4-20 mA:
Twelve bit, internal power, can span negative to positive flow/energy rates.
Energy Meter Model Only: Auxiliary Total Pulse Option: Opto isolated open collector transistor. 16 Hz
maximum, pulse width of 30 mSec (fixed).
Flow Meter Model Only:
0…1000 Hz: open-collector, twelve bit, can span negative to positive rates;
square-wave or turbine meter simulation outputs.
Two Alarm Outputs: Open-collector, configure as rate alarm, signal strength
alarm or totalizer pulse. When configured as a totalizing pulse the pulse width
is 100 mSec with a 1 Hz maximum frequency.
