Siemens 6ES5316-8FA12 extends an S5-90U/95U/F, S5-100U, ET 100U or ET 200U arrangement through an IM 316F connection with increased EMC resistance.
Connects up to three expansion rows through the IM 316F interface.
Supports the listed S5-90U/95U/F, S5-100U, ET 100U and ET 200U contexts.
The F execution provides increased EMC resistance.
Connector options cover 0.5 m through 10 m.
The retained expansion-row map, cable order number and receiving host must agree before replacement; the IM 316 interface-module table defines the matching connector and current limits.
Important Notice: confirm the IM 316F identity, the host family and every expansion-row cable before isolation.
The first document is an unchanged exact-model Siemens manual excerpt; the second is a separate Apter Power field guide for readiness, installation, verification and handover.
SIMATIC S5 expansion
Connects retained expansion rows to a supported S5 controller arrangement.
Distributed I/O extension
Supports an ET 100U or ET 200U expansion context.
EMC-sensitive cabinet service
Maintains the increased-EMC-resistance IM 316F execution.
Legacy row replacement
Preserves the accepted cable lengths, row order and module assignment.
Apply these checks to the exact Siemens 6ES5316-8FA12 installation before isolation, replacement or release.
1
Confirm the complete Siemens 6ES5316-8FA12 and IM 316F markings.
2
Record the controller family, interface position and each expansion row.
3
Label every connector and verify its cable order number.
4
Place the PLC and all connected rows in the approved maintenance state.
5
Check the one-ampere expansion-unit limit and retained grounding arrangement.
6
Restore the recorded row order, cable routing and mechanical retention.
7
Review controller and remote-I/O diagnostics after energization.
8
Verify communication with every configured expansion row before release.
Technical notes
Keep the IM 316F interface position, expansion-row order, connector order numbers, current loading and grounding arrangement together. After replacement, prove communication with every configured row.
