Overview
The V365 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.
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.
Four independent programmable overspeed blocks are provided. Each may be aimed at any selected tach channel, and each is programmable to trip on static or latched overspeed or underspeed conditions. Control provisions include relay polarity and startup override, and provision is made for self-test of the overspeed facilities.
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.
- Incorporates four programmable overspeed/underspeed blocks with independent SPDT relay outputs
Specifications
| FUNCTION | 8-channel pulse period measurement and overspeed 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 tach 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 to100 kilohertz. Inputs will tolerate 1000 volt transients for 50 us. |
