Description

YOKOGAWA SPW481-53 Power Supply Module

The YOKOGAWA SPW481-53 is a high-reliability power supply module designed for industrial automation systems, delivering stable AC-to-DC power conversion for control equipment, data collectors, and field instruments. As part of Yokogawa’s OPREX measurement and automation portfolio, the SPW481-53 ensures consistent performance in harsh environments, making it ideal for critical applications in manufacturing, energy, and process control.

1. Product Description

The YOKOGAWA SPW481-53 is a standard power supply module (non-explosion-proof) engineered to provide regulated DC power for Yokogawa’s automation systems. It converts 100–120 V AC input (50/60 Hz) into a stable DC output, supporting devices such as PLCs, I/O modules, and field sensors. Key features include overload, overvoltage, and short-circuit protection, ensuring system safety. With a compact design (5.1 cm × 20.3 cm × 14.6 cm) and lightweight construction (0.9 kg), the SPW481-53 integrates seamlessly into industrial setups. Its wide operating temperature range (-20°C to 70°C) and compliance with ISA G3 environmental standards make it suitable for dusty or corrosive environments.

6. Selection Recommendations

  • Voltage Compatibility: Ensure input voltage matches local power supply (100–120 V AC).
  • Current Requirements: Verify output current capacity (7 A) meets device load demands.
  • Environment: Use in ISA G3-compliant environments (dusty, corrosive).
  • Redundancy: Pair with dual terminal blocks for fault-tolerant systems.

7. Precautions

  • Wiring: Separate power (PLC/I/O) and signal lines; use shielded twisted pairs for analog signals.
  • Grounding: Ensure proper grounding of the module and shielding layers to reduce noise.
  • Maintenance: Replace backup batteries (if applicable) every 3 years (30°C average temperature).
  • Installation: Follow Yokogawa’s guidelines for terminal block or MIL connector cabling.
