A 2-digit preset decade counter with a 2-digit light emitting diode decimal readout.
The NL603 Counter is a 2-digit preset decade counter with a 2-digit light emitting diode decimal readout. The counters can be externally reset and gated; they can be operated in one of three modes:
A pulse occurs at the output when the count equals the preset number (Free Run and Preset-Reset modes). A high logic level appears at the output during counting in the Preset-Stop mode. Up to 3 NL603 Counters can be cascaded to give arbitrarily large counts. Carry, reset and preset logic signals are automatically relayed to adjacent Counters through rack edge connectors when the Counters are cascaded.
NL603 modules can be used for digital control of pulse width, cycle duration, pulse delay (phase), number of pulses in trains, etc. Precision obtainable when used with the NL304 Period Generator is better than 0.01% in minimum steps of 1 µsec. The LED display of the NL603 enables it to be used to count responses, number of stimuli delivered, etc., in addition to controlling pulse trains.
