Control device USln-*, USIw-*, USIOn-*, USIOw-*

USIw-wn©trze.jpg
USIO devices are designed to operate in underground mines attributed to class "a", "b", "c" of methane explosion hazard and to class "A" or "B" of coal dust explosion hazard. USI devices are designed to operate in underground mines attributed to class "a" of methane explosion hazard and to class "A" of coal dust explosion hazard. Spark-safe USI*-* control devices are produced with two types of housing:
  • IP54 class protection (USIn-* and USIw-*),
  • flameproof (USIOn-* and USIOw-*).
They are designed to remote control circuits with contact - especially when the controlled contact is placed in a room exposed to explosion hazard. The contacts of relays are adapted for operation in spark-safe and non-spark-safe circuits. The device controls position of the contact as well as short circuit or breach of line (when controlling a switching contact) and signalize current state of the circuit via LEDs.
USI*-* control device operates in two modes:
  • 1D mode - the system monitors control line with operating contact with a diode,
  • 2 D mode - the system monitors control line with switching contact with two diodes.
