Parallel bus (I-8KW) VS Serial bus (I-87KW)
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.
I-8K Series VS I-87K SeriesThere are two types of I/O modules, Parallel and Serial. The parallel modules (I-8K Series) are high-speed modules and support MCU (Main Control Unit) only. The serial modules (I-87K Series) can support either MCU or I/O expansion unit. The difference between the two series are: |
||
|---|---|---|
| Model | I-8K Series | I-87K Series |
| Communication interface | Parallel bus | Serial bus |
| Protocol | - | DCON |
| Communication speed | Fast | Slow |
| DI with latched function | - | Y |
| DI with counter input | - | Y (100 Hz) |
| Power on value | - | Y |
| Safe value | - | Y |
| Programmable slew-rate for AO module | - | Y |
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.
The support list of MCU (Main Control Unit) and I/O expansion unit are:
I-8K Series VS I-87K SeriesThere are two types of I/O modules, Parallel and Serial. The I-8K series modules are high-speed modules with parallel interface and the I-87K series are serial interface modules. Both they are supported on PAC (Programmable Automation Controller) units listed in the following table. |

I-8K Series VS I-87K SeriesThe high-speed I-8K series are parallel interface modules and I-87K series are serial interface modules. Both they are supported on PAC-base slave I/O unit. But only I-87K series modules are supported on expansion I/O units like I-87Kn, ET-87Pn, RU-87Pn and USB-87Pn series units. |
