Functional Features
Monitors emergency stop buttons, safety door switches, and light curtains.
Rich contact resources enable simultaneous control of multiple contactors and status feedback to control systems without additional intermediate relays.
Forcibly guided contacts compliant with EN 50205.
Comprehensive internal protection and fast response for dependable safety logic execution.
Applications
Automated production lines.
Robotic workstations.
Large machining and industrial equipment safety systems.
Material and Structure
Compact modular housing with gold-plated silver tin oxide contacts.
Tool-free quick wiring and replacement design.
Internal diagnostic and contact-reinforced construction.
Operating Principle
The module continuously monitors incoming safety signals from connected safety devices. Upon detecting a hazardous condition, it immediately interrupts the power supply to downstream equipment, executing the safety function with high reliability and response speed.
Installation Requirements
Mount on a 35 mm DIN rail inside a control cabinet.
Wire safety inputs and output contacts according to the terminal assignment.
Ensure correct supply voltage (24 V AC/DC) and secure connections.
Precautions
Confirm the proper safety circuit configuration before commissioning.
Verify contact load ratings against the actual switching duty.
Perform periodic functional testing of the safety function.
Do not exceed switching voltage and current ratings.
