Threshold control units MD-1.A/T
Control and power supply units for DEX/F, DG/F or DG.EN threshold gas detectors
Control Unit type MD-1.A/T is designed to work with gas detector types DEX/F, DG/F or DG.EN produced by GAZEX. It is used to build large Gas Detection Systems.
Application scope
- local toxic, oxygen or explosive gas detection systems
- individual protection installations in individual areas
- dispersed gas detection systems
Features
- one gas detector input for DEX/F, DG/F or DG.EN type (power supply with current limitation and connection control)
- status control of the wired connection to the detector (signals interruption of any wire)
- visual alarm states and control outputs (without memory)
- A1, A2 – 12 V DC alarm outputs for the external signaling devices
- separated relay outputs (one for each threshold) for the external signaling devices or fans steering
- case for mounting in standard cabinets (35mm DIN rail)
- outputs functionally compatible with control units outputs type MD-2 (4,8,16) (but no FAILURE output and no remote control input)
- 12 V DC supply (with LED signalization)
