720220 16-Channel General Purpose Module
The Yokogawa 720220 is a 16-channel voltage input module designed for high-density, flexible data acquisition, offering independent range and coupling settings on each channel.
When installed in a ScopeCorder system, it supports expansion up to 128 channels and sampling rates of 10 kS/s with all channels active.
- High-Density Voltage Measurement: Sixteen isolated voltage channels* on a single module provide compact and scalable acquisition. Up to 128 channels possible by installing eight modules in a DL950 or SL2000 system.
- Flexible Configuration: Each channel supports independent range, coupling, scaling, position, zoom, and display settings for precise tuning across multi-point voltage measurements.
- Versatile Sampling Performance: The module provides 200 kS/s when using a single channel and 10 kS/s when using all sixteen channels simultaneously. This allows both faster point measurements and wide system monitoring.
- Strong Noise Rejection: The module provides 86 dB CMRR at 50/60 Hz. A selectable 500 Hz bandwidth limit on each channel helps maintain signal integrity in noisy environments.
- Ideal for Multi-Point System Monitoring: Suitable for measurements up to 42 V (DC+ACpeak) and ideal for battery strings, sensor arrays, slow-speed control signals, and distributed voltage measurements where high channel density and consistent accuracy are important.
*Input channels are isolated from ground. There is no isolation between channels within the input terminal block.
