ABB ETL500 P7LC 1KHL015000R0001 High capacity operation PLC group

Description

Investment protection
■ Any PLC equipment can be retrofitted with
the AMX500 to increase capacity. This enables
existing communication infrastructure to be used
more efficiently without the need for high reinvestment. For example, one AMX500 is often
sufficient for the additional transfer of a few
speech and data services; the requirement for
costly wideband equipment is dispensed with.
■ The concept allows for a seamless transition from
an ETL500 equipment working in standard
mode to a PLC set operated in high-capacity
mode by adding the AMX500 unit housed in its
own subrack.
■ Retrofitting and upgrading an ETL500 equipment
into one working in high-capacity mode is possible any time on site.
■ Frequency allocation in an existing network will
remain unaffected, i.e. there is no need to change
line traps and coupling filters.
Operational flexibility, modes of operation
Unique features, such as single-step digital frequency
conversion, automatic channel equalization, configurable AF options, event recorder, built-in test
facilities, to name just a few, add to the operational
flexibility.

The Direct Digital Synthesis method, which is used
to generate the RF signal, results in excellent quality
and stability of the AF to RF and RF to AF conversions. The carrier frequency parameters detailed
below are easily configured by means of the userfriendly MMI500.
■ Carrier frequency: Can be set in steps of 500 Hz
in the frequency range from 24 to 500 kHz
■ Number of channels: 1 or 2
■ Channel-bandwidth: 4 or 8 kHz
■ Position of the individual sidebands: Can be
configured individually to be in the upright or
inverted position
The ETL500 design is unique as it combines
robustness and transparency of analogue equipment
with the advantage of increased transmission capacity provided by digital transmission equipment.
This feature makes the equipment compatible with
existing analogue PLC systems and results in outstanding flexibility with regard to the applications.
The system may be used in various modes of operation depending on the requirements, type of services, line conditions, etc. Three examples illustrate
possible ways of using a given frequency band and
demonstrate the versatility of the ETL500 system.
Example 1:
When using ETL500 single channel equipment the
capacity can considerably be enhanced by adding
the AMX500 unit. A possible configuration is
illustrated below. This arrangement permits a data
channel with a transmission rate of 4800 bps to
be superimposed above the speech channel, within
which the tones for protection signalling are allocated.
