This is a robust, high-performance power supply that ensures the continuous and accurate operation of your Fieldbus Modules (FBMs), Field Control Processors (FCPs), and Fieldbus Communication Modules (FCMs) by providing them with conditioned 24 VDC power.

Core Features and Reliability: Powering the Heart of Your DCS

What distinguishes the FOXBORO FPS400-24 P0922YU as a top-tier industrial power supply?

1. High Power Output (400W @ 24VDC): With a 400 Watt output capability, this power supply can support a significant load of FBMs, FCPs, and FCMs on multiple baseplates within a subsystem. This allows for flexible system sizing and future expansion.

2. Wide-Range AC/DC Input (P0922YU specific): The P0922YU model is highly versatile, accepting a wide range of input voltages from 85 to 265 VAC (47-63 Hz) or 108 to 145 VDC (nominal 125 VDC). This “universal” input capability makes it suitable for deployment in facilities worldwide, accommodating different regional power standards without requiring specific ordering. (Note: There is also a P0922YC variant that takes a 24 VDC input).

3. Exceptional Efficiency: These power supplies boast very high efficiency, with the P0922YU achieving up to 95% efficiency. High efficiency translates directly into less wasted energy (less heat generated), which improves reliability, extends the lifespan of the unit, and contributes to lower operating costs due to reduced power consumption and less demand on cooling systems.

4. Power Factor Correction (PFC): For AC input models like the P0922YU, advanced circuitry provides active sinusoidal current profile for near-unity controlled power factor. This means the power supply draws current more efficiently from the AC line, reducing harmonic distortion and improving overall power quality for the plant’s electrical system.

5. Robust Protection Features:

   • Current Limiting: The power supply operates as a constant voltage source. If the load current attempts to exceed approximately 110% of its maximum rating, the output voltage will decrease to limit the current, protecting both the power supply and the connected devices from overcurrent conditions.
   • Overvoltage Protection: It has factory-set overvoltage shutdown circuitry (typically at 28.0 VDC for FBM/FCM/FCP applications). If the output voltage exceeds this limit, the power supply automatically shuts down to protect sensitive control system components.
   • Transformer Isolated Output: The 24 VDC output is transformer isolated, providing a critical layer of electrical isolation between the input power and the control system, enhancing safety and noise immunity.

6. Sealed and Gasketed Design (Convection Cooling): The robust construction features a sealed and gasketed housing. This design is highly beneficial for industrial environments because it eliminates the need for cooling fans, which are common failure points in traditional power supplies. The sealed nature also protects internal components from airborne contaminants, dust, moisture, and corrosive atmospheres (such as those containing hydrogen sulfides or chlorine), significantly reducing maintenance requirements and extending operational life. This design contributes to its G3 rating for harsh environments (per ISA Standard S71.04).

7. Hazardous Location Certifications: The FPS400-24 is agency certified for use in Class I, Division 2, and Zone 2 hazardous locations (e.g., UL and UL-C listed, CENELEC certified). This makes it suitable for deployment in areas where flammable gases or vapors may occasionally be present, a common requirement in industries like oil & gas and chemical processing.

8. Status Alarm Output: It includes a Form C relay output that activates to indicate the absence of the 24 VDC output (e.g., in case of a fault or shutdown). This allows operators or higher-level control systems to be immediately alerted to a power supply issue, enabling prompt troubleshooting and recovery. Visual LED indicators also provide local status.

9. DIN-Rail Mounting: Designed for easy and secure mounting on standard DIN rails, simplifying installation and enabling a clean, organized layout within control cabinets. The mounting bracket can be rotated for horizontal or vertical DIN rail mounting, or even removed for direct wall mounting.

While the FPS400-24 provides power to the 200 Series baseplates, it’s generally recommended that the same power supply not be used to power both the baseplates and external field devices to maintain system integrity.

Related Products:

The FOXBORO FPS400-24 P0922YU works in close conjunction with:

• Foxboro DIN Rail Mounted Baseplates: These are the physical carriers (e.g., P0922RC, RH924YF) that the FBMs, FCPs, and FCMs plug into. The FPS400-24 supplies power directly to these baseplates.
• Foxboro Fieldbus Modules (FBMs): All 200 Series FBMs (e.g., FBM201, FBM202, FBM205, FBM211, FBM242) rely on the 24 VDC power supplied by the FPS400-24.
• Foxboro Field Control Processors (FCPs): Controllers like FCP270 and FCP280, which are typically mounted on dedicated baseplates, receive their operating power from the FPS400-24.
• Foxboro Fieldbus Communication Modules (FCMs): Modules like FCM10E or FCM10EF, also mounted on baseplates, are powered by the FPS400-24 to facilitate communication across the Fieldbus.
• Redundant Power Supply Configurations: Often, two FPS400-24 units (or a combination of P0922YU and P0922YC if DC input is also used) are used in a redundant setup, with their outputs connected to redundant power input terminals on the baseplates to provide fault tolerance.
• Power Distribution Cables and Terminal Blocks: Specific cables are typically used to connect the FPS400-24 to the baseplates, ensuring proper power distribution.
