Addressable control units MDD-L32/T

MDD-L32/T digital visualization and executive units are designed for status visualization of up to 32 detectors, and for control of other devices (e.g. signalling) through contact outputs (4 pieces) and 12 V DC alarm outputs (2 pieces) in Digital Gas Detection System.

Communication with MDD-265/T supervising unit is carried out in industrial standard RS-485 under MODBUS RTU protocol.

Features

• simple and fast status visualization of up to 32 detectors in the Digital Gas Detection System with MDD-256/T supervisor control unit;
• communication in RS-485 standard (MODBUS RTU), galvanically isolated port;
• optical indication of power supply, alarm and emergency states of individual detectors (through the state of 32 sets of 5 LED lights each);
• optical signaling of relay states of control outputs OUT1, OUT2, OUT3, OUT4;
• four standard operating modes of the outputs with division into zones;
• 12 V DC alarm outputs for controlling acoustic and optical signaling; optional: configurable according to individual customer needs (as „OUT5” and „OUT6”);
• in standard: relay outputs (galvanically separated, 4 pieces) to control fans, motors, contactors, information boards or to connect with building/plant automation; optional: configurable according to individual customer needs;
• very simple, intuitive setup of the system with standardized properties and settings (signaling division into two zones, 16 sets of lights and two contact outputs each);
• enclosure adapted for mounting on TS35 rail in standard electrical switchgears;
• configuration of the unit settings via the MDD-256/T control unit – manually using the front panel keypad or via the dedicated „MDD256 View” configuration software, available at https://www.gazex.pl/en/software/.
