Engineered for ABB Bailey INFI 90 Power Supply Supervision
This module monitors voltage and current levels for system power supplies. It provides real-time power data for the ABB Bailey IEPWM02 unit. You will find this power monitor in INFI 90 control racks. Unlike basic indicators, this version measures multiple DC voltage rails. It tracks both supply health and load conditions continuously.

Functional Architecture and Measurement Features
This power monitor connects to multiple DC power distribution points. It uses separate measurement circuits for each voltage rail. You can view voltage and current readings on the front display. Moreover, the module includes programmable high and low trip limits. These components trigger alarms when power deviates from normal range. Consequently, operators receive early warning of impending power supply failures.
Installation and Operational Guidelines
The ABB Bailey IEPWM02 consumes 100 mA at 24V DC for its own circuits. It samples all monitored rails every 250 milliseconds. You must connect the monitor after the main power distribution breaker. Always use appropriately sized fuses for current measurement inputs. This practice protects the monitor from overload damage. Furthermore, the module includes a relay output for remote alarming. This feature connects directly to plant annunciator systems.
Physical Characteristics and Environmental Limits
This power monitor has a rugged, metal-reinforced plastic housing. Its substantial 0.68 kg weight reflects the internal measurement circuitry. The layout follows ABB Bailey standard INFI 90 specifications. Therefore, it mounts securely in dedicated monitoring slots or panels. The module includes a front panel for local reading access. In addition, it maintains stable operation between 0°C and 55°C ambient temperature. You can store this unit safely between -20°C and 70°C.
