Housing:
High impact plastic case with NEMA 4X front
panel.
Dimensions:
See Section 1-5, Page 4.
Display:
8 Digit, 0.55” High, 15 Segment, Red Orange,
LED.
Input Power:
A: 110 VAC ± 15% or 12 to 27 VDC
B: 220 VAC ± 15% or 12 to 27 VDC
NOTE: AC Inputs are internally fused with a
160mA slow blow fuse.
Current:
Maximum 280 mA DC or 5.3 VA at rated AC
voltage.
Output Power:
(On AC powered units only): +12 VDC at 100
mA. Separate Isolated 12 VDC at 100 mA to
allow ± 12 VDC or +24 VDC, regulated ± 5%
worst case.
Temperature:
Operating: +32°F (0° C) to +130 ° F (+54° C)
Storage: -40°F (-40° C) to +200 ° F (+93° C)
(Extended operating temperature range
available, consult factory)
Memory:
EEPROM stores all program, display mode
and count data for a minimum of 10 years if
power is lost.
Reset
Front push button: “CLR” resets displayed
number and control output.
Remote Input (Terminal 5): Open or 0 to 1
VDC (low), 3 to 30 VDC (high), 10K ohm input
impedance to ground. Minimum pulse on /
off time 5 msec.
Accuracy over full temperature range:
Analog - Zero error: ±0.175% full scale max.
Overall error: ±0.5% full scale max.
Digital - 100% (within specifi ed voltage
ranges)
Pulse Inputs:
3A: Standard. High impedance pulse input.
Open or 0 to 1 VDC (low), 3 to 30 VDC (high),
10K ohm input impedance. 20 KHz maximum
speed (min. on / off 25 usec).
3B: Same as 3A except 4.7 K ohm pull up re-
sistor to +5 VDC with respect to Terminal 12.
Analog Inputs:
The current or voltage input is converted to
a highly linear 0 to 10 KHz frequency. This
frequency can then be scaled by 8 digit K-fac-
tors to display rate or count in the appropriate
engineering units.
