Frequently Asked Questions about 440R-GL2S2T
Question: What is the purpose of the 440R-GL2S2T safety relay?
Date Update:05/06/2025
Answer:

The 440R-GL2S2T is designed to control and monitor guard locking devices to prevent access to hazardous areas during machine operation. It enhances personnel safety by ensuring access doors or gates remain locked until it is safe to enter. The device can also monitor safety switch statuses and enforce stop logic based on configurable delay settings. It is widely used in machinery safety systems for applications requiring controlled access. This helps meet safety standards such as ISO 13849-1 and IEC 62061.

Question: What power supply does the 440R-GL2S2T require?
Date Update:05/06/2025
Answer:

The device operates on a 24V DC power supply. This voltage is standard for industrial control circuits, ensuring compatibility with most safety systems. The power supply must be capable of supporting the relay’s internal electronics and output load. Proper circuit protection, such as fusing, is recommended on the input side. Using a regulated power source helps maintain reliable operation.

Question: Does the 440R-GL2S2T support removable terminals?
Date Update:05/06/2025
Answer:

Yes, the relay is equipped with removable terminals. This facilitates easy replacement and simplifies maintenance without rewiring. Removable terminals allow technicians to swap out the relay while retaining existing connections. This feature reduces downtime and supports modular panel design. It is especially useful in large control cabinets where accessibility is limited.

Question: What is the current rating for the safety outputs?
Date Update:05/06/2025
Answer:

The immediate safety outputs are rated at 0.5 A each, while the delayed safety outputs are rated at 300 mA. These ratings are sufficient for controlling relays or safety contactors that disconnect hazardous energy. Overcurrent protection should be used to ensure circuit integrity. Solid-state outputs ensure fast switching and extended service life. Load capacity must be considered during system design.

Question: Is the 440R-GL2S2T still in production?
Date Update:05/06/2025
Answer:

As of now, the 440R-GL2S2T appears to still be in production and supported by Rockwell Automation. However, customers should always consult the official Rockwell Automation lifecycle status or their distributor for the most current availability. If the device becomes obsolete, migration to a newer model or GuardLink-compatible device may be advised. Proper planning ensures continuity in safety system functionality.
