GE DS200ACNAG1ADD Pcb电路板
当控制功能超过设定值时，输出继电器改变状态，相应的AUX LED灯亮起，但显示器上没有给出指示。辅助继电器也可编程为kWh、kvarh和kVAh脉冲输出。2.2.6开关输入（可选）安装控制（C）选项后，PQM具有四个可编程开关输入，可用于多种功能。下图显示了开关的内部电路。每个开关输入可以用20个字符的用户定义名称进行编程，并可以选择接受常开或常闭开关。可分配给开关的各种功能列表如下所示，随后是每个功能的描述。关闭报警继电器新需求周期设定点访问选择模拟输出选择模拟输入AUX1继电器AUX2继电器AUX3继电器脉冲输入1脉冲输入2脉冲输入3脉冲输入4清除能量清除需求
When the setpoint is exceeded for a control feature, the output relay changes state and the appropriate AUX LED lights but no indication is given on the display. The auxiliary relays can also be programmed to function as kWh, kvarh, and kVAh pulse outputs. 2.2.6 Switch Inputs (Optional) With the control (C) option installed the PQM has four programmable switch inputs that can be used for numerous functions. The figure below shows the internal circuitry of the switches .Each switch input can be programmed with a 20-character user defined name and can be selected to accept a normally open or normally closed switch. A list of various functions that are assignable to switches is shown below, followed by a description of each function.OFF ALARM RELAY NEW DEMAND PERIOD SETPOINT ACCESS SELECT ANALOG OUTPUT SELECT ANALOG INPUT AUX1 RELAY AUX2 RELAY AUX3 RELAY PULSE INPUT 1 PULSE INPUT 2 PULSE INPUT 3 PULSE INPUT 4 CLEAR ENERGY CLEAR DEMAND
