Device Description
The digital signal input (input ports) goes to the logic state "LOW"
when the pin "In" and the center pin "GND" are bridged, otherwise the
state is "HI". The text outputs associated with the "LOW" and "HI"
states can be defined in the Input Ports configuration
. In the de-
fault configuration, the logic states are inverted so that the state "HI"
is assumed for a bridged contact.
This means that there is only a connection between the center pin
(COM) and the NC-pin (Normally Closed) for the output ports in the
"Off" state. If the relay is in the "On" state, then there is only contact
from the center pin (COM) to the NO-pin (Normally Open).
As an alternative to the connection of "In" and "GND", voltages of up to 24 V (= VIn-
max) can be connected to the input "In". For voltages less than 4 V the state goes to
"LOW", for voltages greater than 8 V the "HI" state is assigned.
1.5 Redundant Voltage Supply
If the device and the connected switch support Power-over-Ethernet, the power supply
via PoE has priority and the device is powered only via PoE. Alternatively, the device can
be supplied via up to two power supply units. If both power supplies (only ESB 7214) are
connected at the same time, the current is split up. The current distribution depends on
the difference between the output voltages of the two power supplies.
