1 Power Supplies IC697PWR720 11 Power Supply Adapter Module GFK-0626D August 1997 Power Supply Adapter Module (IC697PWR720) datasheet GFK-0626D Features H H H H a44940 Interfaces an external power supply to an IC697 rack Single-slot module Plugs into power supply slot in rack Easy connection to power supply Functions This Power Supply Adapter Module (PSA) for the IC697 I/O system is a single-slot module that plugs into the power supply slot, which is the leftmost slot in an IC697 rack. The PSA module must be connected to an external power supply through a cable. The external power supply can be an IC697 power supply module (see GFK-0717), or other external power supply. The +5, +12, and –12 VDC outputs, as well as the 5V remote sense, which are generated by an external power supply are connected to the IC697 rack backplane through the PSA. The maximum currents that can be supplied to the backplane through the PSA are: 18 amps on the +5 volt output, 2 amps on the +12 volt output, and 1 amp on the –12 volt output. The PSA monitors the +5 volt output and the ttl compatible Input Power OK signal (TTL) from the external power supply. The Input Power OK signal (TTL) indicates that the external power supply input voltage is adequate to maintain hold-up time for an orderly system shutdown. The PSA also develops two backplane signals, ACFAIL* and SYSRESET*, which are for the power-up/power-down sequence. The external power supply must provide adequate hold-up time (5.05 milliseconds minimum, per ANSI/IEEESTD1014-1987) as well as an Input Power OK signal (TTL) to ensure an orderly system shutdown when power is removed. t Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F NC 1PL–1 0V 1PL–2 0V 1PL–3 0V 1PL–4 0V 1PL–5 5V 1PL–6 5V 1PL–7 5V 1PL–8 5V 1PL–9 CKT NAME CKT NAME TERM NO TERM NO NC 1PL–10 12V 1PL–11 12V 1PL–12 5VS 1PL–13 0VS 1PL–14 TTL 1PL–15 JP1 1PL–16 JP0 1PL–17 NC 1PL–18 ÎÎ Î ÎÎ Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î Î PWR 720 WARNING EVEN IF THE POWER SUPPLY IS SWITCHED OFF, HAZARDOUS VOLTAGES FROM USER FIELD WIRING MAY STILL BE PRESENT ON THE I/O TERMINAL BOARDS AS WELL AS THE POWER SUPPLY TERMINAL BOARD. CARE SHOULD BE TAKEN WHEN HANDLING THE POWER SUPPLY AND I/O MODULES AS WELL AS ANY WIRING CONNECTED TO THEM IN ORDER TO PREVENT PERSONAL INJURY. WARNING DO NOT REMOVE OR INSERT MODULES WITH POWER APPLIED. PERSONAL INJURY, SYSTEM MALFUNCTION AND/OR DAMAGE TO THE EQUIPMENT MAY OCCUR. MODULE IC697PWR720 LABEL44A726758–504R01 It is recommended that the external power supply have a +5V Remote Sense. When the Remote Sense is connected to the PSA terminal board (positive remote sense to +5VS and negative to 0VS) the +5 volts at the backplane will be regulated to the level set by the power supply. 11-1 Power Supplies 2 GFK-0626D August 1997 Power Supply Adapter Module The LED indicator on the PSA is ON when the +5 volt output is in regulation at the backplane and the TTL signal from the power supply indicates that the power supply input voltage is adequate to maintain hold-up time for an orderly system shutdown. This TTL signal can be positive or negative logic. Two terminals on the PSA terminal board (JP1 and JP0) are available for selecting the logic state. If positive logic (Input Power OK if TTL = high), no jumper is required; if negative logic (Input Power OK if TTL = low), a jumper is required between terminals JP1 and JP0. Mounting The Power Supply Adapter is a single-slot module that plugs into the power supply slot, which is the leftmost slot of an IC697 rack. It connects to the external power supply module through a cable that has one end connected to the power supply. The free end of the cable should have spring spade or ring lugs which must be connected to designated terminals on a terminal board on the Power Supply Adapter. This terminal board is accessed by opening the hinged door on the Power Supply Adapter module. Operation of the Power Supply Adapter This Power Supply Adapter Module operates from +5 VDC power which it receives from the +5 VDC power bus on the IC697 rack backplane. Power Supply Adapter Module Door The Power Supply Adapter door can easily be opened by grasping the upper left corner of the door with your right thumb or a fingernail and gently pulling the door towards you. Use care when opening the door since pulling from the bottom can cause the hinge or the door to break. Dual Rack Operation A single external power supply can provide power for two racks. In this application, the PSA must be installed in the first rack. For detailed information on this application, refer to the applicable Programmable Controller Installation Manual. a44936 ÎÎ Î Î Î Î ÎÎ Î Î Î ÎÎ Î Î Î Î ÎÎ ÎÎ Î Î ÎÎÎ Î ÎÎÎÎ Î Î ÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎ Î ÎÎÎ Î Î ÎÎÎÎÎÎ Î Î ÎÎÎÎÎ Î ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ Î ÎÎÎ Î ÎÎÎ ÎÎÎ Î Î ÎÎÎ ÎÎ Î Î ÎÎÎ Î ÎÎÎ Î ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎÎÎ ÎÎ ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎÎ Î ÎÎ Î Î ÎÎÎ ÎÎÎ Î Î ÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎ Î ÎÎÎ Î Î Î Î ÎÎÎÎÎ Î ÎÎÎ Î Î LOGICPOWER POWERSUPPLY POWERSUPPLY ADAPTER OK OK OK OK RUN PGMRACTIVE USER 1 CH 1 OK ENABLED BUSACTIVE USER 2 CPU BUS PROGRAMMABLE Bus INPUT INPUT INPUT OUTPUT OUTPUT TRANSMITTER COPROCESSOR CONTROLLER 120VAC 120VAC 120VAC 120VAC, 05A 120VAC,.05A PROGRAMMABLE CONTROLLER Figure 1.
