APPENDIX “B” - SPECIFICATIONS & DIMENSIONS
1. DISPLAY: 6-digit 0.56" (14.2 mm) High LED display.
2. POWER REQUIREMENTS:
AC Versions
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 and count values (except Counter Load values) when power is
removed or interrupted.
Power Cycles (ON/OFF): 100,000 minimum
Data Retention: 10 yrs. minimum
5. INPUTS 1 AND 2: 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
-46-
Hi Bias - Input trigger levels V
IL
= 5.5 V, V
IH
= 7.5 V
Note: Bias levels given are ±10% @ 12 VDC. They vary proportionally with
sensor supply voltage at “DC OUT” terminal.
6. MAGNETIC PICKUP INPUT:
Sensitivity: 150 mV peak (typical @ 12 VDC)
Hysteresis: 100 mV
Input impedance: 26.5 KΩ @ 60 Hz
Maximum Input Voltage: ±50 Vp
7. RATE ACCURACY AND REPEATABILITY: +0.012%
8. RATE MINIMUM INPUT FREQUENCY: 0.03 Hz
Note: At frequencies below 0.03 Hz (1 pulse every 32 sec.) the rate display will
go to zero.
9. CONTROL INPUTS:
Reset - Active low (V
IL

mA), activation and de-activation response time = 10 msec.
Program Disable - Active low (V
IL
= 1.5 V max.), internally pulled up to +5
VDC (I
SNK
= 1 mA).
Print Request - (Serial Communications) Active low, (V
IL
= 1.5 V max.),
internally pulled up to +5 VDC (I
SNK
= 1 mA).
