2.4 Module AO
The AO module provides 1 isolated analog output, configu -
rable for 4/20 mA or 0/10 Vdc, to install on Series M me-
ters, up to a maximum of 3 analog outputs in the same meter.
Output signal is fully scalable, both with positive and nega -
tive slopes, and is proportional to the reading.
The mA output can be configured for active loops (the in -
strument provides the power to the mA loop) or passive
loops (the loop power is external to the instrument).
Configuration from the front key pad, through the ‘Opt.1’,
‘Opt.2’ or ‘Opt.3’ menu entries, depending on the slot where
the module is installed.
The AO modules can be supplied already installed into a Se -
ries M panel meter or as a standalone module. The installa -
tion requires no soldering or special configuration.
The SSR module provides 1 output to control an SSR relay, to
install on Series M meters, up to a maximum of 3 SSR outputs
in the same meter.
Configuration from the front key pad, through the alarms
menu of each instrument. For more information see the
‘alarm’ section at the user’s manual.
2 terminal output, with +15V @45mA drive.
The SSR modules can be supplied already installed into a Se -
ries M panel meter or as a standalone module. The installa -
tion requires no soldering or special configuration.
