The ABB CA5-04E is a versatile, multifunction digital timer relay from the established CA5 series, distinguished by its 4-module width and an analog potentiometer for time setting. The suffix "-04E" specifically indicates the 4-module housing with a front-accessible screwdriver-adjustable potentiometer ("E" type setting) and a non-display version, relying on LED indicators for status. It is designed to provide reliable and flexible timing control in a user-friendly, hardware-oriented package.
