SEL-700G Relay
Installation
Rear-Panel Connections
For connecting devices at distances over 100 feet, where metallic cable is not
appropriate, SEL offers fiber-optic transceivers or the fiber-optic port. The
SEL-2800 family of transceivers provides fiber-optic links between devices
for electrical isolation and long-distance signal transmission. Contact SEL for
further information on these products.
IRIG-B Time-Code Input
The SEL-700G accepts a demodulated IRIG-B time signal to synchronize the
internal clock with an external source. Three options for IRIG-B signal input
are given, but only one should be used at a time. You can use IRIG-B (
B01
and
B02
) inputs or an SEL communications processor via EIA-232 serial
Port 3
.
The available communications processors are the SEL-2032, SEL-2030,
SEL-2020, and the SEL-2100 Logic Processor.
The models with fiber-optic Ethernet and dual copper Ethernet do not have the
terminals
B01
and
B02
for IRIG-B but have IRIG-B input via EIA-232
Port 3
.
The third option for IRIG-B is via fiber-optic serial
Port 2
. Use an
SEL-2812MT Transceiver to connect to the SEL-2030 or SEL-2032 and bring
the IRIG-B signal with the EIA-232 input. Use a fiber-optic cable pair with ST
connectors (C805 or C807) to connect to
Port 2
on the SEL-700G. Refer to
Section 7: Communications for IRIG-B connection examples and for details
about using an SEL-2401/2407/2404 as a time source.
Ethernet Port
The SEL-700G can be ordered with an optional single/dual 10/100BASE-T or
100BASE-FX Ethernet port. Connect to Port 1 of the device by using a
standard RJ45 connector for the copper port and an LC connector for the fiber-
optic port.
Fiber-Optic Serial Port
The optional fiber-optic serial port is compatible with the SEL-2812 (with
IRIG-B) or the SEL-2814 Fiber-Optic Transceivers, SEL-2664 Field Ground
Module, and the SEL-2600 RTD Module.
I/O Diagram
A more functional representation of two of the control (I/O) connections is
shown in Figure 2.11 and Figure 2.12.
