FB230A工業(yè)自動化與控制的監(jiān)控器-繼電器輸出規(guī)格書PDF中文資料

Description

The FB Series is used to monitor the operation of one twolamp

incandescent beacon and one beacon flasher (or auxiliary

module). The flasher and lamps are monitored by sensing the

flow of current in the circuit. If the lamp(s) or the flasher fail to

operate properly, a solid-state output and an isolated SPDT relay

energize. When connected to a site monitoring system, this

unit provides the remote beacon monitoring protection required

by the FAA/FCC. On a multiple beacon structure, one unit is

required for each two-lamp incandescent beacon (one unit per

beacon for LED beacons).

Operation

If one lamp in an incandescent beacon fails, the relay and solidstate

lamp failure outputs energize after 10s. If the flasher fails

in the ON or OFF condition, the relay and the solid-state flasher

failure output energizes after 6s. If both failures occur, all three

outputs energize after their trip delays.

Note: If both incandescent lamps fail, all three outputs will

energize. The relay and solid-state flasher failure output

energizes after 6s, and the solid-state lamp failure output

energizes after 10s.

Features & Benefits

FEATURES BENEFITS

Toroidal current sensing

Reliable low cost monitoring of the flasher and

lamps through built-in CT and provides isolation

from the monitored circuit

Failsafe beacon

monitoring

Alarm monitors for failed incandescent lamps in

addition to flasher function

One isolated, 5A, SPDT

alarm output plus two,

1A, solid-state line

voltage alarm outputs

When connected to a site monitoring system, it

provides the remote beacon monitoring protection

required by the FAA / FCC.

Fixed trip delays for

flasher (6s) and lamp

(10s) failures

Prevents nuisance alarms
