ABB DSAI 146 3BSE007949R1模拟量输入单元
开关A/B/C/D延时：如果开关输入功能分配给报警、AUX1、AUX2或AUX3，则显示此信息。在此消息中输入所需的时间延迟。•kWh/kvarh/kVAh脉冲输出继电器：可为报警或辅助继电器分配五个脉冲输出参数。它们是正kWh、负kWh、正kvarh、负kvarh和kVAh。输入分配每个参数的所需继电器。如果不需要特定输出参数，则选择OFF。•KWh/kvarh/kVAh脉冲输出间隔：输入继电器脉冲发生的适当数量的间隔。脉冲宽度由下文描述的脉冲宽度设置点设置。如果脉冲间隔设置为100kWh，则一个脉冲将指示已累计100kWh。
SWITCH A/B/C/D TIME DELAY: If the switch input function is assigned to ALARM, AUX1, AUX2, or AUX3, this message will be displayed. Enter the required time delay in this message.• kWh / kvarh / kVAh PULSE OUTPUT RELAY: Five pulse output parameters can be assigned to the alarm or auxiliary relays. They are Positive kWh, Negative kWh, Positive kvarh, Negative kvarh, and kVAh. Enter the desired relay to which each parameter is assigned. Select OFF if a particular output parameter is not required. • KWh / kvarh / kVAh PULSE OUTPUT INTERVAL: Enter the interval for the appropriate quantity at which the relay pulse will occur. The pulse width is set by the PULSE WIDTH setpoint described below. If the pulse interval is set to 100 kWh, one pulse will indicate that 100kWh has been accumulated.
