The M-2347 is an adapter panel which, when combined with the M-2001 Series Digital Tapchanger Control, provides convenient direct replacement for Allis-Chalmers UJ-1 regulator controls. The M-2347 consists of a front panel, supplemental printed circuit board, 24-pin extension cable and 6-pin extension wire harness. Mounting of the front panel and supplemental printed circuit board onto the control panel frame requires hole drilling following the instructions provided with the M-2347.

• Connects easily to the M-2001 Series Digital Tapchanger Control using mounting screws and 24-pin connector
• Provides mechanical replacement of the old regulator control using the same control panel mounting frame, hardware and seven-position jack plug
• Provides built-in CT shorting protection when the M-2001 Series Digital Tapchanger Control is removed
