Introduction
The T24-PA pulse acquisition module is a high
performance PCB designed for the collection and
processing of pulse related measurements. This
includes measuring the period between pulses to
provide outputs in Hz, RPM and Time as well as actual
pulse counting.
Miniature in size, the device transmits on license-free
2.4Ghz, avoiding local radio interference to ensure data
integrity and security.

Data is provided in real time at variable speeds with a
direct line of sight range of 100 or 200 meters which can
be extended with the use of high gain antenna’s and
repeaters.
The module’s transmit to a range of receivers including
handheld indicators, digital displays, analogue and serial
outputs, PC display and wireless printer (please see
separate sheets) and has various powering options.
Also available in IP rated enclosures.
See T24-ACM, T24-ACMi and T24-ACMm.
