MODEL 714
Designed for industrial users the Model 714 bi-directional counter has all the features the true professional demands in a solid state counter. Schmitt trigger counting inputs, large easily read LED display, heavy duty construction, and gold plated I/O contacts. The standard unit counts from a variety of count configurations including single count source with direction select line, dual count source with one input being the up count and the other the down, and optional quadrature count input configuration available. Various signal levels and types can be counted, from as low as a 150 mV zero crossing sine wave up to 115 volts, and form "C" or form "A" contact closure. Optional three state BCD outputs allow paralleling of other BCD data on the same lines to simplify external wiring. Presetting is done on the BCD input/output lines. BCD outputs go to a high impedance state when preset command is received. The preset point can be a positive or negative number and unit will count up or down from the preset point. Through zero direction sensing and indication is automatic, i.e., unit counts down to zero with a positive sign and at zero switches to a negative sign and starts counting up. When counting up through zero from a negative direction the negative LED goes out when passing through zero and the unit starts counting up with positive indication.

SPECIFICATIONS
Accuracy:

ą .1 count @ -20 to +60° Celsius

Display:

4 or 6 digits, .56" high-efficiency red LED dot for negative polarity and overrange. Decimal points programmable via solder pads behind front panel lens.

Front Panel Controls:

Three pushbutton switches, one each for start, stop, and reset. If ordered as presettable unit the reset button becomes a preset button.

Remote start/stop/reset:

Requires closure to logic common or TTL logic zero. Input loading 1 LPTTL load. Stop signal overrides start.

Latch:

(01 option only) Requires TTL logic zero or closure to common. BCD data is held as long as latch line is held low. Does not affect count accumulation. Input loading 1 LPTTL load.

Store Display:

Requires TTL logic one or closure to logic 5 volts. Display will be held as long as store line is held high and will update when store is allowed to go low again. Does not affect count accumulation. Input loading 1 LPTTL load.

Parallel BCD:

For presetting, must be three state or diode isolated. Input loading 1 LPTTL load.

Three State Control:

1(01 option only) Requires TTL logic zero or closure to logic common. Forces all BCD outputs to a high impedance state. Does not affect data stored in latches. Input loading 1 LPTTL load.

Sine wave/pulse count input:

(option -08) Minimum signal 150mVRMS, DC to 10Khz. 500mVRMS, DC to 50Khz. Maximum signal 115VAC without damage to circuitry. Input impedance 100Kohm. Threshold adjustable from the front panel with a small screwdriver.

TTL Level Inputs:

Schmitt trigger with no limit on rise or fall time of input pulse. Maximum count rate 100Khz. Input loading 1 LPTTL load.

Contact Closure Inputs:

Accepts form "C" closure input standard but can be modified to accept Form "A" closures by adding filter capacitors on N.O. count input to limit count rate to maximum rate expected. For instance for a count rate of 20hz a 1ľf capacitor is required between the N.O. input and logic common with the N.C. input tied to logic common. Can be factory installed.

Polarity Preset:

Requires logic one for positive and logic zero for negative. Can only be preset when unit is programmed for preset operation and reset is activated. Input loading 1 LPTTL load.

BCD:

Three state + 8421 TTL compatible. Fan out of 4 TTL loads. (Optional)

Carry Output:

Normally high goes to logic zero during count of 1,000000 when counting up. Fan out of 1 LPTTL load.

Borrow Output:

Normally high goes to logic zero during count of 1,000000 when counting down. Fan out of 1 LPTTL load.

Reset Output:

Normally low, goes high for overrange. Fan out of 1 LPTTL load.

Power Interrupt:

Normally a logic level one, goes to logic zero after return of power following power interruption. Fan out of 1 LPTTL load.

Polarity Output:

TTL logic one for positive and logic zero for negative. Fan out of 1 LPTTL load.

Operating Temperature Range:

-20° to +60° Celsius.

I/O Method:

Card edge connectors with solder tabs.
