CONTROL CARDS
The new generation System 57 control
cards provide display and alarm
facilities for the full range of Sieger gas
detectors.
Their concise, backlit, multi-part LCD
displays the gas reading and status in
both analogue bargraph and digital
numeric forms. In addition, there is an
alpha-numeric message section to give
sensor (and engineering function) status.
General
● 3 levels of alarm
● Individual, zoned, voted, master, time
delayed, update and rate of rise
alarm facilities
● Clear 4 part display
● Peak reading capability
● Sensor performance monitoring
5701 CONTROL CARD
This provides a single channel control
function within a 1“ wide package.
● Independant single channel operation
● Plug-in input and output options
5704 CONTROL CARD
This provides four channels of control
function within a 1“ wide package.
● 4-Channel operation
● Choice of output options
● Channel displayed: automatic
sequencing, highest reading or
combination or manual channel
display selection options
ENGINEERING CARD
The System 57 engineering card
provides full maintenance and set up
facilities for each channel card.
The front panel has a series of tactile
feedback pushbuttons that allow checks
of the alarm levels and performance to
be carried out for each channel. A real
time ‘on board’ clock provides calibration
history and calibration overdue reminder
functions.
● Security protected
● User friendly operation
● Calibration facility
● Command accept/abort facility
● Channel card setup capability
SERIAL COMMUNICATIONS MODULE
The serial communications module
provides a gateway between the System
57 rack and a remote device (DCS, PLC
or SCADA package) to allow the
continuous monitoring of each channel’s
operation and condition as well as
allowing remote configuration of the
system operation.
● Industry standard MODBUS protocol
● RS485/422/232 standard
● Bi-directional
● Isolated communications drivers
● SCADA graphics package available
RS232 PRINTER DRIVE MODULE
The printer module provides a serial
output in the event of a gas alarm, fault
or user intervention.
● RS232 ASCII event data
● Selectable print criteria
● Time and date stamping
● Isolated communications driver
● Rack mounted printer option
ALARM UPDATE MODULE
The alarm update module provides a
common alarm indication with new
alarm event update.
● 2 outputs: 1 relay, 1 Darlington
● Selectable operation: pulsed,
continuous
● Alarm accept input
● Common alarm reset input
● Complies with ISA ‘’M’’, DIN 19 235
● Optional update communication panel
INTERFACE CARD
The interface card provides the link
between the sensors and the control
cards and is available in 7 versions
(5 for 5701, 2 for 5704), with various
relay output options.
● Sensor interface
● Relay options
● Individual control card power option
● High integrity operation option
● Accepts ≤ 2.5mm / 14 gauge cable
DC INPUT CARD
The DC input card provides the
connection point for power supplied to
the whole rack.
The field wiring from the engineering
card modules is also on this card.
● Common power supply wiring point
● Reverse polarity and short circuit
protection
● Multi-supply input capability
POWER SUPPLY UNITS
The power supply units are rack
mounted to complement the System 57
systems.
● 1U high, 19“ & 1/2 19“ units
● Upgradeable
● Auto sensing input voltage; AC or DC
● Regulated DC output
● Over voltage and overload protected
