ADB 44D2415 Sign Regulator Printed Circuit Board

Allen‑Bradley 44D2415 Sign Regulator Printed Circuit Board (Part Number 44D2415‑0000), built under the ALNACO/ADB designation, is a transformer‑based sign regulator PCB assembly designed to power and regulate multiple lamp types in industrial signage. The board provides a 6.6 A regulator and accommodates common sign‑lamp sockets and lamps, including Bryant 3743 incandescent sockets and Sylvania TP29A quartz lamps, as well as 6.6 A, 30 W incandescent lamps (Phillips 24300‑6) and 6.6 A, 30 W quartz lamps (Osram 55041), plus 6.6 A, 45 W incandescent lamps (Phillips 243196) and 6.6 A, 45 W quartz lamps (Osram 55048). Regulation is offered in 3‑step and 5‑step configurations, both at 6.6 A, with defined lamp‑load options such as 3‑step: up to four 45 W lamps or eight 30 W lamps (and a variant listed as up to eight 45 W lamps); 5‑step: up to four 45 W lamps or eight 30 W lamps (and a variant listed as up to eight 45 W lamps). The assembly includes mounting and wiring hardware typical for control panels, such as a base plate, floor flange, ground lug, wire grommet, and snap bushing, with accompanying part numbers for the hardware kit referenced in the documentation. This PCB serves as a dedicated sign‑regulator module compatible with legacy Allen‑Bradley/ALNACO sign control installations, delivering regulated power to industrial sign lamps within a compact, replaceable circuit board format.
