Main Features

●The EDA9081 counting/frequency measurement module can measure: 2 frequency or pulse counting input signals.

●The EDA9081 module can be widely used in various industrial control and measurement systems. It can measure power frequency, flow measurement, transmitter pulse output measurement, etc. Its output is in 485 bus mode, and the ASCII instruction set is compatible with modules such as NuDAM and ADAM. It can be hung on the same 485 bus as control modules from other manufacturers, making it easy for computer programming.

●The functions and technical specifications are as follows: Input signal: Input: 2 independent optoelectronic isolated inputs.

●When applied to counting: pulse width>100 uS, signal high level 5V~24V. Maximum count value: FFFFFFFFH.

●When used for frequency measurement: the frequency range is 0.01Hz-3 KHz, and the input voltage range is 0.5-1.5 times the nominal range.
