Module function and selection constraints
The 6ES7144-4JF00-0AB0: Diagnostic alarm, overflow/underflow detection, and a group error LED are standard. The module draws 0.7 W from the 24 V DC backplane. Important: the module does not support Cu10 sensors; only Pt and Ni types plus bare resistance ranges are available.
Physical integration and isolation
Isolation between channels and the backplane is type-tested at 707 V DC, keeping common-mode noise within 5 Vpp.
