GE DS200DTBBG1ABB数字控制卡
基本PQM配有一个输出继电器；控制选项提供三个额外的输出继电器。PQM输出继电器具有C型触点（常开（NO）、常闭（NC）和公共（COM））。在250 V交流电下，每个继电器的触点额定值为5 A电阻和5 A电感。有关其他条件下的触点额定，请参阅第13页第1.3节：规范。接线图显示了未施加控制电源时继电器触点的状态；即当继电器未通电时。继电器触点接线取决于继电器操作在S3：输出继电器设定点组中的编程方式（参见第37页第4.4节：S3输出继电器）报警继电器（端子43/44/45）：选定的报警条件激活报警继电器。可以为每个功能启用或禁用警报，以确保只有所需的条件才会引起警报。
The basic PQM comes equipped with one output relay; the control option supplies three additional output relays. The PQM output relays have form C contacts (normally open (NO), normally closed (NC), and common (COM)). The contact rating for each relay is 5 A resistive and 5 A inductive at 250 V AC. Consult Section 1.3: Specifications on page –13 for contact ratings under other conditions. The wiring diagrams show the state of the relay contacts with no control power applied; that is, when the relays are not energized. Relay contact wiring depends on how the relay operation is programmed in the S3: OUTPUT RELAYS setpoint group (see Section 4.4: S3 Output Relays on page –37). • ALARM RELAY (Terminals 43 / 44 / 45): A selected alarm condition activates the alarm relay. Alarms can be enabled or disabled for each feature to ensure only desired conditions cause an alarm.
