Introduction
FV-40 Series Flame Detector
087-0056 REV F
20
1.5.5 Output
Signals
Outputs are available according to the default configuration or the wiring
options selected for the FV-40 series detector. Determine the outputs for
your model according to Table 9.
The detector incorporates several types of output suitable to different
control systems:
0-20mA (stepped) with HART
Relays (Alarm, Fault, Auxiliary)
RS-485 Modbus
Model F4-UF Analog Output – analog output proved ultra-fast detection
to comply with 20 msec detection.
