ABB PU515 3BSE013063R1 Power Supply Module

Description

1. Core Overview & Positioning

2. Key Features & Functions

• Dual-Isolated Outputs:​ Typically provides two completely isolated DC output voltages:
  • Logic/System Supply (+5V DC):​ Powers the internal electronics and communication circuits of the S800 I/O modules.
  • Field/External Supply (+24V DC):​ Provides a separate, isolated 24V source for powering the field side of the I/O modules, which in turn powers connected sensors (for DI/AI) and actuators (for DO). This isolation protects the system from field-side electrical noise and faults.
• Wide Input Voltage Range:​ Designed to accept a broad range of input voltages, making it suitable for various global standards. Common input specifications include 24V DC, 115/230V AC, or a universal AC/DC input (e.g., 24-240V AC/DC).
• Overload and Short-Circuit Protection:​ Includes electronic protection on its outputs. In case of an overload or short circuit on the field side, the supply will current-limit or shut down to prevent damage, and then automatically restart when the fault is cleared.
• Status Indication:​ Features LED indicators to show the status of the input power and the health of the +5V and +24V outputs (e.g., green for OK, red/yellow for fault).
• DIN-Rail Mountable:​ Compact design for easy installation on standard DIN rails within control panels.
• Hot-Swappable (in some systems):​ In redundant power configurations, it can be designed to be replaced without shutting down the entire I/O station.

3. Model Number & Order Code Analysis

• Input Voltage:​ Likely a wide-range AC/DC input​ (e.g., 24-240V AC/DC) to provide maximum flexibility.
• Outputs:
  • System Voltage:​ +5V DC at a specified current (e.g., 3A).
  • Field Voltage:​ +24V DC at a specified current (e.g., 3A).
• Output Power:​ Total power rating typically in the range of 50-100 Watts.
• Isolation:​ 1500V AC or higher between input, outputs, and chassis for safety and noise immunity.
• Protections:​ Overvoltage, overcurrent, and short-circuit protection on outputs; over-temperature shutdown.
• Efficiency:​ High efficiency (>85%) to minimize heat generation.

4. System Integration & Architecture

• Role in S800 I/O Station:​ The PU515 is the central power hub​ for a local cluster of S/O modules. It is typically mounted on a DIN rail alongside the I/O modules and a communication interface (like a CI867 PROFIBUS module).
• Typical Wiring:
  1. Input:​ Connected to the plant’s unregulated 24V DC bus or directly to an AC source via a line filter/fuse.
  2. System Output (+5V):​ Connected to the backplane or bus of the S800 station to power the internal logic of all I/O cards.
  3. Field Output (+24V):​ Distributed via a terminal block to the «L+» terminals of the individual I/O modules to power connected sensors and actuators.
• Redundant Configurations:​ For high-availability systems, two PU515 modules can be configured in parallel (using optional diode modules) to provide N+1 redundancy. If one fails, the other seamlessly takes over the entire load.

5. Typical Applications

• Process Automation (DCS):​ Distributed I/O stations in ABB 800xA or Legacy Advant systems.
• Factory Automation:​ Machine control panels using S800 I/O connected to a PLC (e.g., via PROFIBUS with a CI867 module).
• Any application requiring reliable, isolated power for a bank of ABB S800 analog and digital I/O modules.
