1.4. Security
Attention
Switch off devices before connecting them.
ESD (Electrostatic discharge)
Modules have electronic components that can be damaged by.
electrostatic discharge. Be sure to be connected to ground when
handle the devices.
The instrument has no power switch and no internal fuse, but it powers on
immediately after connecting a correct power supply input (check the power supply
value on the instrument label). Keep the power supply line as short as possible and
keep it separate from other power lines.
For security reasons it is necessary to have a 2 section power switch with a fuse near
the instrument and easily replaceable.
Avoid the presence of other power actuators in the same control panel, high humidity,
excessive heat and corrosive gas.
Instruments must have a power supply from security transformers or SELV
transformers.

4.2. Power supply
4.2.1. Isolation
Device has no galvanic isolation between input, output and power supply.
4.2.2. System power supply
TPAC1008 has a 24VDC (-15% +20 %) according to the scheme in the figure.
System is protected against reverse power supply.
As shown in the figure, the digital outputs must have a separate power supply respect
the main power supply of the instrument.
4.2.3. Digital output power supply
TPAC1008 digital outputs must have a separate power supply respect the main power
supply of the instrument to avoid consequences on control system due to I/O
problems.
4.2.4. Fuse
System has no internal fuse , so is suggested the use of an external 1A fuse for the
panel power supply, and an external 3A delayed fuse for the I/O power supply.
Figure 8
Attention
A wrong value for the power supply can cause a damage to the
device.

4.3. Digital input/output wiring
The digital I/Os are PNP type, the wiring must follow the scheme below.
Figure 9
Each digital output can source a 500mA max, and the total current can be lower than
2A.
4.4. Analogue input wiring
By means of the PLC program the TPAC1008 can be configured to connect several
analogue input type. Configuration is done by the setup of a system variable in the
PLC program. Configuration can be set up and modified in any moment.
Configuring input as thermocouple it is possible to connect up to 4 of the following
type:
J (0°C – 600°C),
K(0°C – 1200°C)
T (0°C – 400°C)

Cable type
Cable between TPAC1008 and CANopen slave must be a shielded twisted pair, and
to avoid external disturbances the shield must be connected to both 0V of the
communicating systems. The cable length is a function of the baud rate as follows.
