FEMA ELECTRÓNICA . SERIES B . Models Bxx-C1
2. Output and control modules
2.1 Module R1
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.

2.2 Module T1
The T1 module provides 1 transistor output to install in large
format industrial meters from Series B. Formats B26 and B46
accept up to 3 transistor outputs, and formats B24 and B44
accept up to 2 transistor outputs.
Configuration is performed from the front keypad of the in-
strument, by setting the alarm parameters. Check the alarm
