ICPDAS I-87024CW
4-channel 12-bit channel to channel isolated current output module with open-wire detection
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
