? Tachometer module is not used alone or as a component for speed control or overspeed protection system. ? Tachometer module does not provide redundant protection and response speed speed control or overspeed protection system. ? Analog output ratio is used only for data collection, chart recorder or displayed. In addition, the speed warning set point for notification purposes only. ? The magnetic sensor does not use reverse option, Bentley, because these sensors do not provide a clear edge to the detection circuit at low speed, which can cause erratic reversal instructions. ? The magnetic sensor is not recommended zero speed option, communications gateway module, because these sensors do not provide a clear edge to the detection circuit at low speed. Features compared to conventional rack systems provide a cost even more economical? Continuous online protection via optional Modbus Gateway, Bentley display device can be a rich set of static variables, alarm status and event list data digitization connected to the distributed control system (DCS), programmable logic controllers (PLC), Supervisory Control and Data Acquisition (SCADA) systems, as well as System 1 * optimization and diagnostic software with the use of transmitter equipment protection compared to the way the system Highly reliable, greatly enhancing the protection with a common monitoring system in 3500 and 3300 of proven and reliable circuit design automation equipment Empire | Bentley Systems Module | Bentley Empire by the Shenyang Automation Equipment Co., Ltd. provided.
