The R2, R4 and R6 modules provide 2, 4 and 6 relay outputs for K
Series panel meters. relays with 3 contacts each, with switching ca-
pability up to 250 V @ 6 A.
Modules R2, R4 and R6 are installed on slot ‘Opt.1’ (see section 1.23)
and are configured from instruments front keypad, and provide set-
point configuration, hysteresis, independent activation and deactiva-
tion delays, and second alarm setpoint for windowed alarms.
Only one module R2, R4 or R6 can be installed per instrument. Mod-
ules R2, R4 and R6 are not compatible with standard R1 modules.
The R2, R4 and R6 modules can be ordered pre-installed into a K
Series panel meter, or standalone for delayed installation, as they do
not require soldering or special configuration.
The S2 module provides a RS-232 communications module for K
Series of panel meters. ASCII protocol with ‘Master’ / ‘Slave’ archi-
tecture. Addressable with up to 31 modules. Frames codified in rep-
resentable ASCII characters (codes 32 to 255), directly visible using
‘hyperterminal’ or similar programs.
• Access to display values, alarm status, memory of maximum and
minimum, alarm setpoints, ...
Configuration from instrument front keypad, through menu entries
‘Opt.1’, ‘Opt.2’ or ‘Opt.3’, depending on the position the module is
installed (see section 1.23).
The S2 module can be ordered pre-installed into a K Series panel
meter, or standalone for delayed installation, as it does not require
soldering or special configuration.
