The relay’s dual-channel inputs and solid-state outputs enhance its reliability and reduce the risk of single-point failures. The AND/OR logic configuration allows for flexible integration into different safety system architectures. This makes it ideal for applications requiring a high degree of customization and adaptability.
Configuring Logic‚ Reset‚ and Timing
The 440R-D22R2 offers versatile configuration options for logic (AND/OR)‚ reset (automatic/manual)‚ and timing functions. These settings allow customization to specific application needs‚ ensuring optimal safety and operational efficiency. Refer to the manual for detailed instructions.
AND/OR Logic Configuration
The 440R-D22R2 safety relay provides flexible AND/OR logic configuration options for its dual-channel inputs‚ IN1 (S12‚ S22) and IN2 (S32‚ S42)‚ along with the single-wire safety input (L12). This versatility allows the relay to be adapted to various safety applications‚ accommodating different sensor types and wiring schemes.
The AND logic configuration requires both input channels to be active or ON for the safety outputs to be enabled. Conversely‚ the OR logic configuration enables the safety outputs if either input channel is active.
These logic settings‚ combined with reset options‚ offer a total of eight possible configurations‚ ensuring adaptability to diverse safety requirements. Proper configuration is essential for achieving the desired safety function and preventing unintended machine operation.

Automatic/Manual Reset Options
The 440R-D22R2 safety relay offers both automatic and manual reset options to suit different safety requirements and operational preferences. The selection between automatic and manual reset significantly impacts how the safety system resumes operation after a fault or safety event.
In automatic reset mode‚ the safety outputs are automatically re-energized once the safety conditions are met‚ such as the removal of the hazard that triggered the safety function. This mode is suitable for applications where immediate resumption of operation is desired and a potential hazard is not present after the safety condition is resolved.
In manual reset mode‚ the safety outputs remain de-energized even after the safety conditions are met. A manual reset action‚ typically pressing a reset button‚ is required to re-energize the safety outputs. This mode is preferred for applications where a deliberate action is needed to confirm the safety of the environment before resuming operation.
The 440R-D22R2 also supports monitored manual reset‚ adding an extra layer of safety.
