Railway products ComatReleco products are designed and tested to comply with relevant railway and rolling stock equipment standards such as: EN 50155 Railway applications – Rolling stock – Electronic equipment EN 61373 Railway applications – Rolling stock equipment - Shock and vibration tests EN 45545-2 Railway applications – Fire protection on railway vehicles – Part 2: Requirements for fire behaviour of materials and components We also understand that at times we may have to also comply with local standards which can be required. ComatReleco differences to most standard industrial products...

Relays Our range includes 1 to 4 poles mechanical relays, 1 poles interface relays (mechanical or solid state). Additional monitoring or time modules are available to increase the functionality of the relay. If there is a need for another coil voltage as the ones listed on the data sheets, please contact us. Contactors - High power switching at reduced space Our standard contactors are capable of switching 4 A at 110 V DC (DC-5). This is achieved with a built-in blow magnet into a 2-poles contactor with a compact width of only 17.5 mm. ComatReleco also can build custom coil voltages away from...

Monitoring device MRx The MRx line includes monitoring devices for single and threephase loads. MRx can supervise current, voltage, apparent power, active power, frequency and cosPhi as well as ∆Phi (phase sequence) in the three-phase version. All units are designed for universal voltage. Thus, there is no need to differ between AC and DC power, neither in power supply nor in the measured values. Retrofit and replacement solutions We are continually looking for opportunities to enlarge our product portfolio in the railway market. Our engineering team can design and deliver prototypes for replacement...

Coil accessories General Information Relays C2-C9, R4, R7, R9 Protection against transients When the coil is disconnected from an electromagnet, peaks of inverse voltage appear at the terminals which can reach very high values. These pulses can be transmitted down the line associated with the coil and could possibly affect other components. In the case of a realy being operated by such devices as transistors, Triacs, etc; it may be necessary to protect against transients. Transients carried in the line High voltage surges can be carried in the supply line to the relay coil. These may appear in...

Relays General Information Contacts There are different contact types. The main distinction is between single contacts and twin contacts. While single contacts are more suitable for higher loads, twin contacts are significantly more reliable at small loads, i.e. < 24 V, < 100 mA. Contact Material There is no all-purpose contact! AgNi is used as standard material for a wide range of applications. AgNi contacts with hard gold plating (up to 5µm) are offered for applications in aggressive atmosphere. Relays with gold contacts are approved for relatively high currents (e.g. 6 A, 250 V), but in practice...

Relays General Information Standards, conformities All ComatReleco relays feature the CE mark to indicate that CE standards apply e.g. 2kV surge resistance according to EN 61000-4-5. A significant and not generally available characteristic is that the coils and in particular the connections are able to withstand the voltage spikes that may occur in practice. In addition, the relays feature various technical approvals depending on the respective relay code, and they comply with further standards and guidelines. The main technical approvals include CCC, CE, CSA, EAC, FCC, cURus, cULus, RCM, UKCA,...
