ABB DSDX180A 3BSE018297R1数字输入/输出板
产品选项：PQM可以使用GE Multilin提供的密码在现场升级选项和某些修改。有关使用此功能的详细信息，请咨询工厂。相位CT接线：下表显示了每个设定点设置所需的连接。A、B和C CT连接到相位A、B、C输入。仅A和B CT连接到A和B相。C相输入保持打开。相位C的值由PQM计算。仅A和C CT连接到A和C相。B相输入保持打开。相位B的值由PQM计算。仅CT连接到A相。相位B和C输入保持打开。相位B和C的值由PQM计算。如果选择了A and B ONLY、A and C ONLY或A ONLY连接，则必须使用单独的CT完成中性点感应。
PRODUCT OPTIONS: The PQM can have options and certain modifications upgraded onsite via use of a passcode provided by GE Multilin. Consult the factory for details on the use of this feature.PHASE CT WIRING: The table below indicates the required connection per setpoint setting.A,B, AND C CTs are connected to phase A, B and C inputs. A AND B ONLY CTs are connected to phase A and B only. Phase C input is left open. The value for phase C is calculated by the PQM. A AND C ONLY CTs are connected to phase A and C only. Phase B input is left open. The value for phase B is calculated by the PQM. A ONLY CT is connected to phase A only. Phase B and C inputs are left open. The values for phase B and C are calculated by the PQM.If A AND B ONLY, A AND C ONLY, or A ONLY connection is selected, the neutral sensing must be accomplished with a separate CT.
