Enhanced ZIU 2Analogues I/O PSU DIN Rail
The Zenith surface interface unit (ZIU) for E-Series gauges provides power to and decodes communication from the downhole sensor. The latest ZIU, with comprehensive firmware update, ensures reliable real-time data acquisition supported by enhanced noise filtering for superior data integrity.
Configurable Modbus mapping enables the user to select which parameters are output to SCADA or VSD HMI, and accelerated speed of acquisition delivers data within 60 seconds of pump start-up.
System compatibility has also been extended to allow use with the latest downhole sensor technologies, including sensors for high-speed ESP systems, supporting optimized ESP system performance and remote production operations.
The ZIU contains onboard data logging and multiple supervisory control and data acquisition (SCADA) connections including RS232, RS485 and Modbus TCP to allow maximum flexibility when connecting to modern variable speed drives.
For legacy variable speed drives, the ZIU contains a pair of high-resolution analogue current inputs and outputs. The ZIU also provides relay contacts to allow automated shutdown of variable speed drives, protecting lift systems and ensuring well integrity. The ZIU must be mounted within a cabinet.
