Features:
- Bridge Between Control System and Intrinsically Safe Field Actuators in Hazardous Areas
- Integrates 0/4...20 mA Analog Output Capability with Zone 1 Installation and Channel-to-Channel Isolation
- Functions as Part of the S900 I/O System Communicating via PROFIBUS DP Standard
The AO920S 3KDE175531L9200 serves as the Analog Output Module (AO4I-Ex) within the S900 I/O remote station, delivering reliable 0/4...20 mA signals to actuators connected through intrinsically safe field circuits. It continuously generates precise current output for up to four channels and distributes these signals through isolated output circuitry to support steady state operation of control valves, drives, and other final control elements in Zone 0, Zone 1, or Zone 2 hazardous areas. Seamless signal integrity is standard with the AO920S 3KDE175531L9200, and the module's built-in short and break detection ensures immediate fault identification in the event of a field wiring anomaly.
The AO920S 3KDE175531L9200 provides essential analog output functions for the S900 I/O system and is a critical component of the control path, directly affecting the proper, normal operation of field actuators in process automation environments. One AO920S 3KDE175531L9200 module occupies a single slot within the S900 I/O station and delivers four independent output channels.
For enhanced system availability, the S900 I/O platform supports redundancy at both the power and communication levels. In addition to standard single-module operation, the S900 system architecture allows hot-swappable replacement of the AO920S 3KDE175531L9200 without interrupting primary voltage. The S900 I/O station executes module monitoring using integrated auto-diagnostics specified in the AO920S design.
The AO920S 3KDE175531L9200 ABB Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
