ReLy series safety relays for OSSD and EMSS devices from SICK

Finding the right safety relay can be a challenge given the complex design and operation of safety devices.

With the new ReLy safety relay series, the selection process is noticeably easier. The relay label already  indicates which devices are intended to be connected to it. 

RLY3-OSSD (Output Signal Switching Device)

RLY3-OSSD relays operate in tandem with safety devices that provide/interrupt signal at digital outputs 

Such devices are:  

• Safety light curtains, optical and inductive safety sensors
• Safety Laser Scanners, Radars and Cameras
• Security locks with digital outputs and other devices with digital outputs 

RLY3-EMSS (Electrical Mechanical Safety Switch) 

RLY3-EMSS relays operate in tandem with safety devices that closes/opens mechanical contacts 

Such devices are:  

• Safety limit switches, stop buttons and magnetic proximity sensors
• Security locks and other devices with mechanical contacts

With ReLy series relays you get:

• Performance level PL e 
• Relay responce  time  10 ms 
• 2 safety inputs  
• Manual/auto  reset 
• Led status indication 
• Compact device  (18 mm width)
