FF-844 is the new Fieldbus Foundation cable compliance specification. FF-844 includes the electrical requirements of ISA 50.02 and IEC 61158, but it also contains some additional requirements which help you know your cable is the right cable for use in FOUNDATION fieldbus control networks.
Cable certified by the Foundation must be UL ITC and PLTC listed. What does that mean? At a minimum, it means these cables meet important mechanical strength requirements and are UL listed to comply with the National Electric Code.
