Terminal
plug-in screw clamp, pitch 5.08 mm
Installation allowed at slot 1, slot 2, slot 3
The AO module provides 1 analog output, configurable for
4/20 mA or 0/10 Vdc signal
, to install in large format indus-
trial meters from Series B. Formats B26 and B46 accept up to
3 analog outputs, and formats B24 and B44 accept up to 2
analog outputs.
Output signal is fully scalable, both with positive and negative
slopes, and is proportional to the reading. The mA output can
be configured for active loops (the instrument provides the
power to the mA loop) or passive loops (the loop power is
external to the instrument).
Configuration is performed from the front keypad of the in
-
strument, by accessing the menu entries ‘Opt.1’, ‘Opt.2’ or
‘Opt.3’, according to the slot where the module is installed.
AO modules can be provided factory installed into a Series B
instrument, or standalone for delayed installation. No solder
-
ing or special configuration is required. See section
on how
to install output and control modules.

2.3 Module SSR
The SSR module provides 1 output for SSR relay control, to
install in large format industrial meters from Series B. Formats
B26 and B46 accept up to 3 SSR control outputs, and formats
B24 and B44 accept up to 2 SSR control outputs.
Configuration is performed from the front keypad of the in
-
strument, by setting the alarm parameters. Check the alarm
menu parameters at the instrument user’s manual for full in
-
formation.
Modules SSR can be provided factory installed into a Series B
instrument, or standalone for delayed installation. No solder
-
ing or special configuration is required. See section
on how
to install output and control modules.
