The 1746-P4 SLC 500 power supply module efficiently delivers backplane power to either a local chassis, expansion module, or remote I/O chassis, enabling module recognition by the SLC processor. It operates on an input voltage range of 85 to 132V AC or 170 to 250V AC at 47 to 63 Hz and features a 24V DC output dedicated for external devices, although not recommended for output modules to facilitate easier troubleshooting. Featuring a hold-up time of 20 ms at full load and 3000 ms under no load conditions, this module maintains logic processing during power dips until voltage is restored to optimal levels. Additionally, this unit holds UL listing as Industrial Control Equipment and CSA certification for use in Class 1, Div 2 hazardous locations.
