Application

  • Pulse isolator with safety barrier for the supply of NAMUR sensors installed in the hazardous area.
  • Pulse isolator with safety barrier for the detection of mechanical contacts installed in the hazardous area.
  • One input signal can be used on two separate outputs.
  • A cable error alarm can be detected on a separate output.

Technical characteristics

  • PR5202B1 and 5202B2 have relays with change-over contacts or open NPN collectors available in the safe area.
  • PR5202B4 has 4 SPST relays, which are activated simultaneously two and two, available in the safe area. Each relay can be programmed to the function N.O. or N.C.
  • Inputs, outputs and supply are floating and galvanically separated.
  • 5202B is designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. Up to 84 channels per meter can be mounted.
