The R1 module provides 1 relay output to M Series panel meters.
Up to a maximum of 3 R1 modules can be installed in a single instru-
ment (3 relays).
Note : for more than three relays per instrument or larger relay den-
sity per module, see special modules R2, R4 and R6 at section 2.6.
Relays with 3 contacts each (common, normally closed, normally
open), with switching capability up to 250V @ 8A.
Modules R1 are configured from the ‘ALr1’, ‘ALr2’ and ‘ALr3’ alarm
menus of the panel meter. The ‘ALrX’ menus provide configuration
for main setpoint, hysteresis, independent activation and deactiva-
tion delays, and a second setpoint to create windowed alarms.
Modules r1 are installed on slot ‘Opt.1’, ‘Opt.2’ or ‘Opt.3’
tion 1.15) and are configured from instruments front keypad.
the r1 module can be ordered pre-installed into a M Series panel
meter, or standalone for delayed installation, as they do not require
soldering or special configuration.

Signal
the AO module provides 1 analog output with 4/20 mA or 0/10 Vdc
configurable output range. Output current loop configurable as ac-
tive (the instrument provides the excitation for the loop) or passive
(the loop is externally powered). Signal output proportional to the
instruments reading. Fully configurable scaling, in direct (positive
slope) or inverse (negative slope) scaling.
Up to a maximum of 3 analog output modules can be installed in a
single instrument, all outputs isolated between them and isolated
from the power and input signal circuits.
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 1.15).
The RTU module can be ordered pre-installed into a M Series panel
meter, or standalone for delayed installation, as it does not require
soldering or special configuration.
