GENERAL DESCRIPTION
The device TU-E 3188/4 is able to acquire up to 4 digital inputs and to drive up to 8 transistor outputs. The data are transmitted with MODBUS RTU/ASCII
protocol on RS-485 network.
To assure safe operation of the system, the device is equipped with two Watch-Dog timers: in case of alarm, the outputs are forced automatically on the safe
configuration; also, the outputs are protected against over currents and over temperature.
The 2000 Vac galvanic isolation between inputs, outputs, power supply and RS-485 serial line cancels any ground-loop effect noise, allowing the use of the
device in worst ambient conditions.
The TU-E 3188/4 is in compliance to the Directive 2004/108/EC on the electromagnetic compatibility.
The TU-E 3188/4 is housed in a rough self-extinguishing plastic enclosure of 17.5 mm thickness, suitable for EN 50022 standard DIN rail.
COMMUNICATION PROTOCOLS
On the TU-E3000 modules are implemented the following communication protocols:
MODBUS RTU/ASCII Protocol: one of the most used standard communication protocol; it permit to interface the modules of TU-E3000 series directly to the
greater part of PLC and SCADA software available on the market. For communication setting, refer to the User manual.
OPERATING INSTRUCTIONS
Before to install the device,please read carefully the “Installation instructions” section.
If the correct configuration of the device is unknown, could be impossible to establish a communication with the device; connecting the INIT terminal to the
GND terminal, when the devices is power-on, it goes automatically to the default configuration (see the Operating Manual).
Connect the power supply, the serial bus and the I/O signals as shown in the “Wiring” section.
The “PWR” LED, changes its state in function of the working condition of the device: please refer to the "Light signalling" to verify the correct working of the
device.
To make easy the maintenance or the substitution of the device, it is possible the “hot swap” of the terminals.

INSTALLATION INSTRUCTIONS
The device DAT 3188 is suitable to be mounted on DIN rail, in vertical position.
For a correct working and a long life of the device, read the following indications.
DIGITAL INPUT WIRING
In case of the devices are mounted side by side, please leave about 5mm
between in the following situations:
- Temperature in the cabinet higher than 45 °C and high supply voltage
( >27Vdc ).

Avoid to place raceways or other objects which could obstruct the ventilation
slits. It is suggested to avoid that devices are mounted above appliances
generating heat; their ideal place should be in the lower part of the panel.
Avoid to install the devices in a site where vibrations are present.
It is recommended to use shielded cable for connecting signals. The shield must
be connected to an earth wire provided for this purpose. Moreover it is suggested
to avoid routing conductors near power signal cables.
