APPENDIX “B” - SPECIFICATIONS & DIMENSIONS
1. DISPLAY: 6-digit 0.56" (14.2 mm) High LED display.
2. POWER REQUIREMENTS:
AC Power: Switch Selectable 115/230 VAC , ±10%, 50/60 Hz, 20 VA
DC Power: 11 to 14 VDC @ 0.7 amp maximum
3. SENSOR POWER: +12 VDC (±25%) @ 100 mA.
4. MEMORY: Non-volatile E 2 PROM memory retains all programming
information, count values, and Counter Load Values when power is
removed or interrupted.
Power Cycles (ON/OFF): 100,000 minimum
Data Retention: 10 yrs. minimum
5. INPUTS A AND B: Switch selectable to accept count pulses from a variety
of sources including switch contacts, outputs from CMOS or TTL circuits,
and all standard RLC sensors.
Current Sourcing: Unit provides pull-down resistor for sensor with
current sourcing outputs. (Max. input voltage = 28 VDC @ 7 mA.)
Current Sinking: Unit provides pull-up resistor for sensors with current
sinking outputs. (Max. sensor current = 1.6 mA.)
Debounce: Damping capacitor provided for switch contact debounce. Limits
count speed to 100 Hz maximum and input pulse widths to 5 msec. minimum.
Lo Bias: Input trigger levels V
IL
= 1.5 V, V
IH
= 3.75 V
Hi Bias: Input trigger levels V
