The Omron S8VS-24024, also cataloged as the S8VS-24024 Switch Mode Power Supply, operates as a dedicated hardware component for direct AC-to-DC power conversion and regulated voltage delivery within PLC and industrial automation control cabinets. Accepting a wide rated input voltage range of 100 to 240 VAC, the unit converts primary mains power into a stabilized 24 VDC output with a 240 W power rating. It delivers high electrical conversion efficiency to drive field instruments and control hardware across industrial automation architectures.

Part Number Nomenclature & Options

• S8VS: Omron DIN-rail mount switch-mode power supply product family.
• 240: Power output rating designation (240 W maximum capacity).
• 24: Regulated output voltage specification (24 VDC nominal).

Operating Parameters

Bus Power Distribution & Automation System Integration

The regulated 24 VDC bus feeds field sensors, digital I/O expansion racks, and PLC backplanes linked via Profinet / EtherNet/IP deterministic networks. Maintaining ultra-stable output voltage under heavy line-load variations prevents data corruption during high backplane bus communication velocity operations. High I/O density scaling setups benefit from low ripple voltage, preserving signal accuracy and firmware flash compatibility across connected automation devices.

Mechanical Mounting & Cabling Guidelines

• DIN-Rail Mounting: Snap the supply vertically onto a standard 35 mm DIN rail, keeping top and bottom ventilation gaps clear for convective cooling.
• AC Input Connections: Connect 100 to 240 VAC supply lines to L and N screw terminals; wire the protective earth (PE) terminal directly to ground.
• DC Output Wiring: Connect 24 VDC load cables to output positive (+) and negative (-) terminals, ensuring proper gauge selection to minimize voltage drop.
• Thermal Ventilation: Maintain minimum 20 mm lateral clearance from adjacent heat-generating devices to maintain operation within -10 to 60 deg C limits.
• Noise Isolation: Keep 24 VDC output lines physically separated from high-voltage motor drives to prevent electromagnetic cross-talk.

Technical FAQ

• Does the S8VS-24024 support hot-swapping under live AC line power?

  Disconnect the main AC line power source before wiring or replacing the power supply unit to prevent hazardous electric shock.

• What happens if the output current exceeds the 240 W maximum load capacity?

  The unit enters overcurrent protection mode, automatically lowering output voltage to protect internal components and connected loads.

• Can multiple S8VS-24024 power supplies be connected in parallel for higher capacity?

  Parallel operation for increased output power is not supported unless external decoupling diodes are installed between output lines.

• How does input voltage fluctuation affect output stability?

  The switch-mode regulation maintains a constant 24 VDC output across the entire 100 to 240 VAC rated input voltage range.

• What grounding practice is recommended for the power supply chassis?

  Connect the protective earth (PE) terminal to the panel central ground rail using a short, low-impedance grounding strap.

• Does internal heat build-up limit output current capability?

  Operating above 50 deg C requires power derating; check ambient panel temperature to prevent thermal shutdown under full load.

• How does output ripple voltage affect sensitive analog input modules?

  Low output ripple prevents signal distortion on 24 VDC powered sensors and analog PLC input cards linked to field loops.

• Is external circuit protection required on the AC input side?

  Installing a dedicated miniature circuit breaker on the AC input line is recommended for short-circuit protection and isolation.
