MODULA 4

Programmable control unit

MODULA 4 is a detection unit specifically designed to be used in all applications in the area of ​​monitoring and control of areas to be protected from flammable gas leaks or from the presence of toxic gases.

The control unit is equipped with 4 analog inputs 4÷20 mA on board to which standard gas detectors with proportional current output can be connected. The control unit is also equipped with 1 zone relay output for each detector (4 total), 1 general alarm output, and 1 freely programmable auxiliary output.

The zone outputs can be associated with any of the alarm thresholds (Alarm 1, Alarm 2, Alarm 3, Full scale +), or with the failure of the single detector. The alarm output can also be associated with any system alarm threshold. The auxiliary output can be associated with different conditions.

The large backlit graphic display allows you to clearly view the gas concentration measured by the detectors and the alarm thresholds of each detector. The control unit programming takes place with the use of 5 navigation buttons and an intuitive user menu.

Some LEDs are also available on the front for immediate visualization of the condition of the control unit and detectors. The control unit is made in a 9-module DIN rail mounting container.

The mains power supply takes place by means of an external 230/24 Vdc power supply (not included).
