Sensata Technologies D1210 Relay

Sensata Technologies’ D1210 is a Series 1 10 A solid-state relay (SSR) for AC loads, configured as SPST-NO (1 Form A) with a 3–32 VDC input and a 24–140 VAC load range. Encased in the hockey-puck style panel-mount package common to Crydom Series 1 SSRs, the device uses an optically isolated input to provide electrical isolation between control and load circuits while simplifying installation in control panels. With zero-cross switching, it minimizes electrical noise and arcing when energizing or de-energizing AC loads, making it suitable for automation tasks such as heaters, fans, small motors, and other mains-powered devices in industrial environments. The D1210 delivers a rated 10 A load current, enabling reliable control of moderate-power AC circuits in compact form factors. As part of Sensata Technologies’ Crydom lineage, the D1210 maintains the Series 1 electrical characteristics and form factor that have made these relays a common choice for panel builders and machine manufacturers seeking a solid-state interface between low-voltage control logic and higher-voltage AC loads.
