The Schmersal AZR 311 TL is a safety control module designed to operate on 24 VAC/DC. It features flexible input options, allowing for either two normally closed contacts or one normally closed contact, depending on your setup. On the output side, the module provides four enabling paths, including one with an adjustable delay ranging from 0 to 30 seconds. This product has been replaced by the SRB-E-301ST model, but it remains a reliable option in many applications. You can find the AZR 311 TL available through BSP Automation, offering support for your safety control needs.
