This document provides detailed information for the types of Trusted® input/output (l/0) Cablesavailable within the Companion Slot group. These types of cable provide connection facilitiesbetween the Trusted analogue and digital l/0 modules, and Trusted Field Termination Assemblies(FTAs) or Trusted Versatile Field Termination Assemblies (VFTAs) as required. Cables are alsoavailable with a ‘flying lead’ at one end to allow connection to conditioned terminals.The types of Trusted l/0 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 insulationmust be specified. Length must be specified to the nearest 0.5 m in the format xmx, e.g. 2m0 for acable length of 2.0 m. This detail must be added to the end of the part number. Note that somecable lengths are preferred options and may be easier to obtain; please refer to RockwellAutomation for details. The type of cable insulation forms part of the cable part number and isdenoted by 02 for Low Smoke Zero Halogen (LSzH) or 03 for Ul Certified cable material. 02 is alsoflame retardant to lEC 60332-3 Cat A. When ordering cables, it is recommended that the usersupplies the details as shown in Table 1.
The maximum recommended l/0 cable length is 15 m. Cables longer than this may be specified ifnecessary but may suffer from voltage drop, offset, crosstalk and noise and will present materialshandling problems.
Internal cables are designed for cables where they are terminated in adjacent enclosures. if thecable needs to leave the enclosure environment, the external cable has more protection. Note thatthe ‘external’ cables are not armoured and are not suitable for truly external use and must still betreated with care, These cables will need protection when drawn through a cable route, and shouldalso not be pulled by the connector(s). They should enter cabinets through transit/compressionblocks and cannot be glanded.
