Schneider Electric Telemecanique 9001-DOB20 Contact Block

The Schneider Electric Telemecanique 9001-DOB20 is an auxiliary contact block for 9001-series control stations, providing electrical switching for pushbuttons and selector switches in operator interfaces. Designed for operator device assembly mounting, it uses screw-terminal connections for straightforward wiring in industrial control circuits. This model is part of the 9001 Control Station Components series and supports use in industrial environments across signaling circuits in control panels, motor control centers, manufacturing equipment, conveyors, packaging machinery, process control equipment, assembly lines, and factory automation panels. Common replacements include Schneider Electric 9001KA1, Allen-Bradley 800T-XA, and Siemens 3SU1400 contact blocks, reflecting its compatibility within the 9001 family. The 9001-DOB20 functions as an auxiliary contact block to provide additional electrical switching for operator control devices within 9001 panels, supporting reliable signaling in industrial control circuits.
