Digital inputs
*
Nominal cur-
rent: 2.3 mA (230 VAC), impedance 100 k Ω
2.1 mA (120 VAC), impedance 75 k Ω
2.1 mA (24 VDC), impedance 11 k Ω
Due to low currents on the contacts, use gold-plated silver con-
tacts.

Signal OFF: 0.35 mA (230 VAC) 36 VAC
0.35 mA (120 VAC) 21 VAC
0.27 mA (24 VDC) 4 VDC
Electrically safe separation between the input and electronics,
floating
* Do not use for safety-relevant signals
