Specifications

Description

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 the PROFIBUS DP standard. The I/O system can be installed directly in the field, therefore the costs for marshalling 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, Zone 1 or Zone 0.

AO920S 3KDE175531L9200 Analog Output (AO4I-Ex), output signal 0/4...20 mA for actuators.

Applications

Oil refineries: Control valves for crude oil distillation or hydrocracking units in Zone 1/2 hazardous environments.

Offshore oil platforms: Direct-drive explosion-proof actuators in confined and flammable offshore facilities.

Chemical plants: Suitable for pressure control of reactors and flow regulation of materials handling volatile chemicals.

Natural gas booster stations: Emergency shut-off valves for the safe control of gas pipelines in areas with a risk of natural gas leaks.

Fine pharmaceutical plants: Control systems for centrifuges or drying equipment handling flammable solvents.

Features and benefits

ATEX Certification for installation in Zone 1

Redundancy (Power and Communication)

Hot Configuration in Run

Hot Swap functionallity

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

Maintenance

Hazardous Zone Hot-Swapping: Supports live module replacement in Zone 1 hazardous areas without a hot work permit (must comply with on-site safety procedures).

Safe Position Setting: Before replacement, confirm the failsafe value of this channel via the control system (e.g., 800xA or Freelance) to prevent accidental valve actuation when removing the module.

Base Compatibility: Must be installed on an S900 Type S (blue) base; never use with non-intrinsically safe components.

FAQ

Q: What is the AO920S 3KDE175531L9200?
A: It is a Analog Output Module.

Q: Does the AO920S 3KDE175531L9200 support HART communication?
A: No. AO920S 3KDE175531L9200 only supports pure 4–20 mA analog signals. If HART diagnostics or communication are required for smart valve positioners, AO930S should be selected instead.

Q: What is the difference between AO920S and AO920N?
A: AO920S is intrinsically safe, designed for Zone 1, and can connect to intrinsically safe devices in Zone 0.
AO920N is intended for non-explosion-proof safety zones and does not provide intrinsic safety or explosion-proof protection.
