IC693PWR332 High Capacity Power Supply, 12 VDC Input The Series 90-30 DC input High Capacity power supply (IC693PWR332) is a 30 watt wide range supply designed for 12 VDC nominal input power. It will accept an input voltage range from 9.6 VDC to 15 VDC. This power supply provides the following outputs: +5 VDC output. +24 VDC Relay power output which provides power to circuits on Series 90-30 Output Relay modules. Isolated +24 VDC, which is used internally by some modules, can also be used to provide external power for 24 VDC Input modules. The load capacities for each output of the power supply are shown in the following table. Table 4-12.

Multiply the output power by 1.5 to determine the input power value. Divide the input power value by the operating source voltage to determine the input current requirements Use the lowest input voltage to determine the maximum input current Allow for start-up surge current requirements Allow margins (10% to 20%) for variations Series 90 30 Power Supplies 4 GFK 0898F Chapter 4 Series 90 30 Power Supplies 4-19 Field Wiring Connections to the DC Input-Only Power Supplies DC Power Source Connections The + and wires from the DC power source connect to the top two terminals on the terminal strip. The + wire should be connected to the top terminal screw, and the wire to the second screw (counting from the top down). The ground connection connects to the third screw. This connection scheme is clearly marked on the front of these power supplies. + 24 VDC OUTPUT 0.8A MAX.

The purpose of these LEDs is as follows: PWR The top green LED, labeled PWR, provides an indication of the operating state of the power supply. The LED is ON when the power supply has a correct source of power and is operating properly, and OFF when a power supply fault occurs or power is not applied. OK The second green LED, labeled OK, is steady ON if the PLC is operating properly, and OFF if a problem is detected by the PLC. RUN The third green LED, labeled RUN, is steady ON when the PLC is in the RUN mode. BATT The bottom red LED, labeled BATT, will be ON if the memory backup battery voltage is too low to maintain the memory under a loss of power condition; otherwise it remains OFF. If this LED is ON, the Lithium battery must be replaced before removing power from the rack, or PLC memory may be lost. Input Overvoltage Protection Devices This information applies to all Series 90-30 power supplies that have six terminal boards. The overvoltage protection devices for this power supply are connected internally to pin 4 on the user terminal strip. This pin is normally connected to frame ground (pin 3) with the supplied jumper strap which is installed at the factory. If overvoltage protection is not required or is supplied upstream, this feature can be disabled by removing the jumper strap from pins 3 and 4. If you want to Hi-pot test this supply, overvoltage protection must be disabled during the test by removing the terminal strip jumper strap. Re-enable overvoltage protection after testing by reinstalling the strap.
