Applications This floor/base mounted contact module with normally closed functionality is ideal for safety-critical applications where fail-safe operation is required, tool-free connections are preferred, and mounting from below or at the base level is necessary. Perfect for emergency stop circuits, safety interlocks, alarm monitoring systems, and applications where the contact needs to be closed in the rest position. The spring-type terminals make it particularly suitable for environments requiring frequent maintenance or reconfiguration.

Mounting & Installation

  • Floor/base mounting design - mounts from below or at base level
  • Snap-on concept allows one-hand installation
  • No special tools required for assembly
  • Compatible with SIRIUS ACT command and signaling devices
  • Alternative mounting option to standard front plate mounting

Floor/Base Mounting Benefits

  • Rear access installation: Ideal when front panel space is limited
  • Protected mounting: Contact module is less exposed than front-mounted variants
  • Space efficient: Allows for more compact front panel designs
  • Maintenance accessibility: Easy access from behind or below the panel
  • Flexible panel design: Enables creative control panel layouts
  • Reduced front panel complexity: Keeps the operator interface clean and simple

Spring-Type Terminal Benefits

  • Tool-free connection: No screwdrivers or special tools required for wire insertion
  • Faster installation: Quick push-in wire connection saves installation time
  • Reliable spring-loaded contact: Consistent clamping force maintains secure connections
  • Maintenance-friendly: Easy wire removal and replacement without tools
  • Vibration resistant: Spring mechanism maintains contact integrity in dynamic environments
  • Wide wire range compatibility: Accommodates various wire gauges
  • Reduced installation errors: Visual confirmation of proper wire insertion

Normally Closed Contact Advantages

  • Fail-safe operation: Contact is closed in rest position, opens when activated
  • Safety applications: Ideal for emergency stop and safety interlock circuits
  • Alarm systems: Perfect for monitoring applications where open circuit indicates fault
  • Power control: Suitable for applications requiring power interruption upon activation
  • Fault detection: Enables detection of broken wires or connection failures
  • Compliance ready: Meets requirements for safety-rated applications

Combined Benefits The unique combination of floor mounting, normally closed contacts, and spring-type terminals makes this module particularly suitable for:

  • Safety-critical floor-mounted applications requiring tool-free maintenance
  • Emergency stop systems with rear panel access requirements
  • Monitoring circuits where quick connection changes are needed
  • Industrial automation requiring fail-safe operation and space efficiency
