Product Description

The PS-502-A1 is a high-reliability power conversion module that transforms an unstable 24 V DC field voltage into a galvanically isolated and regulated 24 V DC output. It is built in a single Euro-format (6TE) and is engineered for mission-critical industrial safety applications where electrical isolation and stable voltage are paramount.

Product Parameters

Key Advantages

• Redundancy Support: Modules can be connected in parallel for increased current capacity or N+1 redundancy. It features a built-in serial diode for safe load sharing.

• Galvanic Isolation: Protects sensitive logic circuits from field-side electrical noise and surges.

• Comprehensive Protection: Equipped with overvoltage (crowbar) and overcurrent (fold-back) protection to prevent damage to downstream modules.

• Diagnostic Indicators: Includes two red LEDs on the front panel to indicate the status of the input voltage and the regulated output voltage.

• Fine Tuning: A front-accessible trimmer allows for precise adjustment of the output voltage to compensate for line drops.

Precautions & Maintenance

• Total Load Limit: The combined current from both the regulated (24V) and unregulated (30V) outputs must not exceed 0.7 A.

• Heat Dissipation: While the module is fan-less, ensure proper cabinet ventilation as it dissipates approximately 9 W at full load.

• Fused Protection: The module uses a 2 A fast-acting fuse for input protection. Always replace with the same rating to maintain safety certifications.

• Discontinued Status: Please note that the PS-502 series is largely considered a legacy product. Ensure spare parts are sourced from certified refurbished vendors if new units are unavailable.

Product Applications

The PS-502-A1 is predominantly used in:

1. Safety Instrumented Systems (SIS): Specifically within the Yokogawa ProSafe-SLS architecture.

2. Loop Powering: Providing clean 24V power to analog 4-20mA loops.

3. Field Instrument Supply: Powering transmitters, solenoid valves, and other field devices in hazardous or high-interference environments.
