The Sensata | Crydom DPI Series is a line of hockey puck-shaped, dual-channel AC output solid state relays intended for dependable performance and ease of installation.
These SSRs, which include push-in wire connections, make setup easier while also providing better mechanical and thermal design than similar items on the market. Each dual-output device is rated for 20 amps at 24 to 280 VAC.
