Go to I-8K Series Go to I-87K Series I-8K Series VS I-87K Series
There 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 Series
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.PAC Description I-8K Series I-87K Series High Profile Low Profile High Profile Low Profile XPAC WES/CE6 OS Y… - Y… - WinPAC CE5 OS Y… - Y… - LinPAC Linux OS Y… - Y… - ViewPAC PAC with Display Y(Note) - Y(Note) - iPAC MiniOS7 OS Y - Y - iPPC-6731-WES7 WES PAC with 15" Touch Panel Y - Y - MP-8000 Motion PAC Y… - - - I-8000 MiniOS7 OS Y Y Y Y I-8K Series VS I-87K Series
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.Slave I/O unit Protocol Interface I-8K Series I-87K Series Ethernet RS-485 High Profile Low Profile High Profile Low Profile I-8x10 DCON -
