Note: 1. The I/O delay time can be switched between normal speed and high speed.
2. The error processing method can be switched between HOLD and LOAD OFF.
3. C200H-CPU01/02/03/11 cannot be used.
Approved Standards
The "approved standards" column in the above table indicates
approval for (UL, CSA, cULus, cUL, NK, or Lloyds) or compliance
with (EC Directives) the relevant standard or directive as of the end
of April, 2001. Enquire separately for details on the conditions
required to meet these standards and directives.
EMC Directive
OMRON devices that comply with EC Directives also conform to the
related EMC standards so that they can be more easily built into oth-
er devices or the overall machine. The actual products have been
checked for conformity to EMC standards (see the following note).
Whether the products conform to the standards in the system used
by the customer, however, must be confirmed by the customer.
EMC-related performance of the OMRON devices that comply with
EC Directives will vary depending on the configuration wiring, and
other conditions of the equipment or control panel on which the
OMRON devices are installed. The customer must, therefore, per-
