Mors Smitt Railway Technology Signalling & rail infrastructure Jfc u I SERVING SAFETY

New solutions are co-designed with railway operators and contractors, creating ever safer railway networks

introduction Mors Smitt is a leading designer and manufacturer electro-mechanical components (e.g. relays, circuit breakers and transducers) and form, fit & function electrical control panels designed according to international railway standards. Signalling & rail infrastructure market The extensive knowledge build up in the rolling stock market is nowadays used in the signalling & rail infrastructure market by supplying relays and customer specific test and measuring equipment. Due to increasing performance requirements of railway lines and the need for modernisation and replacement of...

Signalling relays Mors Smitt is an authority when it comes to signalling relays. We have inhouse expertise and manufacturing of various standards used in several networks: • B-style relays (Netherlands, US) • N.S1 relays (French standard SNCF) • Q-style relay (British Rail Standard BR930) Currently hunderds of relay designs are being manufactured meeting the strict requirements of railway operators. Mors Smitt can either manufacture new relays or provide a comprehensive refurbishment & repair service for existing units with re-certification. Repair, retrofitting, maintaining, testing...

Our production capacity of signalling relays is flexible and responsive. Supply against low or high volumes orders is equal. Product quality is guaranteed by using the latest technology production equipment, well trained, dedicated and experienced staff, end-of-line testcomputers assuring compliancy to specific railway standards. ‘Quality and safety are the drivers of our thinking and doing’

N.S1 relays N.S1 signalling and vital relays are a consistent, adaptable range of relays with plug-in connection, small size, modular construction, low power consumption, compliance to French and SNCF standards, conformity to UIC recommendation, Ag / Ag CdO contacts and 24 V standard voltage. Line relay Point operating relay Post relay See our brochure ‘Signalling and vital relays N.S1’ for more detailed information on www.morssmitt.com. BR930 relays BR930 relays are of modular plug-in design. Interlocking of the relay and plugboard is achieved by a pin code registration system which...

GRS type B1 & B2 relay inhouse verification Contact operation, detection and adjustment Special calibration tools have been developed to check the operation of the N/O and N/C contacts. The contact operation are visualised by LED’s to be able to calibrate the contacts and guarantee proper operation of each contact. Calibration of slow pick-up and slow release B1 relay Calibration of B2 code transmitter Calibration of B2 vane relay Contact pressure measurement The contact pressure is measured mechanically, evaluated and adjusted to guarantee the quality of the electrical connection. Contact...

GRS type B1 & B2 relay inhouse testingTestingDutch Railways has certified Mors Smitt as Red Label Expert on B1/B2 type relays. High voltage insulation test Each relay is submitted to a high voltage insulation test to check the insulation properties of the relay. Degraded coils, wiring and bases van be detected and replaced. Pick-up and drop-away test To inspect the calibration the pick-up (voltage and current) and drop-away values are measured. Also the resistance of the coil is determined to be within the tolerances. If not, the coil will be replaced. Operational simulation test An...

Safety-critical relays The safety-critical relay portfolio comes from safety rolling stock applications such as automatic braking units (ATB) or automatic train operating systems (ATO). There is an increasing interest to use this proven technology in trackside signalling applications because it is space saving and very economic. There are four groups: general purpose relays, semi-vital relays, safety-critical relays and vital relays. Unique relay features such as spring enchanced gravity function in combination with 'non-weldable' double make - double break contacts and weld-no-transfer...

Retrofit and replacement solutions Extending life expectancy by upgrading obsolete and outdated rail network installations is mandating the replacement and retrofit of obsolete components. Many authorities recognize Mors Smitt's expertise in this field, especially for retrofit and replacement with form, fit and function compliant systems (FFF). This is an area of increasing significance: • Inhouse design and prototyping of new solutions • Customer specific type testing and validation • On site implementation and commissioning • After sales support Mors Smitt delivers perfect and...
