  • DGG-U200N Plug-in railway relay with 2 C/O contacts

     The DGG-U200N is the improved version of the DGG-U200 2-pole instantaneous relay.  The dimensions, pinning and specifications are identical but it is much more reliable switching very low currents (1 mA @ 5 VDC). It is therefore the perfect relay to switch mixed loads.  It has a very large voltage range: 40% - 125% of the nominal voltage. The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in…

  • DI-U900 relay – Current monitoring

Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions. The construction of the relay and choice of…

  • DI-U900N Plug-in railway relay with 2 contacts

     The DI-U900N is the improved version of the DI-U900 2-pole current monitoring relay. The dimensions, pinning and specifications are identical but it is much more reliable switching very low currents (1 mA @ 5 VDC). It is therefore the perfect relay to switch mixed loads. The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in long contact life and the now integrated contact separation prevents cross pollution of…
