Ai Tek Instruments T77510-10 Tachometer Speed Switch

AI‑Tek's T77510‑10 TachPak 10 Tachometer Speed Switch is a panel‑mount tachometer that measures rotational speed and provides two built‑in relays for speed‑based output switching. It accepts either 80–264 VAC or 12–30 VDC input power, enabling flexible installation in mixed electrical environments. A USB/TACHLINK interface enables quick configuration and on‑board monitoring without removing the unit from the panel. As part of the TachPak 10 family, the T77510‑10 emphasizes tachometer functionality with two mechanical relays and does not include RS485, analog output, or infrared remote compatibility. It is designed for standard, non‑explosion‑proof enclosures, making it suitable for general industrial panels and machine control tasks. Typical uses include monitoring pump or motor speed and triggering alarms or downstream equipment when a set RPM is reached, controlling conveyors, or providing a simple speed switch for automated processes where robust, time‑tested tachometer performance is required.
