Bell & Howell CS-538-000D REV 2 Circuit Board

Bell & Howell CS-538-000D REV 2 Circuit Board is a Bell & Howell printed circuit board identified by the part number CS-538-000D and revision 2. It is also cataloged under the alternate designation 0642000D LC, a cross-reference that appears in product descriptions and listings. This board represents a discrete circuit-board assembly from the Bell & Howell CS-538 hardware family and carries the REV 2 designation, indicating this is the second engineering revision of this model. The CS-538 naming convention appears across multiple variants, including CS-538-000B in contemporary listings, which shows REV 2 as a common revision for this lineage. In secondary-market and surplus catalogs, CS-538 boards are frequently encountered as replacement parts for legacy Bell & Howell devices that used the CS-538 architecture. The presence of both the CS-538-000D designation and the cross-reference 0642000D LC underscores this component's role as a device-specific circuit-board module within the Bell & Howell ecosystem.
