Important Note

Please compare the original controller’s model, terminal layout, voltage, sensor signal, actuator current, and wiring before ordering. The supplied specifications list the remote variable speed range as “500–7.5Hz”; this has been presented as 500–7,500Hz for consistency with the stated 7.5KHz range. Confirm the exact operating range in your equipment manual. Professional installation is recommended.
