Bailey IEPAF02 AC Field Power Supply Unit

The IEPAF02 AC Field Power Module is a Bailey Infi-90 field power supply that provides a dedicated +24 VDC rail for field termination devices or for powering separate field cabinets from the Infi-90 backplane. It is functionally the same as the IEPAS02 system power module, but delivers only +24 VDC (the IEPAS02 supplies +5, +15, -15, and +24 VDC to the backplane). The module accepts 120 VAC (47–63 Hz) at 2.2 A or 220 VAC (47–63 Hz) at 1.2 A and outputs a regulated +24 VDC to field devices. This arrangement lets Infi-90 installations isolate field-side power from system power, enabling independent field power provisioning for sensors and actuators while the central backplane distribution remains dedicated to control modules.
