The ABB MT‑110B is a modular panel‑mounted potentiometer designed as a control operator device in industrial control panels and automation systems. It features a black knob and non‑illuminated design with a plastic bezel, intended for use where adjustable resistance control is needed—for example, adjusting speed references, intensity levels, or setpoints in control circuits. The modular design allows it to snap into compatible pilot device assemblies and integrates into standardized 22 mm cutouts found in control panels.
