Engineering SAS31.. and SAS81.. 3-position actuators must have their own specific controller, see "Conenction Diagrams". SAS61.. 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. SAS61../MO The Modbus converter is dimensioned for analog control at 0…10 V. Note: Keep the analog signal setting on the actuator as is (switch 1 to Off); adjustment not possible.
Disposal WARNING Tensioned return spring Opening the actuator housing can release the tensioned return spring resulting in flying parts that may cause injury. ● Do not open the actuator body. The device is considered electrical and electronic equipment for disposal in terms of the applicable European Directive and may not be disposed of as domestic garbage. · Dispose of the device through channels provided for this purpose. · Comply with all local and currently applicable laws and regulations.
