The ABB Bailey IEPAS01 is an AC System Power Module for the INFI 90 Modular Power System. It converts 120/240 VAC line power into the regulated DC voltages required by INFI 90 process control modules.
The IEPAS01 provides +5 VDC, +15 VDC, -15 VDC, and +24 VDC outputs. These voltages are distributed through the Module Mounting Unit backplane and DC bus structure to installed process control modules.
The module accepts either 120 VAC or 240 VAC input through a configurable jumper arrangement. Bailey specifies a 47 to 63 Hz operating frequency and a maximum input current of 1.6 A per power supply module.
The INFI 90 power architecture also supports multiple IEPAS01 modules operating in parallel. This allows additional modules to be installed for increased system capacity or N+1 redundancy.
| Parameter | Specification |
|---|---|
| Manufacturer | ABB Bailey |
| Model | IEPAS01 |
| Product Family | INFI 90 |
| Product Type | AC System Power Module |
| Primary Function | INFI 90 system DC power generation |
| Mounting | INFI 90 Module Mounting Unit |
| Redundant Operation | Supported |
| Provided Power Rating | 250 VA |
| Parameter | Specification |
|---|---|
| 120 VAC Operating Range | 102 to 132 VAC |
| 240 VAC Operating Range | 204 to 264 VAC |
| Input Selection | 120/240 VAC jumper configurable |
| Input Frequency | 47 to 63 Hz |
| Maximum Input Current | 1.6 A per power supply module |
| Inrush Current | Less than 15 A per module, fully loaded |
The Bailey E96-506 manual specifies both the 120 VAC and 240 VAC operating ranges for IEPAS01 and IEPFA01 power modules.
| Output | Rated Capacity |
|---|---|
| +24 VDC | 25.5 VDC output, 4 A |
| +5 VDC | 5.1 VDC output, 10 A |
| +15 VDC | 0.5 A |
| -15 VDC | 0.5 A |
The manual identifies the IEPAS01 as the system power module providing the four required INFI 90 DC supply rails.
| Parameter | Specification |
|---|---|
| Line Regulation | 0.5% |
| Hold-up Time | Greater than 20 ms, fully loaded |
| Maximum Heat Dissipation | 25 W per module |
| Nominal System Rails | +5, +15, -15, +24 VDC |
The Modular Power System specifications give a hold-up time above 20 ms and maximum heat dissipation of 25 W per module.
The IEPAS01 converts the incoming 120/240 VAC supply to a nominal intermediate DC voltage.
Internal DC/DC conversion stages then generate the four regulated system outputs:
These outputs are routed through the DC bus bar and Module Mounting Unit backplane to the installed INFI 90 process control modules. The Bailey system block diagram shows the IEPAS01 as the system-power source feeding these four rails.
Multiple IEPAS01 modules can share the system load.
Bailey describes the Modular Power System as supporting N+1 redundancy. Additional power modules can be installed beyond the minimum number required by the cabinet load.
This architecture allows a power module to be removed or fail while remaining modules continue supplying the required load, provided sufficient capacity remains.
The IEPAS01 uses J1 to select the AC input configuration:
| Supply | J1 Setting |
|---|---|
| 120 VAC | Position A |
| 240 VAC | Position B |
The manual also identifies J2 as part of the bus-voltage monitoring configuration. For IEPAS01 installation, Bailey instructs J2 to use the position for monitoring +5, +15, -15, and +24 VDC.
The quick-reference table confirms J1 Position A for 120 VAC and J1 Position B for 240 VAC operation.
Bailey specifically warns that the power module contains ESD-sensitive circuitry and states that the output adjustment potentiometers are factory-set and should not be readjusted.
The Bailey manual explicitly distinguishes the two modules: IEPAS01 provides +5, +15, -15, and +24 VDC, while IEPAF01 provides +24 VDC only for field-powered devices.
| Parameter | Specification |
|---|---|
| Room Ambient Temperature | 0 to 55 degC |
| Maximum Module Ambient Temperature | 70 degC |
| Maximum Baseplate Temperature | 85 degC |
| Humidity at up to 55 degC | 5% to 90%, noncondensing |
| Humidity at 70 degC | 0% to 45%, noncondensing |
| Maximum Altitude | Sea level to 3 km |
| Air Quality | Noncorrosive |
These environmental limits are specified for the INFI 90 Modular Power System hardware.
