Additional control units MDPL1
Interface unit for connecting DEX/P detector to other manufacturers’ measurement systems equipped with the standard 4-20 mA current loop with active input
Interface unit MDPL1 is a device used for connecting the DEX/P detector (types: P6…, P4…) manufactured by GAZEX to other manufacturers’ measurement systems with active 4-20 mA current loop.
The device limits the power and the voltage supplied to DEX/P detector head up to the limit values allowed in the ATEX Directive EC-Type Examination Certificate, i.e. Pi = 2 W, Ui = 15 V DC.
Features
- the possibility of connecting one DEX/P head to one measurement system’s input
- 4-20 mA output (passive)
- current loop line error indication (Io ≤ 0,5 mA or Io ≥ 21 mA)
- 24 V DC supply voltage
- watertight, robust metallic enclosure
- very simple and fast connection/installation
