Core difference from 14A0041G02

14A0041G02: Standard power, 24VDC/6.5A (approximately 150W)

14A0042G01: High power, 24VDC/20A (approximately 480W), with an auxiliary 24V output

Application scenarios: 41G02 is used for ordinary I/O racks; 42G01 is used for fully equipped I/O + controller heavy-load racks Functional Features

Ultra-high power density: 24VDC/20A main output + 24VDC/10A auxiliary output, total power 480W

Wide input voltage: 85–264VAC, 50/60Hz, universal for global power grids

Redundancy and hot-swapping: Supports N+1 parallel redundancy, online replacement without stopping

Industrial-grade protection: Overvoltage, overcurrent, short circuit, overheating, input reverse polarity protection

Low ripple: Output ripple < 50mVpp, protects precision measurement cards

Dual output: Main 24V (I/O/ controller) + auxiliary 24V (loop / contact wetting)

Status diagnosis: Power normal, fault, alarm dry contact output, can be sent to DCS
