ANNUNCIATORS:

B - Counter B

C - Counter C



- Upper significant digit display of counter

SP1 - setpoint 1 output state

SP2 - setpoint 2 output state

SP3 - setpoint 3 output state

SP4 - setpoint 4 output state

COUNTER DISPLAYS:

Maximum display: 8 digits: ± 99999999 (greater than 6 digits, display

alternates between high order and low order.)

INPUTS A and B:

DIP switch selectable to accept pulses from a variety of sources including

switch contacts, TTL outputs, magnetic pickups and all standard RLC

sensors.

LOGIC: Input trigger levels VIL = 1.5 V max.; VIH = 3.75 V min.

Current sinking: Internal 7.8 KΩ pull-up to +12 VDC, IMAX = 1.9 mA.

Current sourcing: Internal 3.9 KΩ pull-down, 7.3 mA max. @ 28 VDC,

VMAX = 30 VDC.

Filter: Damping capacitor provided for switch contact bounce. Limits

input frequency to 50 Hz and input pulse widths to 10 msec. minimum.

DUAL COUNT MODES:

When any dual count mode is used, then User Inputs 1 and/or 2 will

accept the second signal of each signal pair. The user inputs do not have

the Logic/Mag, HI/LO Freq, and Sink/Source input setup switches. The

user inputs are inherently a logic input with no low frequency filtering.

Any mechanical contacts used for these inputs in a dual count mode

must be debounced externally. The user input may only be selected for

sink/source by the User Jumper placement.

MAXIMUM SIGNAL FREQUENCIES:

To determine the maximum frequency for the input(s), first answer the

questions with a yes (Y) or no (N). Next determine the Count Mode to be

used for the counter(s). If dual counters are used with different Count Modes,

then the lowest frequency applies to both counters.

Notes:

1. Counter Modes are explained in the Module 1 programming section.

2. Listed values are with frequency DIP switch set on HI frequency.
