Product Overview

The IPSYS01 is a rack‑mounted system power module for ABB Symphony Plus Harmony Rack I/O DCS platforms, delivering regulated 5 VDC, 15 VDC, ‑15 VDC backplane power to controllers and I/O cards inside the control rack. It accepts both AC and DC main‑supply inputs and supports parallel redundant deployment with active current‑sharing to balance load distribution across multiple power units. Front‑panel bi‑color LED indicators report module health, output status and fault conditions for quick on‑site visual diagnostics.

This power module addresses critical high‑availability control‑system risks: unstable backplane voltages from mains fluctuation, single‑point power‑supply failure, and short‑circuit damage propagating across rack hardware. Redundant configurations allow hot‑swap replacement of one power unit without disrupting running DCS operations. Power‑plant control engineers, DCS retrofit specialists and site‑maintenance teams benefit most. It fits standard Harmony power‑chassis slots, works alongside IPMON01 power‑monitor hardware for remote system‑power alarm reporting, and serves as drop‑in spare hardware for legacy Bailey‑originated DCS installations within power‑generation, water‑treatment and process‑manufacturing facilities.

Key Application Notes

• Supplies system logic voltages for rack‑based I/O and controllers; field‑side 24 VDC I/O power requires separate IPFLD01 / IPFLD24 field‑power modules
• Mixed AC‑and‑DC input sources are permitted for redundant 2N power‑supply configurations
• Conformal‑coated PCB variant options are available for cabinets with elevated humidity and airborne‑contaminant exposure
• Hot‑swap capability only applies in multi‑module redundant power‑supply setups
• System‑level power‑health status can be forwarded to DCS HMI when paired with IPMON01 monitoring module
