Semi-conductor switch elements with a residual voltage of -0.7 V (e.g.
transistors in open-collector circuits) or contacts (relays) can be used as
input switch elements.
Pin
Pin 1 = Pause input (activating func‐
tion)
Voltage with open contacts: approx. 5 V

Control:
n Potential-free contact (approx. 0.5
mA)
n Semiconductor switch (residual
voltage < 0.7 V)
2 = contact input Voltage with open contacts: approx. 5 V
Input resistance: 10 kΩ
Control:
n Potential-free contact (approx. 0.5
mA)
