MVME172-523A工控模块
如果必须作出特殊安排，则可随时提供适合系统的24V DC商用装置。辅助输出这是作为状态输出提供的非安全输出。它在使用PLC功能机器控制和硬接线安全电路作为PLC状态输入的系统中特别有用。其他用途包括保护方案中的诊断和/或驱动状态灯或警报。安全功能不得依赖于此输出。电弧抑制建议所有感应负载使用电弧抑制网络或设备。对于安全电路，抑制器应安装在负载上，而不能安装在触点上。抑制器的类型和额定值将由电源和负载特性决定。注意，抑制器可以增加响应时间，特别是直流线圈两端的抑制器二极管，并且在测量响应时间时应安装到位。控制单元安全输出电源至控制单元执行力时间20ms响应时间控制单元安全输入电源至控制装置重置执行力时间20m s响应时间24接触器监控接触器监控通过标记为MC的两个端子提供。它应用于所有双通道双接触器系统。
如果其中一个接触器未能隔离电源，则垫控制单元将锁定并防止另一个接触器重新通电，直到故障得到纠正。5.8最终传感器垫布局考虑到这些因素后，现在可以检查并最终确定传感器垫布局。考虑机器响应时间是否与初始计算有所不同。在可能的情况下，应在检测区的外侧边缘设置垫子和电线。这简化了安装和更换（如果需要），并且所有布线都受到周边装饰的保护。5.9布线所有系统布线必须防止机械损坏，并适当密封以适应操作环境。提供防水对接接头用于垫子到垫子的连接，并由边缘镶边保护。如果需要在地板上布线，440F-T3230导线导管可以提供适当的保护。其他电线线路应使用导管或线槽。控制单元的密封完整性必须通过使用尺寸正确且紧固的导管配件或电缆压盖保持在IP65。布线实践必须符合EN 60204-1第14条的要求。注意：为了确保110/230V电源的隔离，输入电源必须单独布线，并通过用于输出接线的单独配件或压盖进入控制单元。从控制单元到垫子的电线可以使用导管埋在地板中，或通过边缘装饰件。
If special arrangements must be made, 24V DC commercial devices suitable for the system can be provided at any time. Auxiliary Output This is a non safe output provided as a status output. It is particularly useful in systems that use PLC function machine control and hardwired safety circuits as PLC status inputs. Other uses include diagnostics and/or driving status lights or alarms in the protection scheme. The safety function must not depend on this output. Arc suppression It is recommended that all inductive loads use an arc suppression network or device. For safety circuits, suppressors shall be mounted on the load, not on the contacts. The type and rating of suppressors will be determined by the power supply and load characteristics. Note that the suppressor can increase the response time, especially the suppressor diodes at both ends of the DC coil, and should be installed in place when measuring the response time. The time from the safe output power of the control unit to the execution force of the control unit is 20ms, and the response time is 20ms. The time from the safe input power of the control unit to the reset execution force of the control device is 20ms. The response time is 24. The contactor monitoring is provided through two terminals marked MC. It is applied to all dual channel and dual contactor systems.
If one of the contactors fails to isolate the power supply, the pad control unit will lock and prevent the other contactor from re energizing until the fault is corrected. 5.8 After taking these factors into account, the final sensor pad layout can now be checked and finalized. Consider whether the machine response time is different from the initial calculation. Where possible, mats and wires shall be provided at the outer edge of the detection area. This simplifies installation and replacement, if required, and all wiring is protected by the perimeter trim. 5.9 Wiring All system wiring must be protected from mechanical damage and properly sealed to adapt to the operating environment. Waterproof butt joints shall be provided for the connection of mat to mat, and shall be protected by edge trimming. 440F-T3230 conductor conduit can provide proper protection if wiring is required on the floor. Conduit or trunking shall be used for other wire routes. The sealing integrity of the control unit must be maintained at IP65 by using conduit fittings or cable glands of correct size and fastening. The wiring practice must comply with the requirements of Clause 14 of EN 60204-1. Note: In order to ensure the isolation of 110/230V power supply, the input power supply must be wired separately and enter the control unit through separate fittings or glands for output wiring. The wires from the control unit to the mat can be buried in the floor using conduits or through edge trims.
