ICPDAS Counter/Frequency Module I-8084W is a 32 bits (hardware) high speed Counter/Frequency/Encoder I/O with “Up Counter”、"Frequency”、 “Up/Down Counter”、 “Dir/Pulse Counter” and “A/B Phase Counter” mode.


With different communication interface, the I/O modules can be classified to high communication speed (Parallel bus) 8K series modules and low communication speed (serial interface) 87K series modules.


There are two types of I/O modules, Parallel and Serial. The parallel modules (I-8 Series) are high-speed modules and support MCU (Main Control Unit) only.

High Profile VS Low Profile

With different form factor, I/O modules can be classified to high profile and low profile. Basically, high profile and low profile modules that with same item number also have same I/O channel number.

For example: I-8054 and I-8054W both has 8 DI and 8 DO.

Except I/O channel number, other specifications could be different. You have to double check whether the specifications suit your application.

For example: For I-8054W, its DI logic high level is +10 ~ +50V. But for I-8054, it is +3.5 ~ +30V

Minimum Pulse Width 2 μs
Input Frequency 1 Hz ~ (typically) 250 kHz (both counter mode and frequency mode)
(where 250 kHz is calculated as followings:
supposed that duty cycle = 50%, refer to Minimum Pulse Duration of High Level, we have pulse period = 2 μs x 2 = 4 μs, which is 250 kHz as a maximum)
Maximum Frequency:
refer to Minimum Pulse Duration of High Level, maximum frequency is highly affected by duty cycle
Frequency Accuracy = ±0.4 %
Isolated Voltage 1000 Vrms
ESD Protection 2 kV (Contact for each channel)
