Bailey Infi 90 Power Entry Circuit Breaker

The IPCHS01 Power Module Chassis provides power input connection, power output bus bars,

and various terminals for status inputs and outputs. It provides mounting for up to eight power

modules and one power monitor module. There are nine mounting slots total. The center slot is

dedicated to the power monitor module. Four slots on each side of the power monitor module

hold power modules and have isolated power inputs.

All the power module outputs share the same bus. System power for the cabinet is made available

at bus bars on the power module chassis backplane and at terminal strips (for ±15 VDC and

48/125 VDC). Cables connect the bus bars and ±15 VDC terminals to the system power bus bar for

distribution to the cabinet. The 48/125 VDC terminals are user outputs.

Power modules and the power monitor module can be removed from the power module chassis

and replaced while the system is on-line. Only IPSYS01, IPFLD01, IPFLD24, IPFLD48, and

IPFLD125 power modules and the IPMON01 power monitor module can be mounted in this

power module chassis. The IPFLD48 and the IPFLD125 power modules cannot coexist in the same

power module chassis.

Power Entry Circuit Breaker or Switch

The IPECB11 or IPECB13 Power Entry Circuit Breaker and IPESW11 or IPESW13 Power Entry

Switch terminate the AC or DC power input lines and provide line filtering before feeding power

to the power module chassis backplane. These devices mount on the back of the power fan chassis.

One circuit breaker or switch is used on N, N+1, and N+x redundant systems (Fig. 2); two are

used on 2N redundant systems (Fig. 3). The isolated inputs on 2N redundant systems allow for

mixed power inputs (i.e., 125 VDC and 120/240 VAC) because two separate power entry circuit

breakers or switches feed isolated power inputs to the power module chassis. 

Applications

The binary input board 23BE40 performs the following processing functions for different types of signals:

 Digital filtering to suppress contact jumping

 Suppression of technically induced chattering signals

 Intermediate position suppression and double indication monitoring

 Consistency check of all binary input channels assigned to digital measurement values

The 23BE40 has a buffer for temporarily storing 50 time-stamped event messages in chronological order, designated for transmission to the communication unit.

The board's microcontroller handles all time-critical tasks for the parameterized processing functions. In addition, it communicates interactively with the RTU560 system bus.

All configuration data and processing parameters are transmitted via the RTU560 system bus.

All configuration data and processing parameters are loaded from the communication unit via the RTU560 bus.

The board is equipped with a serial interface to the RTU560 system bus.

During initialization and operation, the board performs a series of tests. If a fault occurs, it is reported to the communication unit.

All fault conditions affecting the board's functionality are indicated as general fault signals by means of light emitting diodes (ST).

Faults in the board are detected by the communication unit.
