Product Characteristics
4.4 SCALANCE X101-1LD
Warning
The SCALANCE X101-1LD device is designed for operation with safety extra-low voltage.
This means that only safety extra-low voltages (SELV) complying with IEC950/EN60950/
VDE0805 can be connected to the power supply terminals.
The power supply unit to supply SCALANCE X101-1LD must comply with NEC Class 2
(voltage range 18-32 V, current requirement 200 mA).
If the device is connected to a redundant power supply (two separate power supplies), both
must meet these requirements.
The signaling contact can be subjected to a maximum load of 100 mA (safety extra-low
voltage (SELV), DC 24 V).
Never connect SCALANCE X101-1LD to AC voltage.
Never operate SCALANCE X101-1LD with DC voltage higher than 32 V DC.
Signaling Contact
The signaling contact is connected to a 2-pin plug-in terminal block. The signaling contact
(optical relay contact) is a floating switch with which error/fault states are signaled by contact
separation.
Figure 4-17
The following errors/faults can be signaled by the signaling contact:
• The failure of a link at one of the two monitored ports.
• The failure of one of the two redundant power supply units.
Connecting or disconnecting a communication node at an unmonitored port does not cause
an error message.
The signaling contact remains activated until the error/fault is eliminated or until the current
status is applied as new desired status by the button.
When turning off the device, the signaling contact is always activated (open).
