Measuring & threshold control units MDP-1.plus

The MDP-1.plus models are ready to install (wired) sets of the MDP-1.A/T measuring control units, 12 V DC modular power supply unit and a double disconnector, placed in a sealed enclosure (mini switchboard).

Microprocessor-controlled Control Unit type MDP-1.A/T was designed to work with single gas measuring detectors type DEX/P and DG/P or threshold detectors type DEX/F, DEX/A, DG/F and DG.EN.

When preset concentration values are exceeded, the optical alarm, and relay and voltage alarm outputs of the unit are activated (optional: communication via RS485).

Application area

• detection systems of toxic or explosive gases (or oxygen);
• individualized protection of industrial premises or equipment;
• dispersed gas detection systems.

Features

• power supply and control of one detector;
• control of the state of the wired connection to the detector (signals the interruption of any wire);
• configuration of the unit, setting of alarm threshold values (including „window” detection) using the keypad on the front panel;
• optical indication of signal values (LED display) and states of control outputs A1, A2, A3 and detector failure (LED lights);
• alarm outputs 12 V DC (one for each threshold A1 and A2) - power supply of acoustic and optical signaling devices;
• relay outputs (galvanically separated, one for A1, A2, A3 and Failures) - control of fans, contactors, information boards;
• optional: analogue output 4-20 mA or 2-10 V;
• optional: port in RS-485 standard, MODBUS RTU protocol; can be ordered in combination with option with analogue output;
• power supply indicated by an LED;
• removable, screwless terminals, possibility of using single- or multi-strand cable (without crimping sleeves);
• the models are equipped with a standard enclosure/ electrical switchgear, IP54;
• optionally for models equipped with RS-485 port: configuration and visualization of work through dedicated software „DETnet View” - available at https://www.gazex.pl/en/software/.
