The TrolMaster DSR-1 is a high-current relay device station designed to extend TrolMaster control systems to equipment requiring up to 25A at 100–277V. It can be configured through the controller as a temperature, humidity, CO₂, or timer/program output, making one DSR-1 suitable for a variety of high-current equipment such as dehumidifiers, fans, CO₂ solenoids, contactors, and lighting circuits. It connects through the standard TrolMaster RJ12 device bus and includes overload protection, local manual override, and a relay-contact adhesion alarm.

Key Advantage: The DSR-1 provides 25A high-current switching across 100–277V, significantly exceeding the capacity of standard 10A TrolMaster device stations while remaining reconfigurable between temperature, humidity, CO₂, and timer functions. This makes it particularly useful for larger commercial equipment and 208/240/277V installations.
