Plug-in industrial electronic timer relay with four change-over contacts.When the relay is activated there is a delay on pull- in. The delay time is adjustable with a lockable knob. The relay can also be supplied with a \ufb01 xed time delay (no knob). The relay is standard equipped with two LEDs which indicate the presence of power supply and the energizing of the coil. Optionally equipped with magnetic arc blow-out for high breaking capacity and long contact life. Proven reliable operation in switching high DC voltage \/ inductive loads and low currents. No external retaining clip needed as integrated \u2018snap-lock\u2019 will hold relay into socket under all circumstances and mounting directions. The construction of the relay and choice of materials makes the TDB4 relay suitable to withstand low and high tempera- tures, shock & vibrating and dry to humid environments. Compact design, choice of many options and a wide range of sockets makes the TDB4 relay an easy and \ufb02 exible solution to use.<\/p>","protected":false},"featured_media":7234,"template":"","meta":{"_acf_changed":false,"sku":"TDB4 series","external_key":"TDB4 series","parent_external_id":"P-Industrial Plug-in Power relays","grandparent_external_id":"GP-Transmission and Primary Distribution","product_type_description":"ChildProduct","product_short_description":"delay-on timer relay","product_long_description":"Plug-in industrial electronic timer relay with four change-over contacts.
