Before you order

What to photograph or confirm so the right unit is quoted.

Confirm both AI801 and order number 3BSE020512R1, hardware revision, installed controller and I/O configuration. Match signal range, channel wiring, termination unit and keying. Confirm redundancy or safety requirements against the OEM system documentation; related modules are not automatically interchangeable.
