Safety Relays

Dual-channel Design Safety Relay
Safety relays are an important link between industrial safety equipment and control systems, ensuring seamless integration and optimal safety performance.
Suitable for industrial sites with high safety requirements, monitoring various signals, including emergency stop signals, safety door switch signals, safety grating signals, two-hand button signals, etc. in addition to safety light curtain signals. The main function is to protect mechanical operators and mechanical equipment exposed to different degrees of danger.
Dual-channel design: Monitor two transistor signals - power off switch, safety light barrier, etc. DADISICK safety relays can also monitoring two NC switch signals with the peripheral circuit.
Self-monitoring and diagnostics: Safety relays continuously monitor internal components, detecting and reporting faults for proactive maintenance.
