2. Output and control modules
2.1 Module R1
The R1 module provides 1 relay output to to install at digital panel
meters from Series S, up to a maximum of 2 relays in a single meter.
Note : for more than 2 relays per instrument or larger relay density
per module, see special modules R2 and R4.
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.
Relay with 3 contacts (common, normally open, normally closed)
with up to 250 Vac switching voltage and 8 A.
Modules R1 can be ordered pre-installed into a Series S digital panel
meter, or standalone for delayed installation, as they do not require
soldering or special configuration.

2.2 Module T1
The T1 module provides 1 transistor output to install at digital panel
meters from Series S, up to a maximum of 2 transistors 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.
Transistor output is optoisolated, provides 2 terminals for connec-
tion, and can switch up to 35 V and 50 mA.
Modules T1 can be ordered pre-installed into a Series S digital panel
meter, or standalone for delayed installation, as they do not require
soldering or special configuration.
