(1) DC-12: control of resistive loads and of solid state loads isolated by opto-coupler, L/R
y
1 ms.
(2) DC-13: switching electromagnets, L/R
y
2 x (Ue x Ie) in ms, Ue: rated operational voltage,
Ie: rated operational current (with a protection diode on the load, DC-12 curves must be used
with a coefficient of 0.9 applied to the number in millions of operating cycles).
