32-channel Isolated Digital Input Module with 16-bit Counters

ICPDAS Digital I/O Module I-87040PW offers 32 channels for digital input, each of which features photo couple isolation. Moreover, you can choose sink type or source type input by wire connections. All channels are able to be used as 16-bit counters. I-87040W also has 32 LED indicators for channel status. 4 kV ESD protection and 3750 Vrms intra-module isolation are no doubt the standard of I-87040W. Paired with a daughter board like DN-37-381-A, ICPDAS Digital I/O Module I-87040PW makes wiring easier than ever!


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
