Earth Leakage Director
RDSO/SPN/256/2002
Commonly known as ELD, this  equipment continuously monitors the insulation of a cable with respect to the Earth. 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.

Cable Insulation Tester Type906
Cable Insulation Tester is similar to ELD with the most important difference that this monitors the signaling cables but only in un-energised mode with leakage value setting from 500K to 10M ohm. It has  a special feature-in case a pair is energized the instrument automatically stops functioning.

Fail Safe Electronic Timer
as per IRS- 61/2000
Fail Safe Electronic Timer 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 sec.
