Supply
DC Power Source Connections
The + and – wires from the 12 VDC power source
connect to the top two protected terminals on the powers
supply terminal board. Connect the + wire to the top
terminal and the – wire to the second terminal. A
connection diagram is printed on the front of the power
supply module next to the terminal board.
Isolated 24 VDC Supply
The following graph is a typical 12 VDC power supply
efficiency curve. A basic procedure for determining the
input power requirement of the 12 VDC power supply
follows the figure.

The bottom two terminal board terminals provide
connections to the Isolated 24 VDC output. This output
can be used to provide power for input circuits for 24
VDC Input Modules (within the 15 watt limitation of this
output). This is useful because power switched to input
points must be supplied from a source external to the
IC693 input modules.

Wire Connection information
•
Each terminal can accept solid or stranded wires, but,
if using two wires on one terminal, the wires should
be the same size and type.
•
The suggested torque for the power supply terminal
board screws is 12 in-lbs. (1.36 Nm).
•
Use one AWG #14 (2.1 mm2) or two AWG #16 (1.3
mm2) copper conductors, rated for 75 degrees C (167
degrees F) only, per terminal board terminal.
Figure 2. Typical Efficiency Curve
Note
Start-up surge at full load is 4 amps for 250
milliseconds (maximum)
Use These Steps for Calculating
Input Power Requirements
•
Input Overvoltage Protection Devices
The input overvoltage protection devices are connected
internally to pin 4 of the terminal board. This pin is
normally connected to pin 3 (frame ground) via a factoryinstalled jumper strap. If a Hi-Pot test is to be performed
on this supply, the jumper strap must be removed during
the test so that the overvoltage protection devices are not
damaged. After testing, replace the jumper strap to
restore overvoltage protection during normal operation.
•
•
Determine total output load from typical
specifications listed for individual modules in the
IC693 PLC Installation and Hardware Manual.
Multiply the total output load, determined in the
previous step, by 1.5 to determine input power value.
Divide the input power by the operating source
voltage to determine the input current requirement.
Since operating source voltage may vary, use the
lowest measured or estimated input voltage to
determine the maximum input current.
•
Allow for start-up surge current requirements.
•
Allow margin (10% to 20%) for variation.

Status Indicators on Power Supply
Overcurrent Protection
The power supply has four LEDs located at the top, right
corner of the power supply faceplate. These LEDs
provide the following status indications:
The +5V logic output is electronically limited to 7 amps.
An overload (including short circuits) of the output power
is sensed internally and causes the supply to shut down.
The supply will continually try to restore power until the
overload is removed.
PWR
An internal fuse in the input line is provided as a backup.
The supply will usually shut down before the fuse opens.
The fuse protects against internal supply faults.
The top green LED, labeled PWR, provides an indication
of the operating state of the power supply. The LED will
be ON when the power supply has a correct source of
power and is operating properly, and OFF when a power
supply fault occurs or if power is not applied.
Timing Diagram
The timing diagram below shows the relationship of the
DC input to the DC outputs and to the Power Supply OK
(PSOK) signal generated by the power supply. When
power is first applied, the PSOK signal goes false. This
line remains false for a minimum of 20 msec after the
+5V bus is within specifications, then it becomes true.
OK
The second green LED, labeled OK, will be ON if the
PLC is operating properly, and OFF if a problem is
detected by the PLC.
RUN
If DC input power is interrupted, the +5V bus will remain
within specifications and PSOK will remain true a
minimum of 10 milliseconds (“ride-through time”).
PSOK then goes false. The +5V bus will remain within
specifications for an additional 4 milliseconds minimum
to allow an orderly shutdown of the system.
The third green LED, labeled RUN, will be ON when the
PLC is in the RUN mode, and OFF when the PLC is
stopped.
BATT
The bottom red LED, labeled BATT, will be ON if the
RAM memory backup battery voltage is too low to
maintain memory contents under a loss of power
condition. Otherwise it remains OFF. If this LED is ON,
the battery should be replaced – refer to the information
in the Warning message on the next page.

Note
CPU Serial Port Connector on Power Supply
A 15-pin D-type female connector is accessed by opening
the hinged door on the right front of the power supply. It
provides the connection to a PLC serial port used for
communicating with (1) a programmer (Personal
Computer) running PLC programming software, (2) the
IC693 Hand-Held Programmer, or (3) other serial
devices. The PLC serial port is RS-485 compatible and
supports the Series Ninety Protocol (SNP) for serial
communications.
a43832
The serial port is not functional on a power
supply that is installed in an Expansion or
Remote type baseplate.
Any device connected to the serial port that uses +5VDC
power from the power supply, such as the IC693ACC901
Miniconverter, must be included in the calculation for
maximum power consumption. For more information,
see the IC693 PLC Installation and Hardware Manual.
Backup Battery for RAM Memory
The long-life Lithium battery (IC693ACC301) used to
maintain the contents of the CMOS RAM memory in the
CPU is accessed by removing the cover plate located at
the bottom of the power supply faceplate. This battery is
mounted on a plastic clip attached to the inside of this
cover.
RS-485
COMPATIBLE
SERIAL PORT
Figure 4. Serial Port Connector
The battery connects to the power supply by a pair of
wires that terminate in a connector that plugs into a
mating connector on the power supply circuit board (see
next figure). To avoid loss of PLC RAM memory
contents, refer to the instructions in the following
Warning message:
WARNING
CPU Serial Port Considerations
The serial port connector is only functional in a power
supply that is installed in a CPU baseplate. This includes
all models of the embedded CPU baseplates (CPU311 –
CPU323) as well as all models of the modular CPU
baseplates (CPU350 – CPU364).
If a Low Battery Warning (BATT LED is ON) occurs,
replace the battery in the power supply before
removing power from the PLC rack to avoid possible
loss of PLC RAM memory contents. However,
exercise extreme caution because lethal voltages may
be present in the enclosure or area. Failure to heed
this warning could result in personal injury or death.
