The D5030D enables the acquisition of a signal from a dry contact (SOBA EX) or a proximity sensor installed in a hazardous zone (Zone 0 / Div. 1), electrically isolates it, and faithfully reproduces its state via a relay in a safe zone.
In the context of an application with a SOBA EX dry contact level regulator, the D5030D plays a critical role: it ensures secure transmission of the level signal to the control system while meeting ATEX requirements. It guarantees a reliable interface between field equipment in explosive zones and the installation in safe zones.
Thanks to its dual-channel configuration, the D5030D offers great flexibility. It allows repeating two separate inputs to simultaneously manage multiple signals, or duplicating the same input to two outputs to supply different systems. The second output can also be dedicated to fault signaling (open line or short circuit), enhancing installation safety and diagnostics.
The D5030D is part of the intrinsically safe interface range, specially designed for high-risk industrial environments such as chemical, petroleum or gas industries, where signal transmission reliability and safety are essential.
