Description
The PS24-EX SA910S is a 24 V DC power supply module designed for ABB's S900 remote I/O system, including installation in hazardous areas classified Zone 1/2. It delivers reliable power with options for redundant configurations.
Applications
Oil refineries: Serving as the core power supply for remote I/O stations, directly installed at the production site.
Fine chemical plants: Providing stable power to transmitters and actuators in explosion-proof areas.
Offshore drilling platforms: Achieving highly reliable power supply in extreme and confined hazardous spaces.
Natural gas pressure regulating stations: Ensuring the continuous operation of automated monitoring systems.
Pharmaceutical manufacturing plants: Handling process control involving volatile solvents.
Maintenance Recommendations
Hot-swap Check: This module supports hot-swap, allowing replacement without interrupting the primary voltage.
Terminal Tightness: Regularly check the base wiring to prevent poor 24V output contact due to prolonged vibration.
Redundancy Verification: If a redundant configuration is used (equipped with a TU921S terminal unit), the standby unit's performance should be verified periodically through software simulation switching.
FAQ
Q: Can the PS24-EX SA910S and SA920S be used interchangeably?
A: No. The SA920S is a later upgrade, and ABB explicitly states that these two modules must not be mixed in redundant configurations.
Q: Does the PS24-EX SA910S power supply require a separate explosion-proof enclosure?
A: It is an intrinsically safe module designed for Zone 1/2 and can be directly installed in the corresponding field cabinet.
Q: Will the PS24-EX SA910S power supply burn out if the output is short-circuited?
A: No. The module has short-circuit protection and will enter automatic protection mode when a short circuit is detected.
Q: Will the PS24-EX SA910S automatically recover after a power outage and restart?
A: Yes. Once the input AC voltage recovers to above 85V, the module will automatically start and output a stable 24V DC power.
Q: Do I need to reconfigure the software address when replacing the PS24-EX SA910S module?
A: No. It is a purely physical power supply module; replacing it with the same model requires no logic configuration in the host computer software.
