HONEYWELL 620-0083 Processor Power Supply Module

The 620-0083 is a high-capacity processor power supply module manufactured by Honeywell for the IPC 620 programmable controller system. It accepts a user-selectable AC line input of 115 VAC or 230 VAC (47 to 63 Hz) and provides regulated DC voltage outputs (+5 VDC and +/- 15 VDC) directly across the chassis backplane. Delivering up to 90 W of continuous power, this unit energizes local processor modules and system logic cards.

Input Power and Voltage Selection

The module operates on standard AC mains power with a dual-voltage input rating of 115 VAC or 230 VAC at 47 to 63 Hz, drawing a maximum power consumption of 110 VA. Internal power regulation components convert AC line voltage into stable DC power rails required by IPC 620 rack logic assemblies.

DC Power Distribution and Current Limits

Power distribution across the backplane bus is divided into distinct DC voltage rails with specific current capacity thresholds:

• +5 VDC Rail: Supplies main logic circuits with a maximum current output of 15 A.
• +/- 15 VDC Rails: Provides auxiliary power for analog and interface circuitry with a maximum current output of 2 A.
• Total DC Power Output: Capped at 90 W maximum across all combined output channels.

Frequently Asked Questions

Q: What AC line voltages are supported by the Honeywell 620-0083 power supply?
