Emparro67 Hybrid:分布式供电新高度

创新的Emparro67 Hybrid 电源是带有许多强大功能的全封装电源:它不仅将电源从控制柜重新定位到工业现场,还可以使用两个集成通道对电流进行监控,实现24VDC负载电路监控,保证了运行的可靠性。IO-Link接口可实现广泛而透明的通信。 The innovative Emparro67 Hybrid power supply is an all-rounder with many powerful features: it not only relocates power supply from the control cabinet to the industrial field, but it also monitors currents using two integrated channels for 24 VDC load circuit monitoring, to ensure high operational reliability. An IO-Link interface permits extensive and transparent communication.

Emparro67 Hybrid 是可满足机械现场所有要求的IP67电源

Emparro67 和Emparro67 Hybrid

Emparro系列IP67电源设备专为柜外应用而设计。 保护所有组件免受机械应力。 紧凑且坚固的金属外壳完全密封,在恶劣的工业环境中免受灰尘,湿气和冷却润滑剂的影响。 其高能效(能量转换率高达93.8%)使设备即使在处于满负荷运行时仍旧保持较低表面温度且可以直接触摸。 这使电源设备成为针对许多不同应用的真正多面手。

IP67 power supply units of the Emparro line are designed for applications outside the control cabinet. All components are protected from mechanical stress. The compact and robust metal housing is fully potted and protected from dirt, humidity and cooling lubricants in the rough industrial field. Their high energy efficiency – up to 93.8 percent of the energy applied is used – allows the units to be touched, even when under full load owing to their low surface temperature. This makes the power supply units a real all-rounder for many different applications.

这种分布式解决方案的最大优势是:从230 VAC到24 VDC的电压转换不再在机柜中进行,而是直接在现场负载附近进行,因此功率损耗保持在了最低水平,能源成本得以降低。同时可以使用较小的控制柜,在某些应用中甚至有可能完全摆脱控制柜。

The great advantage of this decentralized solution: The voltage conversion from 230 VAC to 24 VDC no longer takes place in the cabinet, but directly in the field and thus right at the load. Power loss is kept to a minimum and energy costs are reduced. Smaller cabinets can be used, and in some applications it may even be possible to completely get rid of them.

电子电流监控,确保操作高度可靠性

Electronic current monitoring for high operational reliability

新型Emparro67 Hybrid电源带有两个集成了MICO的通道,可用于监控例如独立的系统组件,传感器,执行器,特别是现场总线模块等的电流。 这样,可以分别监控连接现场总线系统的传感器和模块电压以及执行器电压。 可确保分离性能,对于两路输入电压的通用监视是不可能的,并提供了最大的运行可靠性。 如果执行器电源中断,例如由于短路,过载或电缆断裂,则继续通过传感器和模块电压为现场总线供电。 这意味着故障消息和诊断信息仍然可以发送到PLC。

The new Emparro67 Hybrid power supply has two integrated MICO channels for electronic current monitoring of, for example, separate system components, sensors, actuators, or in particular of fieldbus modules. In this way, both sensor and module voltage and actuator voltage of the connected fieldbus systems can be monitored separately. This guarantees the desired selectivity, which would not be possible with common monitoring of both input voltages, and provides maximum operational reliability. If the actuator supply is interrupted, for example due to short-circuit, overload or cable break, the fieldbus continues to be supplied via the sensor and module voltage. This means that error messages and diagnostic information can still be sent to the PLC.

可以通过设备上的按钮或通过通讯接口将监视两个24 VDC负载电路的Mico通道调整为不同的电流值。 Mico通道的关断功能已获得专利,并应用了“尽可能晚,但在必要时尽早”的原则。一旦达到设定电流值的90%,就会触发预警,从而可在错误发生之前就采取行动。 断开的通道可以通过按下按钮或通过信号来激活。 如果是进行维护,维修人员通过按设备上的按钮断开通道,则只能由维修人员手动将其重新激活。 在这种情况下,在此过程中将禁用远程打开选项。

The Mico channels for monitoring the two 24 VDC load circuits can be adjusted to different current values, either by pressing a button directly on the device or via a communication interface. The tripping process of the Mico channels has been patented and applies the principle of “as late as possible, as early as necessary.” Once a share of 90 percent of the adjusted current value has been reached, an early warning will be triggered that enables steps to be taken before an error occurs. Disconnected channels can be activated at the press of a button or via a signal. If, for reasons of maintenance, a service person disconnects a channel by pressing a button on the device, it can only be reactivated manually by the service person. In this case, the remote switch-on option is deactivated during this process.

广泛的通讯

Extensive communication

Emparro67 Hybrid配备有IO-Link接口(M12连接),可以与 IO-Link 主站作为设备进行通信。 因此,可以在完全联网的智能应用程序中使用Emparro67 Hybrid,以传输全面的诊断数据和操作特性。例如监视设备的使用寿命:Emparro67 Hybrid可提供有关设备状态的精确信息。 如果达到了操作员定义的状态,则可以直接启动订单,并且可以在下一个维护周期内更换设备,而避免额外的检修或停机。 工厂建筑和机械工程行业公司可以使用这种预测性维护功能来开发新的业务。

The Emparro67 Hybrid is equipped with an IO-Link interface (M12 connection) and is able to communicate as a device with a superior IO-Link master. It is thus possible to use the Emparro67 Hybrid in fully-networked intelligent applications transporting comprehensive diagnostic data and operating characteristics. A concrete application is the monitoring of the device's life span: the Emparro67 Hybrid provides precise information on the status of the device. If a status defined by the operator is reached, an order can be initiated directly and the device can be replaced during the next maintenance period without considerable additional efforts or downtimes. Companies in the plant construction and mechanical engineering sector can use such predictive maintenance functions for the development of new business models.
