Free Wire Cables

I/O cables without FTA or VFTA plugs are available for most applications and are designed for

connection to user-designed terminations (terminal blocks, multicore sockets etc.). These have ident

markers on individual cores to show the function of each wire, with the ‘CORE’ text from the tables

below.

The wires are NOT colour coded and core colours will vary between batches or subcontracting

manufacturer. The core colours have not been standardised due to regional supply differences.

Instead, the idents should be used to distinguish between cores. Some cores have identical functions

and are shorted together at both ends (in proper use) as redundant wires. These wires have the same

ident and are interchangeable; there is no need to check which module pin is connected to each core.

The wiring tables for each type of free wire cable are shown below for reference.

TC-202/502/204/504 (40 Channel Input)
