SICK FX3 Series Safety Controller, 96 Safety Inputs, 48 Safety Outputs, 24V dc

SICK FX3 Series Safety Controller, 96 Safety Inputs, 48 Safety Outputs - FX3-CPU000000

This safety controller is a compact, DIN-rail mounted device designed to supervise and manage machine safety functions within industrial automation systems. It operates on a 24V supply and integrates with a programmable safety system to process high-density safety I/O for complex machinery. The unit suits environments requiring category 4 safety performance and supports configuration and diagnostics via an RS-232 interface.

Features & Benefits

• 96 safety inputs enabling extensive sensor coverage for large machines
  48 safety outputs providing numerous controlled stop or safe-state actions
  Category 4 performance delivering the highest architectural safety level
  24V DC operation with 4A supply-current limitation ensuring predictable power design
  Spring-terminal connections allowing secure, tool-free wiring retention

**Applications**

• Suitable for safeguarding multi-axis robotic workcells with many sensors
  Ideal for central safety logic in automated production lines
  Used with safety gate and light curtain networks requiring many inputs
  Can be used for coordinated emergency-stop handling across plant zones

What environmental conditions can it tolerate in operation?

It is specified for operation between −25°C to +55°C and for non-condensing humidity of 10%–95% while housed in an IP20 enclosure.

How is configuration and offline access achieved?

Configuration and diagnostics are provided through an RS-232 M8 female connector, 4-pin Interface for connection to programming tools.

What mechanical mounting and form factor should planners allow for?

The unit mounts to a standard DIN rail and has a narrow module width suitable for Compact control cabinets.

How is system configuration preserved and powered within the safety system?

System configuration and central supply functions require a separately ordered system plug which also services system-level storage and power distribution.

What protection class and electrical categories are relevant for installation planning?

The device conforms to protection class III and overvoltage category II, with switch-on times up to 18s to consider during power sequencing.

Notes

The system memory plug (FX3-MPL) is sold separately
