CHAPTER 1: GETTING STARTED ABOUT YOUR NEW DDFR UNIT
DISTRIBUTED DIGITAL FAULT RECORDER – INSTRUCTION MANUAL 5
1.2.5 The Physical DDFR Unit
Power Supply
Each DDFR is supplied in one of two power supply types:
• Low Voltage DC: 24 to 48 VDC
• High Voltage
• AC: 120 V to 230 V
• DC: 110 V to 250 V
FIGURE 1–1: DDFR Terminal Block
Please ensure, before connecting a DDFR to the power supply, that the unit you have in
front of you is compatible with the power supply in your facility.
LED Indicator Light
A single green LED is located on the front of the DDFR. This LED indicates only that power
is being supplied to the DDFR unit.
Ethernet Communications Port
A single Ethernet communications port is provided at the rear of the DDFR. This port can
be used for "fresh" setup and/or configuration of a new DDFR (see chapter 3), but its main
function is to act as the sole communication port for data from all the relays in your facility
to the DDFR unit and from this unit to your computer. For examples of typical connections
from your relays to the DDFR unit (and your computer), see chapter 4.
In addition, you can communicate with any of your installed DDFR units via this Ethernet
port in order to configure or reconfigure any of them. This single port is able to process
these multiple inputs and outputs by connecting it to a port on an Ethernet switch such as
the GE MultiLink switch.
In short, the DDFR unit you have purchased, offers you the ability to configure your entire
range of (DDFR-supported) relays and conveniently view and archive the fault information
accumulated within these relays from the computer keyboard on your desk.
