Some controllers drive the valve actuators with pulsed signals. This increases the response time. For optimal control, the ambient temperature of the actuator must be < 40°C.Pulse-duration modulationThe actuators STA../00 and STP../00 are supplied without a connecting cable. They can be assembled as per the table "Accessories/connecting cables" on page 4. The product also includes halogen-free cable.Standard connecting cable for all STA.. and STP..
