Description

Innovative Zygo ZMI-2002 8020-0211 Dual Axis 6U VME High Accuracy Measurement Board

As part of Zygo’s renowned ZMI 2000 series, the Zygo ZMI-2002 8020-0211 builds on the series’ legacy of compact design and robust performance. Its dual-axis capability eliminates the need for multiple single-axis boards, reducing backplane slot usage while maintaining precision. This makes it an ideal choice for industrial control systems (ICS) and distributed control systems (DCS) where space efficiency and measurement accuracy are equally critical. By supporting both VME and ISA interface buses, it ensures compatibility with existing infrastructure, minimizing integration costs for plant operators.

Setup & Service Guidance

Installing the Zygo ZMI-2002 8020-0211 requires careful attention to VME backplane alignment to ensure proper seating and signal integrity. The board should be mounted in a clean, dust-free industrial cabinet with adequate airflow, as sustained operation near maximum temperature limits can affect measurement precision. Grounding procedures must follow VMEbus specifications to minimize electromagnetic interference, particularly when multiple boards are bussed together via the P2 interface.
