Actuators are designed for switching of one (SA3-01B), respectively two (SA3-02B) of various appliances and loads by relay outputs (potentialless contacts).
SA3-01B contains 1 relay with switching potentialless contact with max. load 16 A/4000 VA/AC1.
SA3-02B contains 2 relays with switching potentialless contacts with max. load 8 A/2000 VA/AC1.
Output contacts are separately controllable and addressable.
Thanks to changeover contacts, the SA3-02B actuator can be used to control a 230 V drive (such as blinds, shutters or awnings), whereas by proper bridging of contacts, it is possible to secure locking hardware options while switching on phase two outputs.
Actuators are equipped with a temperature input for connecting an external two-wire temperature sensor TC/TZ (see accessories).
LED on the front panel signalizes the state of each output.
SA3 is normally supplied in the option AgSnO2 contact material.
SA3-01B, SA3-02B are designed for mounting into the installation box.
