Product Code |
Series PTIO - Push-in sensor and actuator terminal block |
Nominal Cross-Section 1.5 - 1.5mm² nominal conductor cross-section |
Version S - Fixed version code in both listed PTIO models |
Potentials 3 - Three potentials, four connections and two connection levels |
PTIO terminals use push-in connections and mount on NS35/7.5 rail. The /3 model has three potentials and four conductor connections; /4 adds a fourth potential and a fifth connection. Select by the required electrical paths and the terminal outline, keeping the individual potentials distinct.
