Description

Product Introduction

Reliance Electric 45C922 is a 115/230 VAC input power supply module for the Shark XL series PLC racks. It converts AC line voltage into regulated DC power for the backplane and I/O modules, providing stable, isolated power distribution in industrial control systems. Compact DIN‑rail mounting, built‑in overvoltage/overcurrent protection, and LED status indicators ensure high reliability and easy diagnostics in factory environments.

Model Interpretation

  • 45C = Family code for Reliance Electric Shark XL / AutoMax series system modules.

  • 922 = Power supply module; “9” denotes system power, “22” denotes 115/230 VAC dual‑range input type.

  • No suffix indicates standard revision; functionally fixed within the Shark XL line.

Technical Parameters

  • Input voltage: Jumper‑selectable 115 VAC or 230 VAC (100–240 VAC range).

  • Input frequency: 50/60 Hz.

  • Output: Regulated DC for backplane; typical 24 VDC / 0.25 A or system‑specific DC rails.

  • Max output current: System‑rated up to 16 A (backplane total).

  • Protection: Overvoltage, overcurrent, short‑circuit, thermal shutdown.

  • Isolation: Input‑to‑output galvanic isolation.

  • Indicators: Power OK LED, fault LED (overvoltage/overcurrent/thermal).

  • Operating temperature: ‑20 °C to +60 °C.

  • Storage temperature: ‑40 °C to +85 °C.

  • Humidity: 0–95% RH, non‑condensing.

  • Protection class: IP20 (cabinet mounting).

  • Mounting: Shark XL / 45C‑series DIN rail.

  • Certification: UL/CUL, CE, CSA, FCC.

  • Lifespan: >50,000 hours under rated conditions.

Interface and Communication Configuration

  • Backplane connection: Plug‑in to Shark XL rack backplane for DC power distribution.

  • AC input: Screw terminals for line, neutral, ground.

  • Communication: No external communication ports; power‑only module.

  • Compatibility: Shark XL series racks; works with 45C‑series I/O modules.

Core Functions

  • Converts 115/230 VAC line power into stable DC for the PLC backplane and I/O modules.

  • Provides galvanic isolation between AC line and control circuits to suppress noise and enhance safety.

  • Built‑in overvoltage, overcurrent, short‑circuit, and thermal protection safeguards the system.

  • LED status enables real‑time monitoring of power health and fault conditions.

  • Supports hot‑swap replacement (with system power removed) for minimal downtime.

Application Scenarios

  • Industrial automation: Powering Shark XL PLC racks and 45C‑series I/O modules in manufacturing, process control, and material handling.

  • Panel building: Standard power supply for OEM control panels requiring 115/230 VAC input and isolated DC distribution.

  • Harsh environments: Suitable for factory floors with wide temperature fluctuations and electrical noise.

Operation and Maintenance Instructions

  • Install on a Shark XL DIN rail and ensure full backplane engagement before wiring.

  • Set the input voltage jumper to 115 VAC or 230 VAC per local line voltage.

  • Torque AC input terminals to manufacturer specs; verify proper grounding.

  • During operation, monitor LEDs: Power OK ON, fault LED OFF for normal status.

  • Keep the module clean and well‑ventilated to prevent overheating.

  • Disconnect AC power before removal, inspection, or replacement.

  • Do not disassemble internal components; replace the entire module if a permanent fault occurs.

  • The unit is discontinued by Reliance Electric; use surplus or refurbished units for replacement.
