General Information
MSA
GB
The Control Units have a display [LCD], backlit for each channel.
Moreover, any time an alarm set-point is exceeded, this is indicated by other pilot lights.
Three alarm set-points are available for each channel with the designations
C [Caution],
W [Warning] and A [Alarm]
, it is possible to use an additional indication of
Overrange
if the full
scale value is exceeded [the display shows EEEE].
The indications of output alarms, which can be transmitted remotely, can be realised via relay con-
tacts, de-energised, or via opto-isolators, depending on the configuration modalities of the
Control Unit.
Passwords and access codes for the various functions prevent accidental or unwanted tampering;
specific messages on the display inform and identify any operational anomalies and any errone-
ous data setting.
The following analogue output signals can be selected as desired with the possibility of also ef-
fecting their linearisation: 0 *20 mA, 4 *20 mA, 20*0 mA, 20*4 mA. Moreover, an interactive serial
interface RS485 is available.
The board is available in four versions:
The 9010/20 LCD boards offer numerous installation solutions for rack mounting, wall mounting
in ABS containers or in anti-deflagration containers for dangerous zones.
The control modules connected to sensors or transmitters that operate in potentially
hazardous zones for detecting combustible gases or oxygen will be configured according
to the operational modalities provided by the ATEX Directive.
