Power supply modules
Quantum power supply modules serve two purposes - they provide power to the
system rack and protect the system from noise and voltage swings. Power supply
modules feature overcurrent and overvoltage protection. They operate in most
electrically noisy environments without the need for external isolation transformers.
In the event of an unforeseen loss of power, the power supply modules help ensure
that the system has adequate time for a safe and orderly shutdown. A power supply
module converts the input voltage to regulated + 5 V DC for the requirements of the
CPU, the I/O modules and the communication modules installed in the rack. The
power between the sensors/preactuators and the I/O points on the Quantum system
is not provided by these power supply modules.
Three types of power supply module are available for use in local or remote (RIO)
architectures:

For distributed I/O (DIO) architectures, low power standalone power supplies are
available. These are dedicated to distributed architectures and integrated in
distributed I/O drop adaptors. Distributed power supplies are described in the pages
on the distributed I/O architecture.
A standalone power supply module provides a 3 A current to the Quantum rack.
When the system only requires low power, a standalone power supply module is an
economical choice. These standalone power supply modules are available for
115/230 V a, 24 V c and 125 V c supply voltages.
A summable power supply module provides a 8 A or 11 A current to the Quantum
rack. These summable power supply modules can operate in either standalone or
summable mode. When two summable power supply modules are installed in the
same rack, they automatically operate in summable mode, providing a current of
16 A or 20 A (depending on the model). In summable mode, both power supply
modules must be the same type and must be installed in the left and right end slots of
the rack for maximum life. If one of the two power supply modules fails, power is lost
to the rack.
If only one summable power supply module is installed in a rack, it operates in
standalone mode, supplying a current of 8 A or 11 A to this rack.
Summable power supply modules are available for 115/230 V a, 24 V c and
48/60 V c supply voltages.
A redundant power supply module provides a current of 8 A or 11 A (depending on
the model) to the Quantum rack. For high-availability applications, two redundant
power supply modules will provide a redundant current of 8 A or 11 A.
If one of the two power supply modules becomes inoperable, the one that remains
operational maintains the supply of the required power. Each redundant power
supply module has a status bit that can be monitored by the application program or
by a supervision system, in order to react quickly if the power supply is interrupted.
If an additional power supply module is necessary in a configuration with redundant
power supply modules, a third redundant power supply module can be added to the
rack, increasing the available capacity to 16 A or 20 A. If one of the three power
supply modules becomes inoperative, the remaining operational modules revert to
standard redundant mode, supplying a redundant current of 8 A or 11 A to the rack.
A redundant power supply module can be used as a standalone power supply
module.
Redundant power supply modules are available for 115/230 V a, 24 V c,
48/60 V c and 125 V c supply voltages.
