JAQUET FT 3000 overspeed protection Module Overview The FT 3000 is comprised of modules that are configured in a 19“ rack to suit the particular application. A measurement channel may be just a FTFU 3024 motherboard or a combination of motherboard + FTV 3090 relay card + FTW 3013 analog card. FTFU 3024 Motherboard Overview One per channel (sensor). Performs measurement and watchdog functions. 3 hardwarespeed limit monitors for fast over speed detection plus one comparator for acceleration limit. 3 single contact change over relays for status or limits. 3 test generators for on line testing....

FTBU 3034 Trip chain control card Overview Combines 6 different trip commands to provide global shutdown control. 6 potential free change over relay contacts (K1-6) are created from 6 opto-couppled inputs (IN1-6) in a 1:1 relationship. An additional output (OUT) comprises of two relays that each provide a change-over contact. These contacts allow 2 out of 3 voting in a three FTBU 3034 card system. The OUT output is driven by a logical combination of six inputs: OUT is active (de-energized) when the following equation is true. IN1 & IN2 + IN3 & IN4 + IN5 + IN6 - where INi means an active...
