4-20 mA 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
S3 at 2-3, 4-5 and 6-7 for this type of configuration (pin 1 being next to
S3).
