Datexel Ethernet Digital IO Module 8 Digital Inputs / 8 PNP Outputs DAT 8188

Programmable, PNP Output, Great Quality

The device DAT8188 is a Modbus TCP server unit with 8 digital input channels and 8 PNP outputs.

For the digital inputs are available up to 4 counters 32 bit with measure of frequency up to 300 Hz.

The Ethernet interface allows to read and write in real time the value of device's internal registers.

The built-in Web Server allows the remote visualization and acquisition of the digital inputs state, to drive the digital outputs and access to and configure the main Ethernet parameters via web browser.

The device is also configurable by the software Dev9K, a free IDE developed by DATEXEL.

The device realizes a full electrical isolation between the lines, introducing a valid protection against the effects of all ground loops eventually existing in industrial applications. The LEDs of signaling of Ethernet activity, input and output state and power supply allow a direct monitoring of the system functionality. The connection is made by removable screw-terminals (inputs, outputs and power supply) and RJ45 plug (Ethernet).

The device is housed in a rough self-extinguishing plastic enclosure which, thanks to its thin profile of 22.5 mm only, allows a high density mounting on EN-50022 standard DIN rail.

Series Information

Products designed by Datexel are made keeping all the standards in mind and all products carry the CE mark, and from March 2015 all Slimline products and DAT3000 modules are supposed to carry the UL and CSA mark. Datexel obtained ISO 9001 in 1996 and now has the current standard UNI EN ISO 9001:2000 (issued in 2001). Datexel's signal conditioners also carry the ATEX 94/9/EC approval for safety environments.

In July 2006, there was the conformation of products to the RoHs Directive Standard (2002/95/EC) which enforces restrictions on the use of unsafe substances for the engineering of electric and electronic equipment.

About Datexel:

Founded in 1992 from the commitment and aspiration of several partners as a small provincial company, through the years DATEXEL has become an established reality on Italian and international markets as a manufacturer of electronic equipment for industrial automation and control process.

The range of DATEXEL products includes: Transmitters, signal and temperature Converters (both analogue and digital), galvanic Isolators, signal Splitters, I/O Modules, Trip Amplifiers, Power Supply Units, current loop Isolators, analogue and digital Displays.
