Description

Plug-in electronic railway pulsing relay with two change-over contacts, suitable for AC coil voltages with a frequency of 50/60 Hz. When the relay is activated the coil starts with an interval. The pulse time and interval time are equal. The pulsing frequency is adjustable with a lockable knob. The relay can also be supplier with a fixed pulsing frequency (no knob). The relay is standard equipped with double zener diode coil protection.

The construction of the relay and choice of materials makes the FDA-U300 relay suitable to withstand low and high temperatures, shock & vibrating and dry to humid environments.

No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.

Compact design, choice of many options and a wide range of sockets makes the FDA-U300 relay an easy and flexible solution to use.

Application

These relay series are designed for demanding train borne applications. The FDA-U300 is used in applications where a pulse frequency in output is
necessary after activating the relay.
