Open Collector Outputs
OUTPUT
ASSIGNMENT
Two open collector pulse outputs Out 1 and Out 2.
Individually programmable for rate, total, or grand total alarms; rate, total, or grand total pulse
outputs; or retransmitting of pulse inputs; constant timed pulse output; quadrature outputs
(requires Out 1 and Out 2); or off.
RATING Isolated open collector, off: 24 VDC max, on: <1 V @ 150 mA max
ALARM OUTPUT Assign to rate for high or low alarm trip point.
Assign to total or grand total for total or grand total alarms.

ACKNOWLEDGE
Front panel ACK button resets output and screen indication.
PULSE OUTPUT K-FACTOR
(COUNT)
K-factor (couNT) programmable from 0.000001 to 9999999. Rate pulses are generated as a
scaled output of the rate input with one output pulse per K-factor (count) number of input
pulses. Total and grand total pulses are generated for every total or grand total increment
selected. (e.g. K-factor value of 100 will generate one pulse every time the total is incremented
by 100 units)
Rate retransmission pulses one to one for input pulses, up to maximum output speed. K-factor
is not used for retransmitting outputs.
PULSE OUTPUT PULSE WIDTH Unless otherwise stated, pulses are 50% duty cycle for required frequency.
A pulse rate retransmit output will generate 100 to 130 μs pulses at the falling edge of every
input pulse.
PULSE OUTPUT MAXIMUM
FREQUENCY
5 kHz, pulse width at 50% duty cycle.
If the programming of the outputs would exceed 5 kHz, the meter will display pUlse
OVERRNG
QUADRATURE OUTPUT
Output set to quadrature will lag the other pulse output by 90
°
(1/4 duty cycle) at output
frequency. Minimum 1 Hz
TIMER OUTPUT Programmable on and off time, repeating cycle. Minimum period 0.1 second, maximum
100,000 seconds. Minimum pulse time 0.01 second, maximum 10,000 seconds.
