Remote Data Acquisition
-
Sometimes your sensors or the piece of equipment you are trying to control is not in a convenient place to have a PC close by. The sensors may be widely distributed through out your plant and it just wouldn’t be cost effective to run all your wiring to where the PC is. In addition, low level signals are more accurately acquired when digitized close to the signal source. In all these cases our REMOTE ACCES line of products will help. The REMOTE ACCES pods are intelligent, sensor to computer interfaces. Each pod can be used as an autonomous data logger to acquire data for later download. Or as many as 31 pods may be connected on a single two wire multidrop RS-485 network allowing a cable distance of up to 4000 ft. You can also go wireless and extend your range by adding RS-485 wireless transceivers to your serial port. Each unit comes in a rugged NEMA 4 enclosure and can withstand harsh industrial and marine environments.

IRIG-B TTL TO RS485 Converter
SPC - INS - 1010
-
Signals & Systems India Private Limited
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.
