AI‑Tek's TACHTROL 30 digital tachometer, model T77630‑40 in a NEMA 4X enclosure, is a dual‑channel, panel‑mount instrument that measures input frequency from two independent speed sensors and presents the result on a front‑panel LCD display. It provides an analog output, USB connectivity, and utility RS‑485 communication, and includes two mechanical relays and two solid‑state relays for control tasks, with TACHLINK software enabling front‑panel programming and remote display options. The unit supports wide power options (AC 80–264 VAC or DC 12–30 VDC) and is designed for robust environments demanding reliable speed measurement and control.
