takes place.
Voltage pulses and transmitters according to Class IB and IC
(low switching thresholds, small currents)
≤ 1 V corresponds to Low level
≥ 2 V corresponds to High level
U max 30 V, U no-load: 3 to 6 V
Floating contacts,
reed transmitters
Transmitters to Class ID and IE for higher currents and
power supplies
≤ 1.2 mA corresponds to Low level
≥ 2.1 mA corresponds to High level
U no-load: 7 to 9 V
