Parallel Bus (I-8K Series) VS Serial Bus (I-87K Series) I/O Modules

There are two types of I/O communication bus, parallel bus and serial bus. The parallel bus type I/O modules (high profile I-8K series) are high speed ones used only in the PACs including XPAC, WinPAC, iPAC, ViewPAC, etc. And the serial bus type I/O modules (high profile I-87K series) are low speed ones used in both PACs including XPAC, WinPAC, iPAC, ViewPAC, etc., and I/O expansion units including RU87Pn, ET-87Pn, USB-87Pn, etc.

A Comparison Between I-8KW Series and I-87KW Series

Models	I-8K Series	I-87KRW Series	I-87K Series
Communication Interface	Parallel bus		Serial bus
Protocol	-		DCON
DI with latched function	-		Yes
DI with counter input	-		Yes (100 Hz)
Power on value	-	Yes	Yes
Safe value	-	Yes	Yes
Programmable slew-rate for AO module	-		Yes

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.

I/O Modules for Supported PAC/ViewPAC

There 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/O Modules for Supported Remote I/O Expansion Units

The 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.
