Safety relay module
For small-scale safety control! The easy way to add a safety circuit to the MELSEC-Q Series without using a program.
This module is perfect for small-scale safety control. Despite its simple installation it is highly effective at supporting future expansion and full /partial stop selections.

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
