MeloAuto-Trusted PLC & DCS Parts Supplier
The ABB Bailey IEPEP03BRC-100 converts analog field signals into digital process data. This module handles eight differential input channels with high precision. It weighs approximately 0.62 kg and fits any standard Bailey rack slot. Its dimensions measure 25.4 cm in length, 12.7 cm in width, and 3.2 cm in height.
Technical Specifications & Hardware Details
The IEPEP03BRC-100 provides eight isolated analog input channels for noise rejection. A single 48-pin backplane connector links this module to the host controller. This unit stores no energy internally because it contains no batteries. Four main components form the complete assembly: the PCB, the faceplate, the backplane connector, and the isolation barrier.

Signal Accuracy and Field Wiring
You can connect 2-wire or 4-wire transmitters directly to the IEPEP03BRC-100. Each channel includes individual isolation to prevent ground loop errors. For terminating field wiring, use external termination units with screw terminals. The input impedance measures 250 Ω for current mode and 100 kΩ for voltage mode.
Installation and Operational Data
You can mount this module into any open slot of a Bailey INFI 90 rack. The module draws 220 mA from the 5V backplane supply during normal operation. Furthermore, it operates reliably within a -10°C to 65°C temperature range. Consequently, the IEPEP03BRC-100 requires zero scheduled maintenance. Just inspect field wiring connections during routine system shutdowns.
