621-9934C I/O Rack Power Supply | Honeywell

The 621-9934C is an I/O rack power supply module designed for Honeywell IPC 620 and Universal Control Network (UCN) systems. It accepts dual voltage inputs of 115 VAC or 230 VAC to deliver a regulated 24 VDC output, providing stable power to logic managers and associated I/O modules across industrial automation architectures.

Power Input and Output Regulation

The module accommodates selectable AC input voltages, allowing deployment across standard 115 VAC and 230 VAC power grids. It converts incoming AC power into a steady, regulated 24 VDC output designed with low ripple and built-in overload protection to maintain consistent module operation.

Physical Configuration

Weighing approximately 1.45 kg to 1.6 kg, the unit features a slim profile engineered for straightforward integration into control racks. Depending on the mounting configuration and source reference, dimensional metrics are noted as 94 x 106 x 22 mm or alternatively up to 264 x 32 x 127 mm.
