Category Specification Details / Notes
Model VCII-10-230
Applicable System Yokogawa MV2000 Data Acquisition Station Must be installed in an MV2000 mainframe.
Input Channels 1 channel per module
Input Signal Voltage Input Current Input (via external sensor)
Input Range (Voltage) AC/DC 300 V max. Selectable ranges within the max limit (e.g., 150V, 300V).
Input Impedance Approx. 2 MΩ (for voltage measurement)
Current Sensor Input Accepts voltage output from external current sensors (e.g., Current Transformers - CTs, shunts). Example: 0.333 V input corresponds to a rated primary current.
Output Signal ±1 V DC (Full-scale) Standardized output to the MV2000 mainframe.
Isolation Voltage 2000 V AC (between input and output) Critical for safety and noise rejection.
Frequency Bandwidth DC to 5 kHz Suitable for power line frequencies (50/60 Hz) and harmonics.
Basic Accuracy ±0.1 % of F.S. (for DC voltage) Accuracy varies depending on the measured signal type (AC/DC, V/A).
Power Supply Supplied by the MV2000 mainframe.
