Output Loop-Powered Operation
(Factory Setting)
The 4-20 mA output is factory set for loop-powered operation and
requires a power source of 12 Vdc to 30 Vdc. The overall impedance
depends on the voltage supplied at the 4-20 mA loop. Set jumpers on
JP4 at 2-3, 4-5 and 6 for this type of configuration.
