FEMA ELECTRÓNICA . Series K . K40-232
27
Output ranges 4/20 mA active, 4/20 mA passive 0/10 Vdc
Accuracy (at 25 ºC) <0.1% FS
Isolation 1000 Vdc
Slots allowed ‘Opt.1’, ‘Opt.2’, ‘Opt.3’
2.3 Module SSR
The AO module provides 1 analog output with 4/20 mA or 0/10 Vdc
configurable output range. Output current loop configurable as ac -
tive (the instrument provides the excitation for the loop) or passive
(the loop is externally powered). Signal output proportional to the
instruments reading. Fully configurable scaling, in direct (positive
slope) or inverse (negative slope) scaling.
Up to a maximum of 3 analog output modules can be installed in a
single instrument, all outputs isolated between them and isolated
from the power and input signal circuits.
Configuration from instrument front keypad, through menu entries
‘Opt.1’, ‘Opt.2’ or ‘Opt.3’, depending on the position the module is
installed.
The RTU module can be ordered pre-installed into a Series K panel
meter, or standalone for delayed
installation, as it does not require
soldering or special configuration.

The SSR module provides 1 output to control SSR relays, to install at
digital panel meters from Series K, up to a maximum of 3 SSR con -
trols in a single meter.
Configuration is performed from the frontal keypad of the meter, by
setting the parameters at the alarm menu. Check the parameters of
at the alarm menu for full information.
The module pr15 Vdc voltage and up to 45 m
