Plug-in electronic railway flashing relay with four changeover contacts for reliable switching of very low currents (1 mA @ 5 VDC) up to currents of 10A @ 110VDC. When the relay is activated the coil starts with an interval. The pulse time and interval time are equal. The relay is supplied with a fixed pulsing frequency. The relay can also be supplied with an adjustable pulsing frequency (relay with knob).

The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the coil.

The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in long contact life. The integrated contact separation prevents cross pollution of contacts. On the relay cover the serial number and data matrix code are shown for ease of traceability.

The construction of the relay and choice of materials make the FDA4-U200N relay suitable to withstand low and high temperatures, shock & vibration and dry to humid environments.

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

Compact design, choice of many options and a wide range of sockets make the FDA4-U200N relay an easy and flexible solution to use.

New coil design in combination with other contact configuration leads to reduced energy consumption of more than 50% with same technical specifications (option G).
