MSI-MD-FB, for local mounting

Productselector

External control of muting processes

If low safety distances are necessary, the MSI-MD-FB muting controller together with the MLC safety light curtains offer a flexible muting solution. It is installed close to the protective device and combines all the necessary connections for sensors, muting indicators and reset buttons. 3 muting operating modes and other detailed functions ensure optimal adaptation to the application. The muting controller works in combination with both MLC safety light curtains and MLD multiple light beam safety devices.

  • Full muting functions in combination with the standard variants of the MLC/MLD series
  • 3 muting operating modes: 2 timing controlled sensors, 2 and 4 sequence controlled sensors
  • Degree of protection IP 67 and durable laser inscription allows for use under harsh ambient conditions
  • Simple configuration via DIP switch, no PC required
  • Only a cable to the switch cabinet with a maximum length of 50 m is necessary
