Details

ICPDAS Counter/Frequency Module I-87084W is a 32 bits hardware high speed Counter/Frequency/Encoder Input Module with "Up Counter", "Frequency", "Up/Down Counter", "Dir/Pulse Counter" and "A/B Phase Counter" mode.

ICPDAS Counter/Frequency Module I-87084W can has variety mode combination for all 8 channels. That means it can use some channels as “Up Counter” and others as "Frequency" or "A/B Phase".

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

Isolated Input Level

On Voltage Level	3.5 VDC ~ 30 VDC
Off Voltage Level	1 VDC Max.

TTL Input Level

On Voltage Level	2 VDC ~ 5 VDC
Off Voltage Level	0 VDC ~ 0.8 VDC

Input Frequency

TTL Mode	1 Hz ~ (typically) 500 kHz (both counter mode and frequency mode) (where 500 kHz is calculated as followings: supposed that duty cycle = 50%, refer to Minimum Pulse Duration of High Level, we have pulse period = 1 μs x 2 = 2 μs, which is 500 kHz as a maximum)
Isolated Mode	3.5 V ~ 10 V: 1 Hz ~ (typically) 200 kHz 10 V ~ 30V : 1 Hz ~ (typically) 150 kHz
Maximum Frequency	Refer to Minimum Pulse Duration of High Level, maximum frequency is highly affected by duty cycle Frequency Accuracy = ±0.4 %
