SmartGuard 600 Safety Controllers with Safety

Our Bulletin 1752 SmartGuard™ 600 Controllers with Safety feature 16 safety-rated inputs, 8 safety-rated outputs, 4 pulse test sources and an optional EtherNet/IP™ port. Each controller also includes a DeviceNet™ connection to support both standard CIP and CIP safety. You can configure and program on EtherNet/IP, on DeviceNet or through the built-in USB port. These small, cost-effective intelligent controllers can perform safety interlocking between GuardLogix® or other SmartGuard safety controllers.

  • Ideal for mid-level safety applications that are too complex for safety relays, yet too simple for full-sized safety PLCs
  • Integrates with Guard I/O™ modules to expand the number of safety devices you can control
  • Provides data to standard PLCs and HMIs through EtherNet/IP™ or DeviceNet™
  • Lets you configure and program through RSNetWorx™ for DeviceNet software (required for EtherNet/IP controller)

The SmartGuard 600 controller bridges the gap between a safety relay system and a safety PLC. It is ideally sized for applications that cannot be solved with safety relays, or are very cumbersome to solve with relays, but are not complex enough for a traditional safety PLC like a GuardLogix® or GuardPLC™ controller.

Use the SmartGuard™ 600 controller in safety applications including:

  • E-Stop
  • Light Curtain
  • Safety Gate
  • Two Hand Control
  • Multi-zone Control
  • Perimeter Guarding
