DESCRIPTION

As a completely self-contained timer/counter/display module, the SUB-

CUB-T can be treated as a component, just like any other I.C. The module

contains a low power integrated circuit (that performs all of the timing and

counting functions), a 32.768 KHz quartz crystal (which provides a stable time

reference) and a 5 1/2-digit LCD readout. The SUB-CUB-T has 4 Control

inputs which when set either high or low, determine the mode of operation. The

BP and WINK outputs can be used to select either no decimal point, or a

decimal point in the first or second position. The SIGNAL input is used to

activate the timer (when in the timing modes) or to increment the counter (when

in the counting modes).

MOUNTING & DIMENSIONS

Snap-in mounting onto P.C. Board is facilitated by two, split, lock-ramp pins

which engage mounting holes drilled into the P.C. Board. The silicone rubber

elastomeric connectors compress to accommodate P.C. Board thickness

variation of ±0.005”.

P.C. BOARD LAYOUT

P.C. Board pads may be gold or tin-lead plated. Pad surface

must be flat without excessive tin-lead build-up. (Layout view is

from SUB-CUB-T mounting side of board.)

Pad area must be clean and free of contaminants so that

proper electrical contact can be made.

Note: All hole size tolerances ±0.003” ( 0.08 mm)

All other tolerances ±0.005” (0.13mm)

The SUB-CUB-T is ideal for internal “on board” applications where a

readout of elapsed time or count is needed within a circuit enclosure for

maintenance, diagnostic, or other data readout requirements. It can also be

mounted with a convenient bezel kit to provide a very flexible and economical

panel instrument.

The SUB-CUB-T snap-mounts directly onto any 1/16” P.C. Board that has

been etched to provide a mating interconnect pad pattern with two mounting

holes and a polarizing “key” hole. Interconnections to the P.C. Board, as well as

the internal connections, are made with elastomeric connectors that provide a

corrosion-proof, gas-tight, interface contact for high reliability.
