TACHLINK • TACHLINK is a Windows-based program developed to simplify programming, communication and monitoring with the new generation of AI-TEK tachometers via USB2.0 or RS485. • Programming is much faster and simpler with TACHLINK. • Tachometer configuration databases can be stored, backed up and retrieved easily. A stored database can be used to program multiple tachometers and can be e-mailed to remote locations. • The TACHLINK graphical user interface allows any PC to be used as a remote display. • Analong output calibration is available only through TACHLINK and allows the customer to...

TACHPAK® 10 & 30 Digital Process Tachometer Part Number Series T77510 & T77530 RoHS T77510 AI-Tek Instruments, Cheshire, CT USA Wide range of AC or DC power (12-30 Vdc, 80-264Vac 50-60Hz) Greatly improved instrument accuracy, processing speed and response time. Frequency, period or counter modes. User-defined inputs for logic level, averaging, alarm set points and hysteresis, Signal normalization and math functions allow mathematical manipulation of input signals. Results can be displayed along with user-defined units. Accepts sinusoidal and square wave inputs as found in variable...

Programming Features (continued): case of tachometer instruments embedded in explosion proof or NEMA 4X enclosures, remote ac- cess solves the problem of programming by making use of an IR link to allow full front panel control • TACHLINK®: PC / Windows-based custom software allows the user to program all configurable attributes of TACHPAK by PC via a USB2.0 or RS485 connection. In addition, the PC can be used to display data, perform security functions, diagnostics, analog output calibration and real-time data logging; all available through the TACHLINK. Fast response overspeed...

Connection to 12-30 Volt In is also available on the bottom of TACHPAK 10 & 30. A special DIN rail power bus adapter is available as an accessory and works with the accessory power supply.
