Tips for Choosing the Right I/O Modules for Your Controllers |
|
|
|
|
|
Recently ICP DAS has launched many new PAC (Programmable Automation Controller) products. Meanwhile, ICP DAS also provides a wide range of I-8K and I-87K I/O modules as add-on functions for this series of PACs. It must be really exciting to see them right away in front of you! At the moment, ICP DAS re-categorizes those I/O modules and controllers on our website, and gladly provides several useful suggestions for you so that you could easily and clearly choose which suits you most or what makes the best combo for your projects! |

- For users who use our new PACs, like XPAC, WinPAC, iPAC, and LinPAC, please choose the high profile modules to match your controllers! Modules with the letter ˇ§Wˇ¨ behind the module name are represented as the high profile modules, such as I-8017W and I-87042W.
- For users who use our former PACs, like WinCon, LinCon, and i-8000, please choose the low profile modules to match your controllers. Modules with the normal module name are represented as the low profile modules, such as I-8054 and I-87063.

Differences between I-8K and I-87K I/O modules:
There are two types of I/O modules, ˇ§Parallelˇ¨ and ˇ§Serialˇ¨, categorized by the bus they use to transmit data, and respectively presented as I-8K and I-87K. The parallel modules (I-8K Series) feature high-speed data transmission rate and support MCU (Main Control Unit) only. The serial modules (I-87K Series) with lower data transmission rate feature data preprocessing and support both MCU and I/O expansion units.
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 the same module number also have same I/O channels. For example: I-8054 and I-8054W both has 8 DI and 8 DO. Except I/O channels, other specifications could be different. You have to double check whether the specification suits your application. For example: For I-8054W, its DI logic high level is +10~+50V; but for I-8054, it is +3.5~+30V. |

Note. 1
We list a table below. For the left column, there are several High-profile modules that were released before without a ˇ§Wˇ¨ letter behind their modulesˇ¦ name. Today, ICP DAS would like to unify the recognition of all high-profile modules, so we add a ˇ§Wˇ¨ letter behind them, and we also list them in the right column for your instant comparison. Most important of all, the modules in the left column are totally identical to the ones in the right column; only their names are different now. For users who ever bought the modules in the left column, please feel free to use them! |

Note. 2
Since all high-profile modules are now designed in gray color, ICP DAS would like to unify their module names without ˇ§-Gˇ¨ behind; for example, the module, I-8017HW-G, becomes I-8017HW.
