Siemens SIMATIC S7-200 System Manual page 407

Maritime Approvals
The S7-200 products are periodically
submitted for special agency approvals
related to specific markets and applications.
This table identifies the agency and
certificate number that the S7-200 products
have been approved for. Most S7-200
products in this manual have been
approved for these special agency
approvals. Consult your local Siemens
representative if you need additional
information related to the latest listing of
exact approvals by part number.
Relay Electrical Service Life
The typical performance data supplied by relay vendors is shown in Figure A-1. Actual
performance may vary depending upon your specific application.
An external protection circuit that is adapted to the load will enhance the service life of the
contacts.

Technical Specifications
All S7-200 CPUs and expansion modules conform to the technical specifications listed in
Table A-1.
Notice
When a mechanical contact turns on output power to the S7-200 CPU, or any digital expansion
module, it sends a "1" signal to the digital outputs for approximately 50 microseconds. You must
plan for this, especially if you are using devices which respond to short duration pulses.
