ACTIVE AND PASSIVE SIGNALS
The instrument can be configured to measure process signals in 4/20 mA (active and passive) and 0/10 Vdc. The instrument has two outputs :

output 1 is always fixed to 4/20 mA (active and passive).
output 2 can be configured for 4/20 mA (active and passive) or 0/10 Vdc.

To select the ‘active’ or ‘passive’ mA versions at the input and output signals, configure the connection terminals according to your needs.

active mA inputs are powered by an external element, and the instrument receives an active mA signal.
passive mA inputs are powered by the instrument, by using the +15 Vdc (terminal 7) to power the transducer.
active mA outputs are powered by the instrument.
passive mA output are powered by an external element and the instrument only controls the value of the mA, but it does not provide power to the output loop.
