Features - Hitachi HSC-2100 Hardware Manual

1 GENERAL INFORMATION

1.1 Features

The HSC-2100 I/O modules covered in this manual are I/O modules provided as replacement
modules to replace I/O modules used in S10/2α and S10/4α controllers. These replacement
modules are functionally compatible with HSC-2000 I/O modules (in terms of the product
specifications contained in their hardware manuals). However, there are differences in
performance level between the two groups of I/O modules, as you can see from the product
specifications. These differences are due to the fact that the HSC-2100 group of I/O modules
has updated internal circuits and components used in them. Consequently, the two groups of I/O
modules are not fully compatible with each other. For this reason, if an existing HSC-2000 I/O
module is replaced with a latest HSC-2100 I/O module, influence from noise may pose a problem
on the newly installed HSC-2100 I/O module, depending upon the installation environment in
which the replaced HSC-2000 I/O module was previously used. In this case, please check the
installation environment for noise source and take a measure to reduce the noise level.
The HSC-2100 I/O modules have the following features:
Making it possible to replace I/O modules in S10/2α and S10/4α controllers without the need
to alter the existing wiring on the terminal blocks
Compatible with the I/O voltage and current specifications of I/O modules used in S10/2α and
S10/4α controllers, thus eliminating the need to re-design those programmable controllers
Making it unnecessary to add changes to the existing software at the time of replacement,
except when the programmable controller is S10/4α -- in the case of S10/4α controllers, their
existing ladder programs need conversion at the replacement.
Installable in HSC-2100 I/O units together with I/O modules of an S10/2α or S10/4α
controller, or installable in I/O units of the S10/2α or S10/4α controller
