Product Description:

The HN308 is a timer and small controller manufactured by Danaher as part of the Timers and Controllers series. In automated machinery, it generates preset timing or count outputs that coordinate pumps, heaters, or conveyor stages without using PLC scan time. The device occupies a single panel position and connects through standard screw terminals for straightforward control cabinet wiring.

For enclosure installation, the unit is supplied for surface mounting, and Danaher includes mounting hardware so separate fasteners are not needed. Its housing carries a NEMA 1 rating, which suits clean indoor control cabinets and helps protect the electronics from accidental contact. Cabinet depth is limited to 1.625 in (41.27 mm), so the controller can fit behind shallow panel doors. All field wiring terminates on a terminal block, which simplifies removal during maintenance.

The front bezel measures 5.750 in (146.05 mm) tall by 4.125 in (107.95 mm) wide, giving operators a clear viewing area while matching common instrument layouts. A circular panel opening of 3.187 in (80.95 mm) is required, and the round cutout helps center the device in the panel. That geometry supports even gasket compression across the cabinet face for a consistent seal.
