Speed Switches for Industrial Applications
04/06/2026

Speed measurement and protection are foundational to reliable industrial operations. From engines and pumps to compressors and turbomachinery, accurate speed monitoring helps protect assets, improve control, and prevent costly failures.

Dynalco’s SST Series Speed Switches and Transmitters are designed to meet these demands across a wide range of industrial applications. Whether you need a proven analog solution or a digitally configurable platform, Dynalco offers a speed switch that matches your system requirements—without unnecessary complexity.

Built for Industrial Reality

Industrial speed sensing environments are demanding. Electrical noise, temperature extremes, hazardous locations, and varying sensor types are common challenges.

Dynalco SST speed switches are engineered with these realities in mind:

  • Broad compatibility with magnetic pickups, Hall-effect sensors, and other speed inputs

  • High accuracy and stable outputs for reliable control system integration

  • Configurations that support simple relay-based protection or advanced monitoring and diagnostics

  • Designs suitable for Class I, Division 2 hazardous locations

  • A long track record in engine, pump, and rotating equipment applications

Rather than forcing customers into a single architecture, Dynalco provides multiple platforms that scale with application needs.

SST7000 Series: Digital Flexibility for Modern Systems

For applications that demand greater visibility, faster response times, and flexible configuration, the SST7000 Series offers a modern digital approach.

Key Characteristics

  • Supports 2‑wire and 3‑wire speed sensors, including magnetic pickups and Hall-effect sensors

  • Wide input frequency range up to 50 kHz

  • High accuracy with isolated 4–20 mA output, plus optional voltage outputs

  • Available with 0, 1, 2, or 4 programmable SPDT relays

  • PC programmable via USB or configurable through the front keypad and LCD display

  • Faster response times with standard 50 ms and optional 10 ms

  • Designed for DIN rail mounting with compact form factor

SST7000 combines speed switching, transmission, and diagnostics into a compact DIN-rail-mounted device that integrates easily into contemporary control architectures.

The SST7000 provides need precision, flexibility, and fast response in demanding speed protection applications. The platform is digitally programmable via USB or a front‑panel keypad, allowing configuration changes without rewiring or hardware modification. High‑speed response options support critical protection requirements, while isolated analog outputs and configurable relay logic simplify integration into modern control systems. Clear local indication of speed, alarms, and setpoints provides immediate visibility during operation and commissioning. This makes SST7000 an ideal choice for speed protection in turbomachinery, critical pump systems, compressors, and high-speed rotating equipment, where precision and flexibility are essential.

SST‑2000 Series: Proven Reliability in Industrial Speed Switching

The SST‑2000 Series remains a trusted choice in industrial environments where straightforward speed switching and analog output are required.

Designed as an analog speed switch and transmitter, SST‑2000 converts frequency or speed signals into clean proportional outputs, while also providing relay-based overspeed and underspeed protection.

Key Characteristics

  • Accepts a wide range of input sources, including magnetic pickups, contact closures, shaft encoders, and AC generators

  • Converts speed or frequency into linear analog outputs such as 4–20 mA, 0–5 V, or 0–10 V

  • Available with 0, 2, or 4 relay setpoints for overspeed and underspeed protection

  • Fully field-adjustable via potentiometers and internal switches

  • No software, firmware, or PC required

The SST‑2000 remains a preferred choice for applications that value simplicity and long‑term reliability. Its field‑adjustable design requires no software, making setup and maintenance straightforward for technicians in the field. The platform supports a wide range of common speed sensors and provides dependable relay logic for shutdown and alarm functions. These attributes make SST‑2000 particularly well suited for legacy systems and fixed‑speed designs. For applications that prioritize robustness, familiarity, and ease of maintenance, SST‑2000 delivers consistent performance with minimal operational overhead.
