× GPS SYNCHRONIZED CLOCK SYSTEMS

IRIG-B TTL to RS485 Converter converter is used to convert the IRIG-B TTL to IRIG-B RS485 signal. The IRIG-B TTL signal is a time synchronization protocol that can be transmitted 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 time synchronization.

IRIG-B TTL to IRIG-B RS485 provides easy and affordable connectivity to substation equipment and power generation and distribution 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 these Plug-N-Play units, 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 additional brackets. It has an inbuilt power supply module, therefore, doing away with the need for an external power adapter. It consists of a BNC connector for IRIG-B TTL input and a terminal block for IRIG-B RS485 outputs. There is a LED indication for Power & signal outputs. The power supply can be customized when ordering
