Our Single-function and Specialty Relays are designed to provide basic and advanced safety functions such as time delays and speed monitoring. They are also designed to be used in specific applications such as two-hand control, muting, and the control of pressure-sensitive safety mats and edges.
Our MSR100 Single-function Safety Relays support a wide variety of input devices and output configurations. These relays are ideal for relatively small safety applications and single zone control and available in electromechanical version, or solid-state models for applications involving high cycle rates. Rockwell Automation announces that as of December 2019, a small number of legacy safety relays in the MSR portfolio will be discontinued and will no longer be for sale. Recommended migration safety relays are from both the MSR and GSR families.
Our Two-hand Control Monitoring Safety Relays detect faults in two-hand controls, wiring, and contactors safety circuits. These relays provide switching action as an intermediate relay. They are designed for use with mechanical and capacitive two-hand control units.
Our Speed Monitoring Safety Relays are designed for motion applications that require interaction by personnel during operation.
Our Stop Motion Monitors detect when hazardous motion has ceased, then sends a signal to unlock guard-locking devices. Rockwell Automation announces that as of December 2017, several Minotaur Safety Relays will be discontinued and no longer for sale. Customers are encouraged to migrate to our Guardmaster® Safety Relays.
Our Back Electro-magnetic Field (EMF) monitoring units interface with single- or three-phase induction motors to measure the drive voltage and the back EMF of the motor.
Muting Light Curtain Monitoring Relays allow the automatic temporary suspension of the safety function if certain conditions are met. In material handling applications, material is allowed to pass through the protective field without shutting down the machine. In addition to muting, these modules monitor up to three light curtains with presence sensing device initiation (PSDI).
Our MatGuard™ Control Unit monitors all of the mats that are connected together to form a safeguarded zone. The safeguarded zone can be up to a total of 100 m and made from any number of mats. The controller interfaces with the control circuit of the machine and includes two safety relays to help provide control redundancy.
Our Bulletin 440F Safedge™ Controllers operate with our Bulletin 440F Safedge Safety Edge Profiles. The controllers continuously monitor the profile for actuation, and they generate an output signal when the profile is depressed.
Our Sipha Control Units monitor and control Sipha non-contact safety sensors. For high-risk applications, the control unit is used with a single Sipha sensor to give a high-integrity system. For other applications, multiple sensors (including mechanical switches) can be connected to a single Sipha control unit.
