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.
