Remote 4 digital inputs, and 4 relay output module DAT3130 Output RS485.


The isolated 4 digital inputs, and 4 relay output module DAT3130 is a Din Rail mount I/O Module. The input is 4 digital inputs and the output is 4 Relays.

The DAT3130 is controlled by the MODBUS RTU/ASCII protocol on RS-485 network.

The DAT3130 is equipped with two Watch-Dog timers. In case of alarm, the outputs are forced automatically to a fail safe condition. The digital outputs can also be used as trip alarms of the input analog signal enabling local control.

The DAT3130 is isolated between the power supply and the input/output to 2000V, eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.

The DAT3130 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.

The DAT3130 is housed in a plastic enclosure of 17.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.


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.


On the DAT3000 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 DAT3000 series directly to the
greater part of PLC and SCADA software available on the market. For communication setting, refer to the User manual.




The device DAT 3130 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.

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.
