Omron S8AS2-48024-08SN Smart Power Supply

The Omron S8AS2-48024-08SN Smart Power Supply is a 480 W industrial power supply that distributes 24 VDC power through eight electronically protected branches. It is designed for automation panels requiring higher power capacity, standardised protection settings, and circuit-level operating information. OEMs, engineering companies, panel builders, and maintenance teams can contact Emaconn for current pricing, product availability, lead-time information, and quotation support.

Omron S8AS2-48024-08SN Eight-Branch Power Distribution for Industrial Equipment

The S8AS2-48024-08SN supplies multiple control circuits from a single power source while keeping the loads separated into eight branches. This arrangement can simplify panel architecture and provide technicians with a clearer view of how power is distributed throughout the machine.

The unit accepts an input voltage range of 85 to 264 VAC at 50 or 60 Hz. It delivers a nominal 24 VDC output with a total rated output current of 20 A. The output voltage can be adjusted from 24 to 28 V through the voltage adjustment control.

Each output branch has a maximum cutoff current of 3.8 A. The total connected load must remain within the 20 A rating, and every individual circuit must be suitable for the fixed branch protection characteristics.

Standardised Fixed Protection Settings

The SN suffix identifies a configuration with predefined protection and sequencing values. Abnormal-current tripping is fixed at 3.8 A per branch, while abnormal-voltage tripping is fixed at 32.0 V. The undervoltage alarm threshold is set to 20.0 V.

Fixed settings can be useful for machine platforms where identical electrical behaviour is required across several panels or production units. They reduce commissioning decisions and help prevent settings from being changed unintentionally after installation.

This configuration is not automatically suitable for every load. Engineers should calculate normal current, startup current, temporary overload behaviour, and cable capacity before ordering. Applications requiring adjustable branch thresholds should instead be evaluated for the S8AS2-48024-08S variant.

Defined Startup Sequence Across Eight Outputs

The branch outputs use a fixed sequential startup arrangement. Branch 1 starts without a programmed delay, followed by the remaining branches at intervals of 0.4 seconds. Branch 8 is activated after 2.8 seconds.

This staged startup can reduce the effect of energising all connected circuits simultaneously. It may also support machines that require control devices to start in a consistent order. The shutdown sequence is fixed at 0.0 seconds for all branches.

External tripping is enabled for every branch and cannot be disabled on the SN model. This characteristic must be considered when designing the control logic and wiring the external tripping input.

Diagnostic Information at the Control Panel

The integrated display gives maintenance teams access to output voltage, individual branch current, peak branch current, total current, internal temperature, accumulated running time, and maintenance forecast information. These functions make the power supply more than a basic AC-to-DC converter.

If a branch is interrupted because of an abnormal condition, the available information can help technicians identify the affected circuit. Comparing the current of each branch also supports load analysis during commissioning and scheduled maintenance.

The maintenance forecast monitor provides information that can be incorporated into preventive maintenance planning. It should be used together with physical inspection, terminal checks, ventilation control, and an evaluation of actual operating conditions.

Omron S8AS2-48024-08SN Where Can This Model Be Applied?

The Omron S8AS2-48024-08SN may be used in control cabinets for packaging machinery, automated production lines, material-handling equipment, assembly systems, inspection machines, logistics installations, and process automation.

Its eight branches can distribute power to PLC modules, sensors, interface relays, operator terminals, industrial communication equipment, and other compatible 24 VDC devices. Organising these loads by machine function helps maintenance teams identify and isolate electrical problems more efficiently.

For replacement applications, the purchasing decision should not be based only on the 480 W and 24 VDC ratings. The number of branches, terminal configuration, physical dimensions, startup sequence, external tripping behaviour, and SN suffix must also be verified.

Ordering Checklist for Engineering Teams

Confirm the 85 to 264 VAC input range.
Calculate the total continuous 24 VDC load.
Keep the combined output current within 20 A.
Check the current demand of every branch.
Verify compatibility with the fixed 3.8 A cutoff value.
Review the fixed startup sequence.
Confirm the required external tripping behaviour.
Check DIN rail and enclosure space.
Review environmental and certification requirements.
Verify the complete S8AS2-48024-08SN part number.

These details are especially important when preparing a replacement order. An apparently similar S8AS2 model may offer adjustable settings or a different number of output branches. Emaconn can assist with model comparison when the existing specification or machine documentation is available.

Installation and Maintenance Planning

The power supply is intended for DIN rail mounting inside an industrial control enclosure. Its IP20 protective structure requires the panel to provide the necessary protection against environmental exposure and contact with live parts.

Installation should be completed according to the official Omron instructions. Relevant checks include mounting orientation, ventilation space, protective earthing, conductor size, terminal tightening, branch identification, and correct input and output wiring.

The model does not support series or parallel connection. If greater power capacity is required, engineers should revise the supply architecture or select a suitable higher-capacity solution. During commissioning, voltage, polarity, branch current, total current, startup order, and external tripping operation should be tested.

Procurement and Model Verification Through Emaconn

Emaconn provides sourcing support for the S8AS2-48024-08SN in new automation projects, replacement programmes, planned maintenance, and machine-building requirements. Customers can request a quotation by providing the full part number, quantity, delivery location, and required schedule.

Commercial support may include current price information, stock-status confirmation, estimated lead time, project-based supply planning, and alternative-product research. Technical product selection assistance is also available when buyers need to compare the fixed SN version with the adjustable S variant.

For related power supplies and automation components, review the Omron product range supplied by Emaconn. Submit the application data before ordering when electrical or mechanical compatibility requires confirmation.
