Description

YOKOGAWA PW702 Power Supply Module

1. Product Description

The YOKOGAWA PW702 is a high-reliability power supply module designed for industrial automation systems, particularly Yokogawa’s distributed control systems (DCS) and process control platforms. Engineered to deliver stable DC power, the PW702 ensures consistent operation of instruments, controllers, and field devices in harsh industrial environments. With a compact design and advanced protection features, this module supports critical applications such as manufacturing, energy production, and water treatment. Key specifications include a 220–240V AC input (50/60 Hz) and a regulated +5.1V DC output (29A), providing robust power for DCS racks and modular systems. The PW702 integrates seamlessly with Yokogawa’s Centum CS/VP and ProSafe-RS systems, offering overload protection (2.5kV surge immunity) and compliance with global standards (CE, UL). Its DIN rail mountable design and hot-swap capability simplify installation and maintenance, reducing downtime in mission-critical operations.

3. Advantages and Features

  • Stable Power Delivery: Regulated +5.1V DC output with low ripple (≤50mV) for sensitive DCS components.
  • Robust Protection: Multi-layer safeguards (overload, thermal, surge) prevent equipment damage.
  • Space-Saving Design: Compact chassis integration (26×8×28 cm) for dense control systems.
  • High Efficiency: 90%+ power conversion reduces energy consumption and heat generation.
  • Ecosystem Compatibility: Native support for Yokogawa DCS platforms (Centum CS/VP, ProSafe-RS), minimizing configuration time.
Case Study: A chemical plant reduced power-related downtime by 20% using the PW702’s redundant power configuration, ensuring continuous operation during maintenance.

4. Application Areas and Use Cases

  • Industries: Oil & gas, power generation, water treatment, manufacturing.
  • Scenarios: DCS/PLC power supply, field device energization, safety system backup.
  • Use Case: A power plant deployed 10 PW702 modules to power its Centum VP DCS racks, achieving 99.99% uptime over 5 years with zero voltage fluctuations.

5. Competitor Comparison

Compared to similar modules:

 

  • Voltage Stability: ±1% output regulation (vs. ±2% in alternatives) for precision applications.
  • Current Capacity: 29A output (vs. 15–25A in comparable models) supports high-density I/O systems.
  • Yokogawa Ecosystem Integration: Pre-engineered compatibility with Yokogawa’s chassis and diagnostics, reducing commissioning time by 15%.

6. Selection Recommendations

  • Voltage Requirements: Match output (5.1V DC) with system needs (e.g., Yokogawa I/O modules).
  • Current Load: Ensure 29A capacity meets total system power draw (add 20% margin for expansion).
  • Environment: Rated for -20°C to +60°C; suitable for indoor/outdoor installations with IP20 protection.
  • Redundancy: Pair with a second PW702 for N+1 redundancy in critical systems.

7. Precautions

  • Installation: Follow Yokogawa’s ESD guidelines; secure DIN rail mounting with torque ≤1.5 N·m.
  • Voltage Check: Verify input voltage (220–240V AC) before connection to avoid damage.
  • Ventilation: Ensure adequate airflow (≥0.5 m/s) for thermal dissipation in enclosed racks.
  • Maintenance: Inspect connectors annually; replace modules every 7–10 years (based on duty cycle).
