Wiring A Fail-Safe I/O Module - Siemens SIMATIC ET 200eco Manual

Power Supply Requirements in Compliance with NAMUR Recommendations
Note
You must use only power packs or power supplies (230 VAC --> 24 VDC) with a
power failure ride-through of at least 20 ms to comply with NAMUR
recommendation NE 21, IEC 61131-2, and EN 298. The following power supply
board components are available, for example:
S7-400:
6ES7 407-0KA01-0AA0 for 10 A
•
6ES7 407-0KR00-0AA0 for 10 A
•
S7-300:
6ES7 307-1BA00-0AA0 for 2 A
•
6ES7 307-1EA00-0AA0 for 5 A
•
6ES7 307-1KA00-0AA0 for 10 A
•
These requirements also apply, of course, to power packs and power supplies
that do not have an S7-300 or S7-400 configuration.

Wiring a Fail-Safe I/O Module

Same Wiring Procedure as for ET 200eco
The fail-safe ET 200eco I/O module belongs to the I/O module spectrum of
ET 200eco.It is wired in the same way as all standard ET 200eco I/O modules.
For more information about wiring I/O modules, refer to the ET 200eco Distributed
I/O Station manual.
Warning
!
When assigning signals of the fail-safe I/O module, remember that signals should
only be routed within a cable or a nonmetallic sheathed cable if:
A short circuit in the signals does not conceal a serious safety risk
•
Signals are supplied by different sensor supplies of this fail-safe I/O module
