电源适配器模块
功能IC697 I/O系统的此电源适配器模块（PSA）是一个单插槽模块，可插入电源插槽，该插槽是IC697机架中最左边的插槽。PSA模块必须通过电缆连接到外部电源。外部电源可以是IC697电源模块（参见GFK-0717）或其他外部电源。外部电源产生的+5、+12和-12 VDC输出以及5V远程感应通过PSA连接到IC697机架背板。通过PSA提供给背板的最大电流为：+5伏输出18安培，+12伏输出2安培，-12伏输出1安培。PSA监测+5伏输出和来自外部电源的ttl兼容输入电源OK信号（ttl）。输入电源正常信号（TTL）表示外部电源输入电压足以维持系统有序关机的保持时间。PSA还产生两个背板信号，ACFAIL*和SYSRESET*，用于通电/断电序列。外部电源必须提供足够的保持时间（根据ANSI/IEEE STD1014-1987，至少5.05毫秒）以及输入电源正常信号（TTL），以确保断电时系统有序关闭。a44940请勿在通电的情况下拆卸或插入模块。可能发生人身伤害、系统故障和/或设备损坏。警告，即使电源关闭，输入/输出端子板和电源端子板上仍可能存在来自用户现场接线的危险电压。处理电源和输入/输出模块以及与其连接的任何接线时应小心，以防人身伤害。PWR 720模块IC697PWR720标签44A726758–504R01警告电路名称0V端子 建议外部电源电源具有+5V远程感应。
Power adapter module
This power adapter module (PSA) for the feature IC697 I/O system is a single slot module that plugs into a power slot, which is the leftmost slot in the IC697 rack. The PSA module must be cabled to an external power supply. External power supply can be IC697 power module (see GFK-0717) or other external power supply. The+5,+12 and - 12 VDC outputs from the external power supply and the 5V remote sensing are connected to the IC697 rack backplane through the PSA. The maximum current supplied to the backplane through the PSA is:+5V output 18A,+12V output 2A, - 12V output 1A. The PSA monitors the+5V output and ttl compatible input power OK signal (ttl) from the external power supply. The input power normal signal (TTL) indicates that the input voltage of the external power supply is sufficient to maintain an orderly shutdown of the system. PSA also generates two backplane signals, ACFAIL * and SYSRESET *, for power on/power off sequences. The external power supply must provide sufficient holding time (at least 5.05 ms according to ANSI/IEEE STD1014-1987) and input power normal signal (TTL) to ensure that the system shuts down orderly in case of power failure. A44,940 Do not remove or insert the module with power on. Personal injury, system failure and/or equipment damage may occur. Warning: even if the power supply is turned off, there may still be dangerous voltage from the user's field wiring on the input/output terminal board and the power terminal board. Care should be taken when handling power and I/O modules and any wiring connected to them to prevent personal injury.

电源输入电压
当底板上的+5伏输出处于调节状态时，PSA上的LED指示灯亮起，并且来自电源的TTL信号表明电源输入电压足以维持系统有序关闭的保持时间。该TTL信号可以是正逻辑或负逻辑。PSA端子板上的两个端子（JP1和JP0）可用于选择逻辑状态。如果是正逻辑（如果TTL=高，则输入电源正常），则不需要跳线；如果为负逻辑（如果TTL=低，则输入电源正常），则在端子JP1和JP0之间需要跳线。电源适配器的操作此电源适配器模块使用从IC697机架背板上的+5 VDC电源总线接收的+5 V直流电源进行操作。双机架操作单个外部电源可以为两个机架供电。在此应用中，PSA必须安装在第一个机架中。有关此应用程序的详细信息，请参阅适用的可编程控制器安装手册。安装电源适配器是一个插入电源插槽的单插槽模块，该插槽是IC697机架的最左侧插槽。它通过一端连接到电源的电缆连接到外部电源模块。电缆的自由端应具有弹簧铲或环形接线片，这些接线片必须连接到电源适配器端子板上的指定端子。通过打开电源适配器模块上的铰链门可以访问此端子板。电源适配器模块门用右手拇指或指甲抓住门的左上角，轻轻地将门拉向您，即可轻松打开电源适配器门。打开车门时要小心，因为从底部拉动会导致铰链或车门断裂。
Power input voltage
When the+5V output on the backplane is in the regulated state, the LED indicator on the PSA lights up, and the TTL signal from the power supply indicates that the input voltage of the power supply is sufficient to maintain the holding time of the system's orderly shutdown. The TTL signal can be positive logic or negative logic. Two terminals (JP1 and JP0) on the PSA terminal board can be used to select the logic state. If it is positive logic (if TTL=high, the input power supply is normal), jumper is not required; If the logic is negative (if TTL=Low, the input power supply is normal), a jumper is required between terminals JP1 and JP0. Operation of the power adapter This power adapter module operates using+5 V DC power received from the+5 VDC power bus on the IC697 rack backplane. Dual rack operation A single external power supply can power both racks. In this application, the PSA must be installed in the first rack. For more information about this application, refer to the applicable PLC installation manual. The installation power adapter is a single slot module that plugs into the power slot, which is the leftmost slot of the IC697 rack. It is connected to the external power module through a cable connected to the power supply at one end. The free end of the cable shall have spring spades or ring lugs which must be connected to the specified terminals on the power adapter terminal block. This terminal strip can be accessed by opening the hinged door on the power adapter module. The power adapter module door can be easily opened by grasping the upper left corner of the door with your right thumb or fingernail and gently pulling the door toward you. Be careful when opening the door, as pulling from the bottom will cause the hinge or door to break.
