When its input is activated, the output state changes after a user-defined interval, enabling sequencing, interlocks, and startup delays in industrial automation applications. As part of ABB’s timer-relay lineup, the TDR4B12 is designed for integration into standard control panels and logic circuits where repeatable timing behavior is required. The model designation indicates a specific variant within the TDR range, with timing characteristics determined by the installation configuration and documented in ABB specifications. Typical use cases include coordinating multi-step machine operations, delaying a downstream signal to ensure safe ramping of actuators, and creating dwell times to prevent premature activations in automation sequences.\u003c\/p\u003e\u003c\/div\u003e","brand":"ASEA","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660255559982,"sku":null,"price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_facffc1d-ce79-4952-a891-eedd31a6f45f.jpg?v=1769535213","url":"https:\/\/plgautomation.com\/products\/asea-brown-boveri-tdr4b12-time-delay-relay-module","provider":"PLG Automation ","version":"1.0","type":"link"}
