3 Leg Isolated RTD Input (/N2)
Item Specifications
Input terminal All the RTD input terminals (A, B, and b) are isolated on each channel.
Applies to DX2010, DX2020, DX2030, DX2040, and DX2048
Note: On the DX2004 and DX2008 standard models, all the terminals (A, B, and b) are already
isolated on each channel.
