1 Introduction
Thank you for choosing a Pixsys instrument.
TD240 is a graphical Touch screen HMI, available also with an
integrated PLC. The graphical resources are easily manageable
by TdDesigner, a simple and versatile development environment,
while the PLC logic is managed by PLProg development
environment, which is common to other Pixsys devices .
The waterproof protection of the facade is IP54 and IP30 for the
enclosure.
2 Model identification
There are two versions of the product.
TD240

5 Electrical connections
Although this instrument is designed to resist the most
difficult conditions in industrial environments, it
is good practice to observe the following precautions:
• Distinguish supply line from power line
• Avoid proximity with remote control switches,
electromagnetic contactors, and powerful
motors.
• Avoid placing near power installations, particularly
if phase-controlled
Wiring plan TD240-11AD.

The expansion board is provided with 16 pins for digital I/O. Each
pin can be used as input or output. If used as output, the tension
value generated by the output is also read as input.
