For switching home appliances, e.g. lighting, thermo drivers and sockets.
SA3-01B contains 1 relay with switching potentialless contact with max. load 16A/4000 VA/AC1.
SA3-02B contains 2 relays with switching potentialless contacts with max. load 8A/2000 VA/AC1.
Output contacts are separately controllable and addressable.
Both relay actuator SA3-02B are individually decorated input terminals, and therefore can switch various independent potentials.
Thanks to changeover contacts, the SA3-02B actuator can used to control a 230V 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 front panel signalizes state of each output.
SA3 is normally supplied in the option AgSnO2 contact material. It can be supplied with contact AgNi by request.
SA3-01B, SA3-02B are designed for mounting into the installation box
Temperature measuring: Yes, input for external thermo sensor TC, TZ
