Dynalco Speed Switches and Transmitters are available in several versions including magnetic pickup powered. Some have proportional outputs for remote reading or powering external devices.
 SST-2000A and SST-2000H Series Speed Switch/Transmitter
SST-2000A and SST-2000H Series Speed Switches/Transmitters receive signal input from a passive or active magnetic pickup, shaft encoder, contact closure, flowmeter, etc., to provide proportional analog outputs and either 0, 2, or 4 relay trip setpoints.
Features:
- The ultimate in Over/Under Speed Protection for your rotating equipment
- The SST-2000A/H Series Speed Switch/Transmitter is available in six variations:

 SW-200B Speed Switch
Features:
- over/under speed protection
- crank disconnect
- speed monitoring
- transmitter
- 3 relay setpoints
The SW-200B provides reliable engine overspeed protection. It has three adjustable relay setpoints: number one is overspeed. Uses for the two auxiliaries include crank disconnect, generator field-flashing, and speed monitoring. Setpoints are field-programmable and can be tested without overspeeding. Housing is gasketed and sealed.
 SW-50 Speed Switch
Features:
- overspeed protection
- alarm
- 2 relay setpoints
The SW-50 Speed Switch provides reliable engine overspeed protection and is fully field- programmable.
The SW-50 Speed Switch has two relay setpoints: one overspeed plus one auxiliary for crank disconnect, generator field-flashing, or other alarm.
 F-16 Signal Generator/Counter/Calibrator
Used to calibrate tachometers, digital speed indicators, governors, counters, frequency meters. Measures signal frequency from magnetic pickups, pulsers, ac generators, shaft encoders. Eliminates the need for a frequency counter or an audio generator.
