Its 14-blade arrangement supports four-pole relay configurations, while open-style screw terminals provide direct field wiring access.\u003c\/p\u003e\n\u003cp\u003eThe socket supports 35 mm DIN rail mounting and panel screw mounting. DIN-rail installation should maintain full mechanical engagement across the mounting profile and avoid lateral loading on the socket body.\u003c\/p\u003e\n\u003cp\u003eThe supplied data specifies a 10 A rating per pole and a 300 VAC socket voltage rating. Actual circuit loading must remain within the ratings of both the socket and installed relay.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the 700-HN128 an active relay or a relay socket?\u003c\/p\u003e\n\u003cp\u003eA: The 700-HN128 is a passive relay socket and does not contain the relay switching element.\u003c\/p\u003e\n\u003cp\u003eQ: What relay configuration does the 700-HN128 support?\u003c\/p\u003e\n\u003cp\u003eA: The socket uses 14 blades and is specified for 4-pole \/ 4PDT plug-in relay configurations.\u003c\/p\u003e\n\u003cp\u003eQ: Can the socket be installed on a DIN rail?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The supplied specifications identify 35 mm DIN rail mounting and panel screw mounting.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eVerify the relay model and blade arrangement before inserting the relay into the socket. Confirm that all terminals are correctly identified before field wiring.\u003c\/p\u003e\n\u003cp\u003eUse conductors and protective devices appropriate for the connected circuit voltage and current. Do not exceed the specified 10 A per-pole socket rating or the installed relay rating.\u003c\/p\u003e\n\u003cp\u003eTighten screw terminals according to the applicable terminal and conductor requirements. Avoid excessive conductor stripping, exposed copper, or mechanical stress on terminal connections.\u003c\/p\u003e\n\u003cp\u003eFor DIN-rail installation, seat the socket fully against the rail and verify mechanical retention before wiring. For panel mounting, use suitable mounting hardware and maintain alignment between the socket and relay.\u003c\/p\u003e\n\u003cp\u003eRoute relay power wiring separately from low-level analog, communication, and sensitive instrumentation wiring where practical. Maintain adequate separation from high-noise switching conductors.\u003c\/p\u003e\n\u003cp\u003eWhere shielded signal wiring is present nearby, terminate shields according to the system grounding design rather than using the relay socket as a grounding point.\u003c\/p\u003e\n\u003cp\u003eInspect the socket, terminals, and relay blades for contamination, deformation, or loose connections before commissioning. Confirm electrical continuity and correct relay operation after installation.\u003c\/p\u003e","brand":"AMPHENOL","offers":[{"title":"Default Title","offer_id":43895803347034,"sku":"700-HN128","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/700-HN128.jpg?v=1787556921","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-700-hn128-relay-socket","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
