16-channel AC current frequency acquisition module

Analog Input

Input Channels

16 current channels

Input Type

AC current input

Current Range (RMS)

Default 50A (customizable: 1A, 5A, 10A, 20A, 50A, 80A, 100A, 120A, 150A, 200A, 250A)

Customers must specify the range before shipment.

Output Parameters

RMS current

Note: Modules with a T suffix have the function to measure ambient temperature and humidity. See section 1.5 for comparison of different suffixes.

Sampling Rate

For current acquisition: 10 sps per channel, simultaneous refresh

For current and frequency acquisition: 1 sps per channel, simultaneous refresh

Acquisition Accuracy

2‰

Note: When the monitored current is below 100mA, measurement error increases due to the larger error in the current transformer ratio.
