Here are some key features and functions of the 440R-GL2S2P safety relay:

Safety Inputs: The relay has two-input channels that can be used to monitor various safety devices such as emergency stop buttons, safety switches, light curtains, and other safety sensors.

Dual-Channel Configuration: The relay has a dual-channel configuration, which means it requires two input signals to be active and synchronized for the output to switch. This feature helps ensure redundancy and improve the safety of the controlled system.

Feedback Monitoring: The safety relay can monitor the status of external devices and sensors connected to the safety outputs. It provides feedback on the condition of the signals, allowing for additional diagnostics and fault detection.

Safety Outputs: The relay has two normally open, solid-state safety outputs that can be used to control the power to the machine or activate other safety functions. These outputs are designed to switch off quickly in case of a fault or hazardous condition.

Safety Category: The 440R-GL2S2P safety relay is typically used in applications up to Category 4 (per ISO 13849-1) or SIL 3 (per IEC 61508), depending on the specific configuration and usage.
