The challenge
A safety valve is a component that almost never operates, but when it has to, it must not fail. The controller has to know what state the valve is in, detect a stall, and protect the motor.
What we built
- Motor drive with current measurement, to detect end of travel and stalls.
- Power management and input protection.
- A reliable control interface to the client's automation system.
The result
A controller that operates the valve reliably and reports its state to the control system.
