Details

Advanced features

  • Configuration and monitoring by way of detachable display front (PR 4501).
  • Selection of direct or inverted function for each channel via PR 4501.
  • Advanced monitoring of internal communication and stored data.
  • Optional redundant supply via power rail and/ or separate supply.
  • SIL 2 functionality is optional and must be activated in a menu point.

 

Application

  • 9202B can be mounted in the safe area or in zone 2 / Cl. 1 div. 2 and receive signals from zone 0, 1, 2 and zone 20, 21, 22 including mining / Class I/II/III, Div. 1, Gr. A-G.
  • Pulse isolator for transmission of signals to the safe area from NAMUR sensors and mechanical switches installed in the hazardous area.
  • Monitoring of error events and cable breakage via the individual status relay and/or a collective electronic signal via the power rail.
  • The 9202B has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.

 

Technical characteristics

  • 1 green and 2 yellow/red front LEDs indicate operation status and malfunction.
  • 2.6 kVAC galvanic isolation between input, output and supply.

 

Mounting

  • The devices can be mounted vertically or horizontally without distance between neighbouring units.
