APPLICATION FLEXIBILITY VIA RECONNECT OPTIONS
switch increments the counter. The low pass filter (1meg resistor and 4700 pf
cap) used with a Schmidt trigger circuit debounces mechanical switch signals.
The switch load is 14 µA (max. voltage drop 0.5 V) when ON. OFF-state
leakage current must be less than 2 µA.
operate at speeds up to 5 KHz when driven by bi-polar outputs or external
circuits having an output impedance of 3.3 KΩ or less. Input drive voltage
must be limited to 3.0 V maximum to avoid a charging current into the
batteries which can cause premature battery failure or leakage. CMOS and
TTL Logic outputs can be loaded with a resistor (R
a voltage divider can be used as shown for the PNP O.C. Transistor output.

terminal leads in the Input Connector Body. The connector body is polarized to
prevent incorrect insertion, and locked in place by the battery cover to avoid
accidental disengagement. Connectors are supplied with the 3 leads installed as
shown below. A spare blue lead is supplied in the hardware pack.

silver alloy relay contacts with wiping action are usually satisfactory for
generating count input signals. Motor starter contacts, tungsten contacts, and
brush-type contacts should NOT be used.
