DANGER Risk of injury caused by hot actuator Hot media flowing through the valve heats up the metal connecting elements on the actuator. ● Do not touch hot surfaces. Engineering SAZ31.00 3-position actuators must have their own specific controller, see "Connection Diagrams". SAZ61.03 Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA. Modulating actuators have an input impedance of 100 kΩ.
