At a Glance

The discrete input/output modules of the Modicon X80 range are standard format modules (occupying one single position), fitted with either:

• one 20-pin terminal block or

• one 40-pin terminal block or

• one or two 40-pin connectors

For modules fitted with 40-pin connector outputs, a series of products known as TELEFAST 2 is available that enables discrete input/output modules to be quickly connected to operational parts.

A wide range of discrete inputs and outputs make it possible to meet the following requirements:

• functional: direct or alternating inputs/outputs, with positive or negative logic

• modularity: 8, 16, 32, or 64 channels per module

Inputs

Inputs receive signals from the sensors and carry out the following functions:

• acquisition

• adaptation

• galvanic insulation

• filtering

• protection against interference

Outputs

Outputs store the orders given by the processor, in order to control pre-actuators via decoupling and amplification circuits.
