Product Describe:
Siemens 405-4DAC-1 is a four-channel analog output module for the SIMATIC TI 405 platform. It supports maintenance of the installed control path when the complete identity and connected interfaces are matched.
Siemens 405-4DAC-1 performs the four-channel analog output module function within the SIMATIC TI 405 platform while retaining the interfaces assigned to its installed position.
Provides the four-channel analog output module function.
Integrates with the SIMATIC TI 405 platform.
Retains the assigned signal or communication path.
Uses the complete 405-4DAC-1 identity for replacement control.
The four-channel analog output module should remain matched to its installed terminals, configuration and receiving system. Verify the complete path after replacement.
Important Notice: Match Siemens 405-4DAC-1 to the installed position, terminals and controlled configuration. Verify the complete signal or communication path before release.
The first PDF covers the product function and technical data. The second covers connection checks, commissioning and release steps.
Installed-base maintenance
Restore the assigned four-channel analog output module position without changing the surrounding system design.
Loop and channel service
Retain terminal assignments, scaling and channel ownership during controlled replacement.
Fault isolation
Separate module, field wiring and configuration causes during troubleshooting.
Commissioning
Prove the complete signal path before returning the process to service.
