Alarm Monitoring Systems
Spare parts local inventory
Repair service for electronic cards and components
Technical service through original manufacturer engineers
Main Characteristics:
- 6, 12, 24, channel cards
communicating
simultaneously with a
Central Monitor Card.
- Response time less than
0,8 s programmable up
to 60 s.
- Threshold and rate alarms
can be configured as
required to operate either
of
two common alarm relays
supplied as standard.
These relays are
connected
directly to the
internal bus system and
are therefore immune
|
Alarm
Monitor Series 4000
 |
from any failure of the monitor card or
even its incomplete removal from the
system
- The 4400 offers maximum user control in defining how relays will
operate on
alarm. By this means, relay outputs can be grouped by
function to provide
selective closures to external devices such as
PC's, PLC's, DCS's, or
annunciators. They can be configured for
reflash or klaxon sequences,
depending on the application. Two
relays can also be optionally fitted to
any channel card to provide
per-points contacts.
- Optional DC analogue re-transmission output per channel. 0 to
10mA, 0 to
20mA, 4 to 20mA; Accuracy 0,1% span. Output either
directly proportional
to input signal or linearised to temperature,
using International Standard
sensor characteristics, or linearised
to a user-entered characteristic.
- Up to 1 A at 24 VDC available on rear terminals for powering
transmitters.
Protecting by self re-setting fuse.
- Dead band: adjustable 0 to 25% of span in 1% increments
individually for
each set-point. |
Internal Clock
- Internal log-book for event registrations.
Possibility to visualize on the
display all past events.
Self-analysis
- Internal diagnostic system for fault
self-identification.
Flexibility
- Menu configuration
- Fully configurable form the front panel. (Possibility to copy channel
configuration from channel to channel)
- Password
- The measured variable for any selected channel is displayed with
engineering unit annotation and user-tagging where appropriate. Alarm
set-point information is also continuously shown. If desired, a display
scanning sequence can be initiated, with user control of speed and channel
to be displayed.
- "Reset relay" function
External
Interfaces
- Optional serial connection (RS232 o
RS485) to an external PC for data
downloading.
