FEMA ELECTRÓNICA . Series K . K40-232
29
2.7 Module S2
Protocol ASCII
Bus type RS-232, up to 57.6 Kbps
Isolation 1000 Vdc
Slots allowed ‘Opt.1’, ‘Opt.2’, ‘Opt.3’
2.8 Modules R2, R4, R6
The R2, R4 and R6 modules provide 2, 4 and 6 relay outputs for Series
M panel meters. Relays with 3 contacts each, with switching capabil -
ity up to 250 V @ 6 A.
Modules R2, R4 and R6 are installed on slot ‘Opt.1’
and are config -
ured from instruments front keypad, and provide setpoint configura -
tion, hysteresis, independent activation and deactivation 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, T1 and SSR
modules.
The R2, R4 and R6 modules can be ordered pre-installed into a Series
M 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 Series
M of panel meters. ASCII protocol with ‘Master’ / ‘Slave’ architec -
ture. 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.
The S2 module can be ordered pre-installed into a Series M panel
meter, or standalone for delayed installation, as it does not require
soldering or special configuration.
