KNX/EIB ABB Schaltaktor

Hi,

What is the difference between an ABB Schaltaktor SA/S family and the ABB Schaltaktor AT/S family ?
They look very similar.
I guess SA stands for Schaltaktor, but AT ?

Thanks

afaik the SA family is able to measure the current of each channel, and it can be used as heating actuator;

the AT family is a simple switching actuator.

ok ... I do not have any ABB acutators ... look at the link below

It ist the trailing "S" which defines if an actuator is able to measure current or not:

SA/S 8.16.5 => not able to measure current
SA/S 8.16.5 S => able to measure current

Hello Warichet,

AT -> old models
SA/S -> actual models

Indeed, the AT are mostly found on eBay.
