Overview
133388-01 is the front-card of the 3500/53 overspeed-detection suite.
Each card provides two independent tachometer channels that accept Keyphasor® or magnetic-pick-up signals, measure speed from 0 – 100 000 rpm (±0.1 % accuracy) and compare the result to user-programmable overspeed limits.
Up to three cards can be installed in one rack to build 2-out-of-3 voted overspeed protection that satisfies API 612.

Protection & voting modes
Overspeed – single set-point (API 612)
Speed-band – window alarming (e.g. idle / rated)
Acceleration – rate-of-change limit (rpm/s)
Zero-speed – stand-still confirmation
Reverse rotation – direction change alarm
Peak-hold – stores maxima until reset via software or DI
Why use it
API 670 / 612 compliant – meets petro-chemical and power-industry overspeed rules.
Sub-millisecond response – fast enough for steam-turbine trip relays.
2-out-of-3 voting – build SIL 2/3 protection without external logic.
Wide speed range – 1 rpm to 100 000 rpm with the same card.
Keyphasor sharing – eliminates a separate Keyphasor module in the rack.
Hot-swap – exchange in < 2 min while rack remains powered.
