Railway Signalling Equipments

We are engaged in manufacturing and exporting of Railway Signalling equipments.

As Per RDSO SPN-256/Rev 2002

We offer Earth Leakage Detector which is commonly known as ELD, this equipment continuously monitors the insulation of a cable with respect to the Earth. It is widely used in railways to monitor signaling cables on AC and DC circuits. The leakage value can be pre-set by the user in the range of 2K Ohm to 1 Meg ohm. Available in multiple of 4 Channels i.e. 4/8/12 Channels. The single/ multi channel equipment has twin indicating arrangements of an audio alarm plus a panel meter. It also includes a built-in Cable Insulation Tester.

as per IRS-61/2000

We manufacture safe electronic timer which replaces the thermal element relay used in signaling circuits. This fully solid state device is relay less and the time base is generated through a quartz crystal to give a high repeat accuracy. It is meant to control railway signaling circuits where a fixed time delay of 60 or 120 seconds is required. It works on 24V DC power supply.

TYPE 1010-A/B

Our delay timer is available from 1 sec to 60 minutes timings in 10 steps with a choice of ON/OFF delay. The timer is suitable for continuous working in railway signaling and indoor use. Two change-over un-energized contacts with 5 Amps rating are provided on DIN rail 35mm enclosure.

TYPE 906  Cable Insulation Tester  is similar to ELD with the most important difference that this monitors the signaling cables  in un-energized mode.  Insulation Resistance value ranging from 500 KΩ to 100 MΩ. It has a special feature, in case a pair is energized the instrument automatically stops functioning.

TYPE FR 101-A

Flasher Relay is used in railway signaling installations to give flashes at the rate of 40 to 60 per minute. Potential free contacts are given to bear a load from 3 t01 0 Amps in different models. It is so designed that the failure of any component results in no indication. Encased in a sheet metal box has also an over voltage protection. It is available in different models to work at 12 or24 or60V DC or 110V AC.
