Key Features of Wind Alarm Control System With Alarm Muting Facility

• Alarms can be interfaced with railway track signalling system to automatically prevent passage of trains over the bridge, whenever alarm conditions occur
• The system has facility to mute the alarm, at the discretion of supervisor or through automatic interlock with the track signalling system
• The system is capable of retransmitting wind speed analog data over a secondary loop interfaced with yet another IB-2
• Processes wind speed pulses through two independent paths; analog and digital, giving total redundancy
• Uses a three cup magnetically coupled anemometer.
• Immune to gust or lull from affecting the alarm annunciation.
• Simple and easy controls and an ergonomic design for a fool proof and dependable instrument system.
• Packaged in IP66 enclosure and uses components rated to work up to 65 ° C.
• It can withstand water submergence up to 3 m. and is resistant to corrosion.
• Processes wind speed pulses through two independent paths; analog and digital, giving 100% redundancy.
• In addition it has facility to check and cross refer sensor calibration built in the system.
• The main principle of the system, is based on the proven technology of data transmission over industrial 4-20mA current loop.
• Can be used for retransmission of data repeatedly for further distances in multiples of 5 Km, with no loss of accuracy.
• Loop powered operation isolates the system from dependence on mains
• Supply, usually the first casualty in a thunder storm.
• The instrument operates from a 24 volt battery and is isolated from the battery up to 500V AC.
• The 4-20 mA loop has inherent quality of detecting open or shorted loop conditions.
• In built protection and filters for lightening and lightning induced spikes as well as from accidental 230V AC line leakage.
• Sensor, Electronics hardware and the 24 Volt battery supply are totally isolated from each other.
• Simplicity of operation, provision of minimum important functions and ease of installation
• Provides potential free NC/NO contacts for interlocking with the external track signalling system.
• Provides for foolproof alarm acknowledge, both in normal to alarm and alarm to normal transitions.
• Caters to one sensor with one loop receiver alarm generator at up or down station.
• Can be further expanded by cascading any number of loops in a given direction, say "up".
