B&R X20PS9400 – 24 VDC Power Supply Module for the X20 Automation System

The B&R X20PS9400 is a dedicated 24 VDC power supply module for the X20 modular control platform. It feeds the internal X2X backplane and, in many cases, also provides a convenient 24 V feed-through for field devices, so you can keep wiring tidy and service simple. From my experience, this unit is a common pick when you need a slim, cabinet-friendly supply point that matches the mechanics and installation logic of the X20 series.

Typical use cases include packaging and converting lines, compact machine tools, and distributed I/O nodes on material handling systems—anywhere you want a clean, reliable 24 V backbone for controllers and I/O without adding a separate third-party PSU footprint. One thing I appreciate is how quickly technicians can swap it during maintenance because it follows the familiar X20 terminal base format.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: typically 1 week if in stock; no more than one month at the latest
• Payment terms: 50% advance payment; full payment prior to delivery
• Express delivery options: FedEx, UPS, DHL

Key Features

• Tailored for B&R X20 platform – Mechanical fit and wiring concept align with X20 terminal bases, so installation stays clean and consistent across the rack.
• 24 VDC system supply – Distributes 24 V to the X2X backplane for controllers and I/O; you might notice fewer separate power rails inside the cabinet.
• Slim cabinet footprint – The narrow X20 form factor frees DIN-rail space, which is helpful in compact machine panels.
• Practical field-power pass-through – In many cases there’s a convenient 24 V feed for sensors/actuators, reducing external distribution blocks.
• Service-friendly indicators – Status indication helps maintenance teams confirm DC OK or detect a supply fault at a glance.
• Robust in typical industrial environments – Designed for standard machine temperatures and vibration levels found on the shop floor.

Technical Specifications

Related or Supporting Products

• B&R X20PS2100 – 24 VDC power module for smaller I/O counts; a good fit when total load is limited.
• B&R X20PS3300 – higher-capability supply module for larger nodes or more demanding field loads.
• B&R X20BM / X20TB series – terminal bases and bus modules that the X20 electronics snap onto; choose the base to match your wiring style.

If you’re swapping from another X20 power module, it seems to be best practice to check total 24 V consumption (controller + I/O + field devices) and leave 20–30% headroom. A packaging OEM we support typically pairs the X20PS9400 with compact CPU modules and 6–12 I/O slices per node without space headaches.

Installation & Maintenance

• Cabinet environment – Keep within 0–55 °C, non‑condensing humidity; allow airflow and avoid heat hotspots near drives.
• Mounting – Install on DIN rail with the correct X20 terminal base; place the power module at the left of the X20 segment so it feeds the backplane properly.
• Wiring – Use a SELV/PELV 24 VDC source; properly fuse the 24 V feed; use ferrules where possible; ensure a solid protective earth bonding to the panel.
• Separation – Route 24 V and signal wiring away from high‑noise cables (motor leads, contactors) to reduce interference.
• Checks – Verify DC OK indication during commissioning; periodically re‑torque terminals and clean dust; there’s no firmware to update on the power module itself.

Quality & Certifications

• CE marked; RoHS compliant
• Typically UL / cULus recognized for industrial control equipment
• Manufactured under ISO 9001 quality systems
• Warranty: 365 days (manufacturer warranty is commonly 12 months; our service coverage aligns with that)
