The VMIVME-2540-200000 is a VMEbus intelligent counter and controller (ICC) module designed for high-precision digital measurement, timing, and signal generation applications. It operates as a VMEbus slave I/O module with an onboard CPU that autonomously executes measurement and control functions once configured by the host system. The VMIVME-2540-200000 is widely used in industrial test, automation, and scientific instrumentation systems requiring accurate event timing and motion measurement.
The VMIVME-2540-200000 supports a wide range of measurement functions, including event counting (up to billions of events), frequency measurement (from ultra-low Hz ranges up to 2.5 MHz), period and pulse-width measurement, and quadrature position measurement. It also supports both integer and floating-point data formats (IEEE 754 32-bit), enabling high-resolution data acquisition and compatibility with host processing systems. Its architecture allows continuous measurement modes, reducing host CPU load during real-time operation.
In addition to measurement capabilities, the VMIVME-2540-200000 provides advanced signal generation functions, including programmable pulse trains, square wave generation, frequency division, and quadrature position control outputs. It supports up to 24 control/measurement interfaces, RS-422 differential signaling, and selectable single-ended TTL inputs. The module includes an onboard 15 MHz 68HC000 CPU and a VMEbus interface supporting A32/A24/D32/D16/D8 addressing modes, ensuring compatibility with standard VMEbus systems.
