Trusted I/O Companion Slot Cables
Product Overview
This document provides detailed information for the types of Trusted® input/output (I/O) Cables
available within the Companion Slot group. These types of cable provide connection facilities
between the Trusted analogue and digital I/O modules, and Trusted Field Termination Assemblies
(FTAs) or Trusted Versatile Field Termination Assemblies (VFTAs) as required. Cables are also
available with a ‘flying lead’ at one end to allow connection to conditioned terminals.
The types of Trusted I/O Companion Slot Cables currently available are listed in Table 1 on page 4.
The cables are manufactured to user’s requirements; therefore length and type of cable insulation
must be specified. Length must be specified to the nearest 0.5 m in the format xmx, e.g. 2m0 for a
cable length of 2.0 m. This detail must be added to the end of the part number. Note that some
cable lengths are preferred options and may be easier to obtain; please refer to Rockwell
Automation for details. The type of cable insulation forms part of the cable part number and is
denoted by 02 for Low Smoke Zero Halogen (LSZH) or 03 for UL Certified cable material. 02 is also
flame retardant to IEC 60332-3 Cat A. When ordering cables, it is recommended that the user
supplies the details as shown in Table 1.
The maximum recommended I/O cable length is 15 m. Cables longer than this may be specified if
necessary but may suffer from voltage drop, offset, crosstalk and noise and will present materials
handling problems.
Internal cables are designed for cables where they are terminated in adjacent enclosures. If the
cable needs to leave the enclosure environment, the external cable has more protection. Note that
the ‘external’ cables are not armoured and are not suitable for truly external use and must still be
treated with care. These cables will need protection when drawn through a cable route, and should
also not be pulled by the connector(s). They should enter cabinets through transit/compression
blocks and cannot be glanded.
The Companion Slot cables described in this document allow hot-swap modules to be sited in
adjacent slots using a double width chassis socket. For SmartSlot cables, allowing a remote slot to
be assigned as necessary for a hot-swap, refer to Trusted I/O SmartSlot Cables, publication
