Description
This module provides 8 differential channels, capable of receiving data from sensors outputing Voltage or Current (via use of an external resistor) depending on the device mode selected.
Features
- 16 bit ADC (12-bit mode for fast speed)
- 3000V dc inter module isolation
- Direct measurement of voltage and current
- Can be Configured using simple ASCII Commands
