Maintaining strict process control is critical in environments where product safety directly impacts human health. In pharmaceutical manufacturing\u2014especially for products introduced into sensitive areas like the human eye\u2014compliance with FDA regulations is non-negotiable. To meet these rigorous standards, a pharmaceutical company partnered with Johnson Controls<\/a> to implement a reliable timing solution across their production facility: the DC-25T-DN-BCD countdown timer.<\/a><\/p>\n\n\n\n

Supporting FDA-Compliant Airlock Procedures<\/h4>\n\n\n\n

In this application, the timers were installed at each access point leading into the sterile production area. These access points function as airlock chambers, where incoming materials\u2014specifically ingredient drums\u2014must undergo a sanitization process before entering the controlled environment.<\/p>\n\n\n\n

Each airlock uses a sterilizing agent to eliminate bacteria and other contaminants. To ensure effectiveness, the drums must remain inside the chamber for a precise, predetermined duration. The DC-25T-DN-BCD timer<\/a> enforces this process by counting down the required dwell time and restricting access during the cycle.<\/p>\n\n\n\n

Using an integrated relay, the timer can lock out entry to the airlock until the countdown is complete. This prevents premature access and helps guarantee that every batch meets the required sterilization standards. At a glance, operators can clearly see how much time remains before it is safe to proceed, improving both compliance and workflow efficiency.<\/p>\n\n\n\n

Simple, Reliable Operation for Demanding Environments<\/h4>\n\n\n\n

What sets the DC-25T-DN-BCD<\/a> apart is its straightforward and durable control interface. The unit is operated through three external terminals connected to an internal opto-isolated board, ensuring dependable performance in industrial settings.<\/p>\n\n\n\n
