2. Output and control modules
The R1 module provides 1 relay output to install in large for -
mat industrial meters from Series B. Formats B26 and B46 ac -
cept up to 3 relays, and formats B24 and B44 accept up to 2
relays.
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 R1 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
1.6
on how
to install output and control modules.
