3PS465.9 General Information

Power supply modules create the voltages required internally by the PLC from a 24 VDC input

voltage. Each main and expansion unit requires its own power supply module. The power supply

module always has to be operated in the far left slot of the backplane. All power supply modules

require two slots.

3PS465.9 Overview

1.2 Slots

The power supply must always be located on the far left slot.

When configuring a system, make sure that the power consumption of all modules installed is

not larger than the output power of the power supply module. If a power supply unit cannot

provide the power required by the modules, install the I/O modules on an expansion backplane.

2 Current Limitation

Power supply modules are equipped with an internal current limit (short circuit protection) and

have connections for an external buffer voltage (AC240 battery module). The current limitation

is also activated if the modules require more power than the power supply can deliver. This

causes a reset on the CPU without a power failure having occurred.

3. READY Relay

If a reset occurs, the ready relay reacts to a loss in current by stopping the entire PLC through

the programming system. It can be set or reset by the operating system. Errors that cause the

relay to open are defined in the operating system.

It is also possible using software to define other errors that should cause a drop in the ready

relay. The ready relay is coupled with the status LED “RUN” on the CPU.
The READY relay is controlled by the CPU. Therefore the pin assignments listed

for the power supply PS477 are only valid for use in a main backplane.

Wiring the ready relay is carried out using the 10-pin terminal block. The ready relay contact can

be integrated in the emergency stop circuit:
