Features:

• Intelligent 8-channel period/frequency/RPM measurement
• Ideal for signal conditioning of magnetic speed pickups, flowmeters, and encoders
• High noise immunity ensures accurate measurement in industrial environments
• Internal signal conditioning accepts direct input from common speed sensors
• Register-based 16-bit VME module
• Clean, simple architecture simplifies programming

Description:

The V360 is a single-width, 6U height VME module designed specifically to acquire low frequency inputs from industrial speed sensors. The module can measure frequency and period over a wide dynamic range, and is specifically designed to ensure reliable measurement in high-noise industrial environments.

Differential signal inputs are signal conditioned, filtered and presented to the inputs of a custom gate array chip which manages period and frequency measurement. An on-board microprocessor periodically reads the timer chip, checks and scales data, and loads measured values into a dual-port memory interfaced to the VME bus.

The input signal conditioners can be connected directly to common transducer types, including:

• variable reluctance or hall-effect magnetic speed pickups

• AC line voltage or alternator windings up to 150 volts RMS

• Optical pickups

• Reed-switch or signal-conditioned fuel flow meters

• Contact closures or other special levels
