Overview
The V385 is a VME/VXI compatible eight-channel strain-gage signal conditioner applicable to generic bridge-type transducer applications. The V385 adds individual remote-sensed excitation supplies to each channel, increasing its precision over the Model V380's single excitation supply.
Key to the V385's increased precision is a separate remotely-sensed excitation voltage for each channel. Now users can measure up to eight different sensors with different interface cables without the uncertainty of a single sense point for the excitation supply.
The V385's updated firmware accommodates customer requests for faster access to raw sensor data. A firmware version with weighing-specific functions is also available.
Features
- Excites and measures up to eight strain gage load cells.
- Separate, remotely sensed excitation supply for each channel.
- 24-bit ADC per channel
- 100 dB CMRR
- Clean, logical VME bus interface is well suited to PLC-based weighing applications.
- Single-width 6U VME, B-size VXI module.
