Understanding Outputs: Y32 and L11/L12
Y32 provides non-safe status feedback, while L11/L12 enables one-wire safety coupling between relays, utilizing check pulses for secure communication.
Y32 Output – Non-Safe Status Feedback
The Y32 output functions as a non-safe status indicator, primarily intended for feedback to a Programmable Logic Controller (PLC). This allows the PLC to monitor the safety relay’s operational state and display relevant information on a Human-Machine Interface (HMI).
Importantly, Y32 is HIGH when the relay’s OUT LED is LOW, providing a clear inverse signal. This configuration enables the PLC to verify the safety relay is functioning correctly, even in the event of a fault.
It’s crucial to understand that Y32 does not participate in the safety circuit itself; it’s purely for informational purposes and system monitoring.
L11/L12 Outputs – One-Wire Safety Coupling
The L11 and L12 outputs facilitate one-wire safety coupling between multiple 440R-D22R2 safety relays, simplifying wiring and enhancing system flexibility. L11 transmits a safety-related signal with integrated check pulses, ensuring signal integrity. To cascade relays, connect L11 from the first relay to the input of the subsequent relay (using L12).
This method allows for expansion of safety functions across a larger area or more complex machinery. Proper configuration is vital to ensure correct operation and maintain the overall safety integrity of the system.
