Special I/O Cables
Introduction
This document provides detailed information for the TC-800 series of Trusted TM I/O Cables. These
types of cable provide connection facilities between the Trusted TM analogue and digital input/output
modules and field terminations, for cases which do not fit into the other I/O cable series.
The types of TC-800 Trusted TM Cables currently available are listed in Table 1 below.

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 0.5m in the format xmx, e.g. 2m0 for a
cable length of 2.0m. This detail must be added to the end of the part number. The type of cable
insulation forms part of the cable part number and is denoted by 02 for Low Smoke Low Halogen
(LSLH), flame retardant to IEC 60332-3 Cat A. PVC covered cables are not available. 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 15m. 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 can not
be glanded.
