DESCRIPTION :
It is used for BLOCK WORKING in Single line sections (Both RE and NON - RE) of INDIAN RAILWAYS. The instrument is designed to work on 24V DC voltage (normal) with variation between 19.2V to 28.8V. It works on Frequency modulated ( FM ) system utilizing FM TRANSMITTER & RECEIVER to immune from the effects of extraneous interference.
The instrument is designed to work on 24V DC voltage (normal) with variation between 19.2V to 28.8V. It works on Frequency modulated ( FM ) system utilizing FM TRANSMITTER & RECEIVER to immune from the effects of extraneous interference. Maximum Current drawn by the internal circuit is not more than 700mA and by the line circuit is not more than 110 mA during normal sequential operation. The instrument is suitable to work with a temperature variation from 0 °C to 55 °C with relative humidity of 95% at 40°C. Locking and sealing facilities are also provided in the instrument to prevent un-authorised tampering.
