Allen-Bradley 80165-158-53G SCR Gate Driver is a replacement SCR gate driver circuit board used in Allen-Bradley automation equipment to supply gate-drive signals to silicon-controlled rectifiers in power-control circuits. The Series H variant is listed in some catalogs, and the part is often sold as 80165-158-53G or 80165-158-53-R by suppliers. This PCB functions as the interface between control logic and SCRs, enabling controlled triggering within legacy drive systems; it is typically used as a replacement part when an existing SCR gate-driver board is needed in compatible Allen-Bradley equipment.
