Discrete I/O modules
Presentation
Discrete I/O modules in the Modicon M340 offer are standard modules occupying a single
slot on the rack. These modules are equipped with either of the following:
A connector for a screw or spring-type 20-way removable terminal block
One or two 40-way connectors
This wide range of “discrete” I/O can be used to meet whatever requirements arise in terms“discrete” I/O can be used to meet whatever requirements arise in terms I/O can be used to meet whatever requirements arise in terms
of:
Functions, AC or DC I/O, positive or negative logic
Modularity, 8, 16, 32 or 64 channels per module
The inputs receive signals from the sensors and perform the following functions:
Acquisition
Adaptation
Electrical isolation
Filtering
Protection against interference signals
The outputs memorize commands issued by the processor to enable control of the
preactuators via the decoupling and amplification circuits.

Description
BMX DpI/DpO/DRA discrete I/O modules are standard format (1 slot). They have a
case, which ensures IP 20 protection of the electronics, and are locked into position
by a captive screw.
I/O modules connected via 20-way removable terminal block
Rigid body providing support and protection for the electronic card
Module reference marking (a label is also visible on the right-hand side of the
module)
Channel status display block
Connector taking the 20-way removable terminal block for connecting sensors or
preactuators
To be ordered separately:
A BMX FTB 20p0 20-way removable terminal block (identification label supplied
with each I/O module) or a preassembled cordset with a 20-way removable
terminal block at one end and flying leads at the other (see page 2/9).
