System Q Safety Relay

System Q Safety Relay

The QS90SR2SP safety relay module allows safety I/O to be included in a conventional System Q controller, for when it is not cost effective to specify a dedicated safety controller. The module can be mounted in a conventional System Q rack, or alternatively can be used with a decentralised connection, or on a conventional CC-Link open network. Hence it provides a high degree of flexibility for system design. The QS90 meets all relevant safety certifications such as EN 954 Category 4 and ISO 13849-1/2006 PL e.

System configurations

  • Safety and conventional I/O on the same rack
  • Combine local and decentralized I/O on the same system without complexity
  • Add safety I/O to a standard CC-Link network along with non-safety devices
