Introduction
Thank you for having chosen a instrument. Model TD320
is a graphical touch screen terminal with an integrated PLC
adapted for the supervision and control of systems where the
participation of an operator (HMI) is necessary. The graphical
resources a
re easily manageable from TdDesigner, a simple and
versatile development environment, while the logic relative to the
PLC is managed from the PLProg development environment,
which is common to other devices (PL250, TCT500, etc).
The waterproof prote
ction of the facade is IP54 and IP30 for the
container.
Model identification
Only one version of the terminal TD320 is available, in low
voltage, AC or DC. This is indicated in the model identification.

3 Electrical connections
Although this instrument is designed to resist the most
difficult conditions pres
ent in industrial environments, it
is good practice to observe the following precautions:
•
Distinguish the line bringing live current from those
of voltage
• Avoid the vicinity of groups of t
elecommand circuit
breakers, electromagnetic contacts, and high-
power motors.
•
In particular, avoid the vicinity of power installations
used to control phase.

3.2 Serial ports of communication
TD320 terminal communication with other devices is possible
through serial connection with RS485, RS232 and RS422.
The electrical signals are available in two connectors present at
the back of the terminal: post DB9 and post DB25.

A cable is available (code art. 1620.00.057, optional), that from
connector DB25 provides COM1 in RS485 for a generic
connection with other devices (for details regarding the
communication protocols, consult other documentation).
