Overview

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 68000-series micro processor 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

Features

• Intelligent 8-channel period/frequency/RPM measurement module
• 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, VXI compliant
• Clean, simple architecture simplifies programming

Specifications

MODEL V360 VME TACHOMETER MODULE

FUNCTION	8-channel pulse period measurement module
CONFORMANCE	Conforms with ANSI/IEEE 1014-1987 VMEbus spec; Meets VXIC VXI spec rev 1.4 for 'B'-size VXI module when used in A16 mode.
PACKAGING	Single-width 6U Eurocard
DEVICE TYPE	16-bit VME register-based slave: A24:A16:D16:D08(EO); implements 32 16-bit registers at switch selectable addresses in the VME 16 or 24 bit addressing spaces.
INPUTS	Eight channels, numbered 0 through 7. Each channel has differential inputs, ground, and +12 volt source. Input impedance is > 60K to ground on differential inputs. Signal level inputs are configurable for standard TTL, open collector, AC generator, and variable reluctance sensor pickups. Onboard signal conditioning includes VME-selectable gains, filtering/integration, and trigger levels to accept 100 millivolt to 150 volt RMS signals up to 100 kilohertz. Inputs will tolerate 1000 volt transients for 50 us.
RANGE	32 bits with 20 ns LSB resolution, approximately 85 seconds maximum period. Transparent interlock logic allows skew-free reading of 32-bit period data.
ACCURACY	± 0.005% +- 1 LSB
RS-232 PORT	9600 baud RS-232 port is provided. This provides for monitoring of module performance and permits channel configuration without requiring host CPU programming. A PC-compatible test/setup program is provided.
CONNECTORS	DB37 female connector for signal inputs and current-limited +12 volt excitation outputs. DB9 female connector for RS-232 serial port. Two BNC signal monitor connectors present analog and digital signal levels of any selected channel.
INDICATORS	Ten LEDs indicate processor heartbeat, VME access, and individual channel trigger activity
