The D-U200N-W is the improved version of the famous D-U200-W 4-pole instantaneous safety critical 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. Weld-no-transfer contacts are standard. <\/p>\n
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 contacts better. The operating temperature range is now -50 to + 85 Celsius. The IP40 dust ingress protection offers adequate protection allowing the relay to \u201cbreath\u201d ensuring long life whilst switching higher DC and inductive loads. The back EMF coil protection diode comes standard with the D-U200N-W series. The information on the relay cover is extended with serial no. and data matrix code for ease of traceability. <\/p>\n
The mechanical design and construction of the D-U200N-W relay is so rugged that it is fit to last in salt laden atmospheres, low and high temperatures, very dry and very high humidity, shock and vibrations and high altitudes. Several operators use this relay since the 1970\u2019s and without a single incident. Indeed proven reliable and designed to survive train life! The ultra-compact design, light weight, many options and the wide choice of sockets makes this the most flexible solution and preferred choice of many customers.<\/p>","protected":false},"featured_media":1131,"template":"","meta":{"_acf_changed":false,"sku":"D-U200N-W","external_key":"D-U200N-W","parent_external_id":"P-D Instantaneous Relays","grandparent_external_id":"GP-D platform","product_type_description":"ChildProduct","product_short_description":"Instantaneous relay, weld-no-transfer","product_long_description":"The D-U200N-W is the improved version of the D-U200-W 4-pole instantaneous safety-critical relay.
