Cu10, Cu25 RTD Input/Three-Wre Isolated RTD Input (/N1)
Item Specfcatons
Function In addition to the standard input, the MV can also receive Cu10 and Cu25 input.
On the MV1006, MV1012, MV1024, MV2010, MV2020, MV2030, MV2040, and MV2048,
all the RTD input terminals (A, B, and b) are isolated on each channel.
