ABB AO920S DCS I/O module (3KDE175531L9200)

AO920S Analog output.

The remote S900 I/O system can be installed in non-hazardous areas or directly in Zone 1 or Zone 2 hazardous area depending on the selected system variant. S900 I/O communicates with the control system level using PROFIBUS DP standard. The I/O system can be installed directly in the field, therefore the costs for mashalling and wiring are reduced. The system is sturdy, error-tolerant and easy to service. Integrated disconnection mechanisms allow replacement during operation, meaning that there is no need to interrupt the primary voltage in order to exchange the power supply units. S900 I/O type S. For installation in hazardous area Zone 1. For connecting intrinsically safe field devices installed in Zone 2 or Zone 1 or Zone 0. AO920S Analog Output (AO4I-Ex), output signal 0/4...20 mA for actuators. - ATEX Certification for installation in Zone 1 - Redundancy (Power and Communication) - Hot Configuration in Run - Hot Swap functionality - Extended Diagnostic - Excellent configuration and diagnostics via FDT/DTM - G3-coating for all components - Simplified maintenance with auto-diagnostics - Output signal 0/4...20 mA for actuators - Short and break detection - Electrical isolation between output / bus and output / power - Electrical isolation channel to channel - 4 channels
