SIGNAL PROCESSOR FOR FLAME MONITOR SYSTEM
|
|
 |
GENERAL DESCRIPTION
The IRIS Model P522 is a state of the art flame signal processor. It is
designed to be used with the IRIS S5xx, S55x and S55xB series of Viewing
Heads.
The IRIS Model P522 shares the same electrical specifications as the
IRIS Model P520, however, it is a panel mounted device, whereas the Model
P520 is rack mounted.
Removable wiring connectors are provided to facilitate installation, and
provide ease of removal of the unit if required.
In addition to the four LED's on the front panel, a digital readout and
bar graph provide constant and concise information on the system
status.
The front panel also provides a number of controls for setting up and
operation of this microprocessor based flame monitoring signal processor.

LOCAL OR REMOTE PROGRAMMING
CAPABILITY: |
It is possible, for example, to program the
FLAME ON and FLAME OFF set-points locally (from the front panel) or remotely
(from a host computer) using FlameTools 95/NT software.
The P522
communicates with the remote computer through its RS-422 to RS-232 converter
at either 4800 or 9600 baud selectable at the P522 processor front panel. |
| APPROVALS: |
| The IRIS Model P522 Signal Processor has FM
(Factory Mutual) approval and CSA (Canadian Standards Association)
certification. |
