  • ESM-BA.. Usage up to category 4 according to EN ISO 13849-1
  • LED status indicators
  • 1-channel or 2-channel control
  • 2 redundant safety contacts
  • Short circuit and earth fault/ground fault monitoring
  • Plug-in connection terminals
Relay outputsThe outputs are electrically decoupled and of redundant design. Connection optionsBy using suitable wiring the following functions can be selected:
  • Relay start with automatic start or a start button
  • Monitoring of downstream relays or contactors
  • Simultaneity monitoring to monitor safety components over time
  • Relay start using a monitored start button
  • Short circuit monitoring to detect short circuits between the connection cables and to shut down the outputs or prevent relay starting if necessary
  • Earth fault/ground fault monitoring to detect short circuits between the connection cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.
Important:Depending on the device in question, a connection kit will be required.
