There is no Telefast solution with premade cables for the 16-channel M340 discrete I/O modules.
There are three flying lead connection cables available with the terminal block on one end and flying leads on the other.
BMX FTW *01 ->* 3 = 3 meters, 5 = 5 meters and 10 = 10 meters.
The higher density discrete I/O modules (32 and 64 channel) do have a Telefast solution.
The options are listed in the Modicon X80 Discrete Input/Output Modules User Manual.
