Features

DeviceNet safety I/O terminal block family

The DeviceNet safety I/O-terminal DST-MRD has four inputs for safety signals and four safety relay outputs with up to 2A. Four test pulse outputs ensure crosstalk and short-circuit detection of the inputs.

  • Removable cage-clamp terminals for easy installation
  • 4 inputs for safety signals
  • 4 test pulse outputs to ensure crosstalk and short-circuit detection
  • 4 relay outputs
  • Status LEDs for advanced diagnostics
