Model V220

12-channel VME current loop/process control I/O module

Overview

Features:
  • 12 independently isolated, independently programmable channels
  • Capable of simulating both controllers and transducers, measuring loop voltages and currents, and simulating faults
  • Channel functions include:
    • 0 to 24 mA output using internal power source
    • 0 to 32 mA current control with external loop power
    • 0 to 32 mA loop current measurement
    • 0 to 18 V voltage output with current measurement
    • -5 to +32 volts voltage measurement
    • Open circuit
    • Short circuit
  • Voltage and current measurement in all modes
  • Operates up to 18 volts with internal power, 48 volts with external loop power
  • Protected to ± 50 volts in all modes
  • 0.1% basic accuracy
  • Separate test connector supports in-crate calibration check
  • Clearly labeled dipswitches set VME address; no jumpers, headers, or trimpots
  • Optional built-in self-test (BIST)
Description:

The V220 is ideal for driving and sensing transducers in computer or PLC-based control systems. It can also be used to simulate complex industrial processes to control systems under development and certification.

All units are equipped with channel test relays and a front-panel D9 test connector, allowing channel performance and calibration to be verified without disconnecting field wiring.
