CROMPTON GREAVES has developed Data Logger which is failsafe electronic system which serves the purpose of reliable monitoring of signaling data and input.

Data Logger system consist of Data Logger equipment and Central Processing Unit and is designed to fit in DIN Standard enclosures. It accommodates 512 Nos. Digital inputs, 32 Nos. Analog inputs and 16 Nos. Digital outputs. The equipment can be operated in local mode with the help of keyboard and 80 character LCD display.

The System chronologically monitors and record the status of various field inputs like Track Circuits, Point Machines, Axle Counters, Push Button and Voltages of Power supply etc. It can generate audio visual alarm under error condition. The system can also display and print status and failure report of logged events.

ELECTRIC POINT MACHINES

CROMPTON GREAVES offers Power operated Electric Point machines to fulfill the strict requirement of safety and reliability for operation of points. The Point machines are self contained, easy to install and require minimum maintenance under operating conditions.

The range includes :

• 110 V DC, Non trailable, low thrust (450 kg), 143 mm stroke Point machine.
• 110 V DC, Non trailable, high thrust (700 kg), 143 mm stroke Point machine.
• 110 V DC, Non trailable, 220 mm stroke Point Machine to operate high speed turnouts TWS 60 kg & TWS 52 kgs with external clamp point locks.

All Point machines manufactured by Crompton Greaves use high grade material, well proven components with superior finish techniques. This ensures reliable operation and long service in the hostile track side environment.

Crompton Greaves can also develop and supply Point machine to suit any specific requirement / specification.
