Railway Control System

Erstwhile Integra Hindustan Control Limited, INTEGRA is supplying a number of products related to Railway Control Systems for more than two decades now

Metal to Metal carbon relays, Railway signalling, have been INTEGRA’s major supply to Indian Railways and its contractors.

Being RDSO approved supplier, the reliability and quality standards of INTEGRA’s products are unquestionable.

Metal to Metal Signalling Relay (TM Type)

IEIL introduced Metal-to-Metal TM type signaling Relays in 1987 for the Indian Railways. With the technical collaboration with Integra Holding AG, Switzerland, IEIL ensured fail safe solutions for the passage of trains through interlocking functions thereby replacing the old technology of mechanical lever frames.

IEIL is an ISO 9001:20 Certified company and is an approved vendor for metal-to-metal TM type relays, as per IRS specifications, at Research Design and Standards Organization (RDSO) Lucknow.

IEIL has executed important Panel Interlocking and Route Relay interlocking Audio Frequency Track Circuit (AFTC) projects in the Indian Railways and supplies various solutions like domino panels, AFTCs, and individual and group relays directly to the controller of stores, Indian Railways, and Konkan Railways. We are also executing export orders for our relays as well.

The TM type INTEGRA Relays has been designed to meet the basic conditions of Railway Signalling Safety Requirements as mentioned below :

Any one front contact closed proves all back contacts open
Any one back contact closed proves all front contacts open
TM Type safety relays have been designed to fulfill the recommended requirements of IRS S-46, IRS : S-34 and IRS: S-23 as applicable
All front and back contacts of the relay are Metal to Metal
All the fixed contacts of our relays are twin contacts which enhance further safety level thus reduce the probability of contact failure to one thousandth of a comparable single contact.
Plug-in type Relays
Various contact configuration of Relays (i.e. 5F/3B, 6F/2B, 4F/4B etc.)

Q Series Signalling Relay (Metal to Carbon)

We are RDSO Approved vendor for this relays and it confirms specification British Railways Specification (BRS), British Standard (BS), Indian Standard (IS), Indian Railway Standard (IRS) , of modular plug-in design, the relays are secured in their mating plug boards by a retaining clip.
The relays covered in this specification is for use of railway signaling purpose. This is a DC Neutral line relays designed for typical functions like repeater, control and indication.
Interlocking of the relay and plugboard is achieved by a pin code registration system which ensures that only those relays having the same pin code as the plugboard can be interchanged.
The contact arrangement for each relay is as specified in the relevant BR standard and up to 16 pairs of contacts can be accommodated in the same housing, with front contacts being normally open and back contacts normally closed.
Contact pairs typically consist of a domed silver tip, mating with a flat, silver/ carbon tip and all contacts are rated in accordance with the appropriate BR specification.

Fuse Auto Changeover System

Fuse Auto Changeover Systems continuously monitor various fuses provided in Railway Signaling Installations. The System not only monitors the fuses, but also changeover to a Spare Fuse (provided within the system) automatically on failure of the Main Fuse. The system simultaneously monitors the status of both the Main and the Spare fuse and provides audio / visual alarm on failure of any fuse.

Types of FACS Module

Type I - Module Consist of 32 fuses of 0.6 Amp, 1.6 Amp, 4 Amp (G Type Fuse)
Type II - Module Consist of 24 fuses of 4 Amp to 10 Amp (G Type Fuse)

Features

The module has arrangement for fuses of 4U spaces vertically in a standard 19 inch rack
System operates with N+2 wires
Continuously monitoring the status of both Main and Spare fuse
Automatically changeover to a Spare Fuse on failure of the Main Fuse in less than 20 msec
Current drain from the main system is very low
Provides audio/visual alarm on failure of any fuse
Push button to test whether all indications are working
The audio alarm is resettable by push button
Operating Voltage: 24VDC or 60VDC or 110V AC
Fuses confirming IEC-127
Each PCB coated with Acrylic coating which prevents components from moisture
