Modular TBX modules (IP20) : the base units

General

The modular modules are composed of a base unit and an optional extension. The base unit is composed of the following elements:

a TSX LEP ••• (1) communication module which enables communication with the PLC via the Fipio bus,
a base unit (2) with discrete and/or analog inputs and/or outputs,
a removable terminal block (3) for direct connection of the sensors and/or preactuators to the I/O. The necessary power supplies are also wired to the terminal block.
A connection cable (4) for linking the extension module to the communication module.

The following diagram shows the base unit of a modular TBX module.

The TBX BLP 01 connector enables the module to be connected to the Fipio bus.

Physical description

The base units are assembled with a TBX LEP ••• communication module to form a basic module, or with a TBX CBS 010 assembly to form an extension module. Sensors can be connected directly to the inputs, and preactuators to the outputs and the power supplies, by means of the screw terminal.
