About your speed switch
WARNING
When the SST-2000A/H Series Speed Switch/Transmitter is
used as the primary overspeed shutdown device, it must be
tested regularly.
The SST-2000A/H series is a speed switch and signal transmitter that provides
alarm set points for over- and underspeed control for sequential, startup, and
shutdown switching for:
t
engines
t
machines
t
I/P drivers
t
instrumentation
t
process control
t
recording
t
measurement
How it works
The SST-2000A/H accepts a full-scale frequency input value from 0–0.1 Hz
(6 pulses per minute) to 0–50,000 Hz. Standard: 0–80 Hz to 0–20,000 Hz.
Examples of input devices include:
The speed switch converts frequency input (speed, rate) into linear proportional
dc outputs:
It provides 0, 2, or 4 relay trip set points (depending on the model)
t
passive or active magnetic pickups
t
shaft encoders
t
contact closures
t
flow meters
t
photocells
t
0–1 mA (standard - meter out)
t
4–20 mA (standard - proportional out)
t
0–5 Vdc (switch selectable)
t
0–10 Vdc (switch selectable)
