To simplify wiring, the following accessories for wiring IP20 distributed I/O modules are proposed:
-
A grounding strip connected to ground by the terminal, which enables all the protective screening for sensors and/or preactuators to be connected to the local ground.
This accessory is sold in lots of 5, reference TBX GND 015.
The quick installation of this strip, (fixed to terminals 2 and 40 on the terminal block) means that, although it is joined to the main terminal block, an additional connection level is formed. The assembly can still be removed.
In addition, a laterally fixed terminal is used to connect the local ground and the metallic parts of the product in order to provide permanent protection of the base units.
-
An inter-terminal connecting comb is used to connect together several terminals at the same voltage.
This accessory is sold in lots of 5, reference TBX RV 015.
They are designed so that 2 combs may be used in the same connection space, one on top of the other. They are perforated so they can be cut to the correct length by the user, and can be used for 2 to 9 terminals.
Insulation between the two combs installed one on top of the other is 2000 V AC.
The following drawing shows the wiring accessories for TBX IP20 modules.
The following table provides the various wiring accessory elements for TBX IP20 modules.

Input and transistor output simulators
Two 8 channel simulators are proposed to enable debugging and maintenance of distributed I/O modules:
