Power connector (X1)
The EDS500 devices are equipped with a wide range
power supply for voltages between 24 and 60 Volts DC
(power consumption see device label). The connector
is a 4-pin Phoenix plug with screw terminals.

Due to the internal overvoltage protection,
interrupt any connection to ground of the device
for the time of the measurement before you carry
out isolation measurement. This includes the
earthing of the hat rail as well as all shields of all
transmission lines and supply feedings. RJ-12 plugs
or RJ-45 plugs can establish earthing via the shield.
Extension interface (EXT)
The plug of the proprietary expansion bus is designed
RS-232 PC SUB-D9
as USB type B but uses a manufacturer specific
Signal D irection
protocol.
1 DCD Input
The configuration parameters are stored directly

on the device. In addition, a configuration stick can

Alarm-Relay (X2)
The devices are equiped with a potential free alarm
bi-directional
output (relay with isolated switchover contact). This
-
output corresponds to a device alarm and is activated
when the device looses the power supply or the alarm
LED is constantly on. The reason for the signalling of
bi-directional
an alarm can be referenced in the system alarm table.
