct advantages, including the elimination of contact bounce, and problems due to shock, vibration, or mounting position. They have no wear-out mechanism, limiting the number of operations, and require no minimum contact 'wetting' current. They are also free from magnetic fields, do not generate electrical noise, and are not sensitive to electromagnetic interference.
