1C31234G01 high-reliability power supply module

1C31234G01 is a high-reliability power supply module developed by Westinghouse (now integrated into Emerson Automation Solutions) for its Ovation Distributed Control System (DCS). It serves as the core power source for Ovation system racks, providing stable and redundant DC power to I/O modules, communication modules, and controllers, ensuring continuous operation of the entire control system in harsh industrial environments. Below is its detailed information:

1. Core Technical Specifications

Parameter Category	Specific Details
Power Output	- Output voltage: 24V DC (regulated, output voltage deviation ≤±1%, ensuring stable power supply for Ovation modules).- Output current: Typical 10A (maximum 12A), capable of powering multiple rack-mounted modules (e.g., 16+ I/O modules or a combination of controllers and communication modules).
Input Power	- Input voltage: 100–240V AC (wide-range adaptation, compatible with global industrial power grids; 50/60Hz frequency, no manual adjustment required).- Input current: 3A (at 100V AC) / 1.5A (at 240V AC), with inrush current suppression to avoid grid impact during startup.
Redundancy Support	Supports 1+1 redundant configuration (two modules share the load and back up each other). If one module fails, the other automatically takes over full load without power interruption, meeting safety-critical system requirements.
Protection Mechanisms	- Over-voltage protection (OVP): Triggers shutdown when output voltage exceeds 27V DC, preventing damage to downstream modules.- Over-current protection (OCP): Limits output current to 13–15A (adjustable), avoiding overload caused by short circuits or excessive module quantity.- Over-temperature protection (OTP): Shuts down when internal temperature exceeds 85°C, preventing component burnout due to high temperatures.- Short-circuit protection: Instantly cuts off output when a short circuit occurs, and automatically recovers after the fault is cleared.
