The 3-pole relay incorporates a 120 VAC (50\/60 Hz) operating coil driving a 3PDT contact configuration rated for up to 15 A continuous switching current. Integrated square-base blade-style terminals provide low-resistance mechanical engagement into mating sockets, while an onboard visual LED indicator displays active coil energization status.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e700-HB33A1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.09 kg (0.20 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard 700-HB series square base relay housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-25 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e120 VAC (50\/60 Hz) coil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact Configuration\u003c\/td\u003e\n\u003ctd\u003e3PDT (3 Pole Double Throw)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Rating\u003c\/td\u003e\n\u003ctd\u003e15 A maximum per pole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase \/ Terminal Type\u003c\/td\u003e\n\u003ctd\u003eSquare base; Blade-style plug-in terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVisual Status\u003c\/td\u003e\n\u003ctd\u003eOnboard LED coil status indication\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication \u0026amp; Deterministic Networking\u003c\/h3\u003e\n\u003cp\u003eThe 700-HB33A1 provides robust galvanic and physical isolation between low-voltage digital output cards and high-power AC field loads. High-capacity silver-alloy contacts resist arc erosion and contact welding caused by inductive switching transients on solenoid coils and motor contactor circuits. Rapid contact response times ensure deterministic signal execution across PLC digital output loops, while onboard visual LED illumination gives panel operators immediate diagnostic feedback on output relay coil actuation states without interrupting control voltage circuits.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What coil operating voltage and frequency are required for the 700-HB33A1 relay?\u003c\/p\u003e\n\u003cp\u003eA: The relay coil operates on 120 VAC nominal control power at 50\/60 Hz.\u003c\/p\u003e\n\u003cp\u003eQ: What contact configuration and maximum current capacity are provided by this model?\u003c\/p\u003e\n\u003cp\u003eA: The relay features 3PDT (3 Form C) contacts rated for a maximum continuous load current of 15 A per pole.\u003c\/p\u003e\n\u003cp\u003eQ: How is visual diagnostic status indicated on the 700-HB33A1 relay housing?\u003c\/p\u003e\n\u003cp\u003eA: An integrated LED status indicator illuminates when 120 VAC control voltage is applied across the relay coil terminals.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure all panel control circuit voltages are de-energized before inserting or removing the relay from its socket.\u003c\/li\u003e\n\u003cli\u003eAlign the blade-style pins of the 700-HB33A1 with the corresponding slot configuration of the matching square-base relay socket.\u003c\/li\u003e\n\u003cli\u003ePush the relay firmly into the socket until the blade terminals seat fully and the mechanical retaining clip locks over the relay body.\u003c\/li\u003e\n\u003cli\u003eWire field output loads to the socket screw terminals, verifying that continuous circuit current does not exceed the 15 A contact rating.\u003c\/li\u003e\n\u003cli\u003eApply 120 VAC coil control power and confirm LED illumination and mechanical contact switching states using a circuit tester.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52739562242328,"sku":"700-HB33A1","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/700-HB33A1_Cocoai.jpg?v=1789975195","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-700-hb33a1-industrial-relays","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
