Why IRIG-B TTL to IRIG-B RS485 required?
The IRIG-B TTL signal is a me synchronizaon protocol that can be
transmied up to 50m maximum using coaxial cable. So the relay
which is to be received the IRIG-B TTL signal may be far away from the
IRIG-B source. The relay may be not able to synchronize with the GPS.
To avoid such an incident in the field, some of the relays have provision
to receive IRIG-B RS485 signal. The IRIG-B RS485 signal can able
travel up to 1200m without any booster. All Time source equipment
may not be supplied with IRIG-B RS485 signal output. The converter
will act as a bridge between GPS Time source and Relays for me
synchronizaon.

Installaon of the Enclosure
The System is assembled in a Wall Mountable Enclosure
The following steps are to be carried out:
Place the unit in the control panel and fix the mounng
brackets on the front side of the rack using Screws.
Ensure that there is sufficient space between the connecon
side of the rack and the control panel to allow for the
connecon of cables to the System.
Note: At higher temperatures, acve cooling/venlaon is
recommended.
Overview
SLC-1010 series converter is used to convert the IRIG-B TTL to IRIG-B
RS485 signal. It provides easy and affordable connecvity to
substaon equipment and power generaon and distribuon
equipment. It converts the IRIG-B TTL input format like 002, 004, 006
& IEEE1344 and IEEE C37.118 to RS485 output with the same format.
With this Plug-N-Play unit, you can expand your IRIG-B TTL signal to a
long distance. The converter supports 2-wire RS-485. It can able to
support a minimum of 32 nodes or 128 nodes (1/4 UL) based on unit
load. It is rugged and surge-protected equipment. Its cabinet can be
mounted directly on a wall without the need for addional brackets. It
has an inbuilt power supply module, therefore, doing away with the
need for an external power adapter. It consists of BNC connector for
IRIG-B TTL input and a terminal block for IRIG-B RS485 outputs. There
is a LED indicaon for Power & signal outputs. The power supply can
be customized when ordering.

Connecon Details
Operaon
IRIG-B TTL input is the source for this system. IRIG-B RS85 is the
output from this converter. The system has a BNC connector for
IRIG-B TTL input and a terminal for IRIG-B RS485 output. Terminal
block indicated with IRIG-B+ (Posive Signal) and IRIG-B-(Negave
Signal) of RS485 output. SIG LED indicaon is provided to know
the input signal from the IRIG-B source. Verify the Status LED aer
connecng the Power Supply and IRIG-B input.
The System is an installaon device. Installaon and commissioning
may only be carried out by suitably qualified specialist personnel. In
doing so the respecve country-specific specificaons must be
observed
Before commissioning ensure that:
The power supply has been connected correctly and electrical
shock protecon is in place
The earth wire is connected
All output cables are suitably sized
Sufficient convecon is guaranteed
Note: The equipment may contain life-threatening components
and a high level of stored energy.
It will glow Red when the converter is powered ON.
It will go OFF when no power supply.
IIt will blink Green when IRIG-B input available.
It will go OFF when IRIG-B input not available.

AC Power Supply
Aenon should be paid to the following when connecng the
power supply
Correct voltage type AC
Voltage level
The power feed is via a 3 pin phoenix combicon connector. The
phase should be connected to ‘L(+)’. Neutral should be Connected
to ‘N (-)’. Connect the input connector to the mains power supply
and switch the line circuit breaker ON.
Note: The System can be damaged if incorrect voltage is connected
DC Power Supply
Ensure that the external power supply is switched off. When
connecng the supply cable make sure that the polarity is correct
and the equipment is earthed. The power feed is via a 3pin phoenix
combicon connector. The posive pole should connect to ‘L (+)’. The
negave pole should be connected to ‘N (-)’. Connect the input
connector to the mains power supply and switch the line circuit
breaker ON.
Note: The System can be damaged if incorrect voltage is connected.
Safety and Warning Instrucon
Please read these instrucons fully in order to guarantee safe
operaon of the equipment and to be able to use all the funcons.
Cauon: Never work on an open unit when voltage is applied!
Danger to life!
