Product Overview The Woodward 5466-318 TMR Kernel PS Module regulates 24 Vdc input to a stable 5 Vdc output at 10 A. It powers all kernel components within the MicroNet Digital Control system. This module ensures safe startup by generating a 5 Vdc precharge voltage, protecting sensitive circuits from power surges. Each 5466-318 module installs in the first slot of the kernel sub-chassis. The adjacent slot must house the Kernel CPU module to maintain correct system configuration. A single LED on the module indicates power health status. Technical Specifications Parameter Specification Manufacturer Woodward Model Number 5466-318 Series MicroNet Digital Control Input Voltage 24 Vdc Output Voltage 5 Vdc Output Current 10 A Operating Current 4 mA Dimensions 16 cm × 16 cm × 12 cm Weight 0.8 kg LED Indicator 1 (Power Health Status) Slot Position First slot in kernel sub-chassis Installation Notes Install the 5466-318 module in the leftmost slot of each kernel sub-chassis. Place the Kernel CPU module immediately to its right. This layout ensures optimal performance and system integrity. Application & Compatibility The Woodward 5466-318 module supports fault-tolerant operation in MicroNet TMR control systems. It suits high-reliability environments such as nuclear facilities, aerospace platforms, and mission-critical industrial automation. Its modular redundancy allows independent kernel operation during power faults, enhancing system uptime. Compatible with MicroNet chassis configurations requiring regulated 5 Vdc distribution.
