⚠️ NOT RECOMMENDED FOR NEW DESIGN — see EM-174
EM-12A DC-motor control unit is designed for industrial and automation applications in the power range of 0–200 W. It offers an economical and easy way to control DC motors with reliable protection features and versatile adjustment options.
The EM-12A can be operated continuously with a single potentiometer for forward / stop / reverse control, or by combining a switch and a potentiometer. It can also be driven by a ±10 V analog signal from an external controller.
The unit includes built-in protection against overload, overcurrent, and overtemperature. These functions enhance durability and ensure safe operation in demanding automation environments.
