The SUB- and SCUB1LV (3.3 V) can be treated like an I.C. The module contains a custom CUB 2, with its larger display, can also be mounted with the convenient bezel counter/driver chip that performs all the counting functions together with a kit to provide a very flexible and econmical panel instrument. 6-digit LCD readout. The latchable display with the separate reset function SUB-CUBs snap-mount directly on any 1/16 P.C. board that has been etched permits the module to be used as frequency or rate meter, timer, phase-angle or to provide a mating interconnect pad pattern with two mounting holes and a pulse width indicator and for other complex readout requirements in addition to polarizing key hole. Interconnections to the P.C. Board as well as internal simple high speed counting. connections are made with elastomeric connectors that provide corrosion-proof, The module is ideal for internal on-board applications where a readout of gas tight, interface contacts for high reliability. count, frequency, time, etc. is needed within a circuit enclosure for MOUNTING & DIMENSIONS DIMENSIONS SUB-CUB2 Snap in mounting on the P.C. Board is facilitated by two, split, lock-ramp pins In Inches (mm) which engage mounting holes drilled in the P.C. Board. The silicone rubber elastomeric connectors compress to accommodate P.C.

RESET (R) - CMOS, Schmidt Trigger counter is reset to zero when input is low. Counter should always be reset to zero whenever power is first applied T TEST to the unit. LATCH (L) - CMOS, Schmidt Trigger when pulled low, the latches are R transparent and display is updated as new counts are received. When latch RESET input is pulled high, the display registers count existing immediately prior to activating the latch. COUNT PULSES C TEST (T) - CMOS, Schmidt Trigger Input must be connected to V .
