Advanced technology for telecomms relays

The FTR-C1 and C2 relays are specifically designed for switching telecommunication networks voltage (TNV) circuits.

The FTR-C1 and C2 relays are specifically designed for switching telecommunication networks voltage (TNV) circuits.

These relays offer supplementary insulation class properties, allowing a working voltage of 250V.

Both relays have a high isolation and high breakdown-voltage properties in telecomms applications, which can be subjected to overvoltages, for example switched lines that leave the building, connecting to the outside world.

Normally these lines are a twisted pair, and in case of faults, can be linked to metallic conductors exposed to lightning and AC power lines.

The FTR-C1 and FTR-C2 relays are perfectly suitable to switch interfaces such as analogue telephone lines and modems (POTS), ISDN U interfaces, IP phones, modems, DSLAM networks and xDSL lines.

The FTR-C1 relay meets the Telcordia 2nd level lightning surge test (5kV, 2x10us, 500A surge current).

The FTR-C2 relay offers a 2mm contact gap, for applications such as switching two different circuits by the same relay, and other applications, which need additional insulation requirements between open contacts.

The FTR-C2 relay is therefore very suitable in European and US voice modem applications.

This relay also offers the possibility to eliminate the insulation transformer when used to switch the ringer circuit generator or power source (primary circuit) between the phone line and TNV circuit.
