CURRENT LOOP I/O
Also available: V450 Analog Input Module
- 12 independently isolated, independently programmable channels
- Capable of driving and simulating both controllers and transducers, measuring loop voltages and currents, and simulating faults
- Channel functions include:
- 0-24 mA output using internal power source
- 0-32 mA control with external loop power
- 0-32 mA loop current measurement
- 0-20 V voltage output with current measurement
- Voltage measurement
- Open circuit
- Short circuit
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. An economical measurement-only version is also available. |
