1C31233G04 high-power redundant power supply module

1C31233G04 is a high-power redundant power supply module developed by Emerson (originally Westinghouse) for its Ovation Distributed Control System (DCS). It is specifically designed to provide stable, uninterrupted DC power for Ovation I/O racks, controllers, and communication modules in industrial control systems. With built-in redundancy support and multi-layer protection, it is a core power component for ensuring continuous operation of safety-critical industrial processes. Below is its detailed information:

1. Core Technical Specifications

Parameter Category	Specific Details
Input Power Parameters	- Input Voltage Range: 100–240V AC (wide-range design, compatible with global industrial power grids; no need for voltage switching between 110V/220V regions).- Input Frequency: 50/60Hz (adapts to standard industrial power frequency).- Input Current: ≤6A (maximum at 100V AC input); Overload Capacity: 120% of rated input current for 15 seconds (withstands transient power surges during system startup or simultaneous activation of multiple I/O modules).
Output Power Parameters	- Primary Output: 24V DC, 10A (total output power 240W)—sufficient to power 15–20 Ovation I/O modules (e.g., 1C31205G01 digital input modules) or a full Ovation I/O rack (including controllers and communication cards).- Voltage Regulation: ±0.3% (high precision, ensuring no signal drift for precision analog modules like 1C31179G02 RTD/temperature input modules).- Ripple & Noise: ≤30mVpp (low ripple, avoiding electromagnetic interference to sensitive circuits such as HART communication channels).
Redundancy & Protection	- Redundancy Support: Supports 1+1 redundant parallel operation (two modules working in parallel). If one module fails, the other automatically takes over full load within ≤10ms, ensuring no power interruption.- Comprehensive Protection:1. Overcurrent protection: Limits output current to 12A (self-recovery mode); resumes normal output after fault clearance.2. Overvoltage protection: Shuts down when output voltage exceeds 27.6V DC, preventing damage to DCS components.3. Over-temperature protection: Activates at 85°C (internal temperature); restarts automatically after cooling to 60°C.4. Undervoltage lockout: Disables output when input voltage drops below 85V AC, avoiding unstable power supply.
