RadiSys PBA自动化控制模块

产品详细资料
固态跳闸输出还提供了高速固态（SCR）输出。此输出适用于需要对通信信道进行键控的应用程序。3.2.14模拟输出745提供7个模拟输出通道，其满量程范围可设置为以下范围之一：0至1 mA；0至5毫安；0至10毫安；0至20毫安；和4至20mA。每个模拟输出通道都可以编程为表示继电器测量的参数之一。有关详细信息，请参阅第5-43页的模拟输出1至7。如典型接线图所示，模拟输出信号源自端子A6至A12，并共享A5作为公共回路。输出信号是内部隔离的，并允许连接到处于不同接地电位的设备。每个模拟输出端子被箝位在接地36V以内。为了大限度地减少噪音的影响，应使用屏蔽电缆进行外部连接，并且仅应将屏蔽的一端接地。如果需要电压输出，则必须在外部测量设备的输入端连接负载电阻器。忽略输入阻抗，负载电阻为：如果0至1 mA输出通道需要5 V满量程输出，则RLOAD=5 V/0.001 a=5 KΩ。类似地，对于0至5 mA通道，该电阻器将为1 KΩ；对于0至10 mA通道，此电阻器为500Ω；对于4到20mA通道，该电阻为250Ω。
Solid State Trip Output A high-speed solid state (SCR) output is also provided. This output is intended for applications where it is necessary to key a communications channel. 3.2.14 Analog Outputs The 745 provides 7 analog output channels whose full scale range can be set to one of the following ranges: 0 to 1 mA; 0 to 5 mA; 0 to 10 mA; 0 to 20 mA; and 4 to 20 mA. Each analog output channel can be programmed to represent one of the parameters measured by the relay. For details, see Analog Outputs 1 to 7 on page 5–43. As shown in the typical wiring diagram, the analog output signals originate from Terminals A6 to A12 and share A5 as a common return. Output signals are internally isolated and allow connection to devices which sit at a different ground potential. Each analog output terminal is clamped to within 36 V of ground. To minimize the effects of noise, external connections should be made with shielded cable and only one end of the shield should be grounded. If a voltage output is required, a burden resistor must be connected at the input of the external measuring device. Ignoring the input impedance, the burden resistance is:If a 5 V full scale output is required with a 0 to 1 mA output channel, RLOAD = 5 V / 0.001 A = 5 KΩ. Similarly, for a 0 to 5 mA channel this resistor would be 1 KΩ; for a 0 to 10 mA channel, this resistor would be 500 Ω; and for a 4 to 20 mA channel this resistor would be 250 Ω.
