4-Port RS-232 Module

● High-profile Module
● Serial Port with ±4 kV ESD Protection
● Internal 128-byte Hardware FIFO for each Port
● Baud Rate of up to 115200 bps
● LED Indicators for TxD, RxD and Power Status
● Low power consumption
● Made from fire retardant materials (UL94-V0 Level)

The ICPDAS Communication Module I-8114W provides 4 non-isolated RS-232 serial ports. It is equipped with 128 bytes hardware FIFO for each port, offers speed up to 115.2 Kbps and supports full-duplex communication.


In the harsh industrial environment, the on board ESD protection devices can divert this potentially damaging charge away from sensitive circuitry and protect the ICPDAS Communication Module I-8114W from permanent damage.


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
