Features:
- Exact identity is PW302 with style S4; do not substitute PW301, PW304 or another style by appearance.
- The public exact-unit marking identifies 220–240 VAC input and multiple +5.1 V and +12 V output rails.
- Yokogawa lists PW302 in its official obsolete DCS-product reference, so the installed cabinet record controls replacement.
Yokogawa PW302 S4 is a rack power supply module identified for a legacy CENTUM control-system installation. The exact-unit public nameplate reference shows a 220–240 VAC, 50/60 Hz, 3.0 A input and DC rails of +5.1 V, +5.1 V standby and +12 V with 142 W maximum output. Yokogawa's official obsolete-product list includes PW302, so replacement must reproduce the complete model and style marking, input class, connector and rack position. The installed load, redundant arrangement, battery or standby circuit and receiving cabinet documentation remain the governing selection evidence.
Use only after matching PW302, style S4, the input marking, output rails, connector, rack position and installed cabinet configuration. Do not substitute a related PW30x supply by family resemblance. The public exact-unit marking identifies a 220–240 VAC, 50/60 Hz, 3.0 A supply with +5.1 V (15 A and 4 A), +5.1 V standby (2 A), +12 V (5 A) and 142 W maximum output. Confirm these values on the supplied nameplate before installation. PW302 is included in Yokogawa's official obsolete-product reference. Match style S4, rack position, connector, cabinet source, protected load, redundant arrangement and any standby or battery circuit to the installed engineering record.
The Yokogawa PW302 S4 Rack Power Supply Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Confirm the complete catalog identity, hardware revision, receiving-system configuration and required document revision before replacement.
Confirm the S4 nameplate, 220–240 VAC source, 50/60 Hz frequency, branch protection, connector and grounding before energizing.
Check every +5.1 V, standby and +12 V rail against the installed rack load; do not infer interchangeability from the PW30x family.
Record slot position, mating connector, load sharing or redundant arrangement, battery circuit and cabinet wiring before exchange.
