Connection module MDPL1 for DEX/P for connecting DEX/P to external systems 4-20mA

Connection module for 4-20mA systems

This connection module, designated MDPL1, is used to integrate DEX/P measuring detectors with external systems utilizing the 4-20mA signal standard. It enables effective connection of GAZEX detectors with the existing measurement infrastructure of other manufacturers.

Functionality and safety

MDPL1 acts as an interface, while simultaneously limiting the power and voltage supplied to the DEX/P detector to safe values compliant with ATEX standards (Pi = 2W, Ui = 15V). This is crucial for maintaining certification and safe operation in potentially explosive atmospheres. The module provides not only compatibility but also protection of the measuring device.

• Fault signaling: A built-in mechanism signals problems with the signal wire, informing about values outside the range of 0.5mA – 21mA. This allows for quick identification and removal of faults.
• Power supply: The module operates on 24V DC, which simplifies integration with most control and measurement systems.
• Durable construction: The metal housing provides mechanical resistance and tightness, guaranteeing reliable operation even in harsh industrial conditions.
• Simple installation: A quick and intuitive connection process minimizes installation time and system downtime.
• One detector per input: The module allows connecting one DEX/P measuring detector to a single measurement input of the system.

Technical specifications

The MDPL1 module is characterized by compact dimensions (66 x 160 x 49 mm), which facilitates its installation in limited space. It has an analog 4-20mA output and an emergency control output, increasing the functionality of the measurement system. It is a solid solution for installers and users looking for a reliable interface between GAZEX detectors and other automation systems.
