Featuring a single-channel relay output (make contact), it provides seamless integration for controlling ohmic and inductive loads up to 230 V AC\/DC. Its flexible connection technology supports 2-, 3-, and 4-wire configurations, making it a versatile choice for a wide range of automation tasks. By offering 2500 V AC electrical isolation between the field side and the internal K-bus, the \u003cstrong\u003eKS2701\u003c\/strong\u003e ensures robust protection of your PLC and communication infrastructure against voltage transients.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eDesigned for the modular Beckhoff Bus Terminal system, the KS2701 is housed in a compact, pluggable polycarbonate enclosure. It is engineered to handle substantial switching demands, featuring a steady-state current rating of 3 A and the capacity to handle peak currents of up to 50 A for short durations (100 ms). The terminal requires no manual address or configuration settings, allowing for \"plug-and-play\" deployment. With its integrated surge voltage protection (starting at 400 V AC), this terminal is exceptionally well-suited for switching inductive loads, such as contactor coils or small solenoid valves, while maintaining precise 2–4 ms switch-off times.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eFeature\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\u003eKS2701\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003e1 x Relay (Make contact)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e0 to 230 V AC\/DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Steady Current\u003c\/td\u003e\n\u003ctd\u003e3 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePeak Current\u003c\/td\u003e\n\u003ctd\u003e50 A (100 ms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitch-off Time\u003c\/td\u003e\n\u003ctd\u003e2 to 4 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrical Isolation\u003c\/td\u003e\n\u003ctd\u003e2500 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBit Width\u003c\/td\u003e\n\u003ctd\u003e2 outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP 20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.055 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is surge voltage protection important for this terminal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen switching inductive loads (like solenoids or large contactors), the collapsing magnetic field generates a high-voltage transient (back EMF) that can damage electronic components. The integrated surge protection (starting at 400 V) suppresses these spikes, significantly extending the relay's service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this terminal for low-voltage signal switching?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile the KS2701 is robust enough for 3 A loads, the gold-free contacts are optimized for general-purpose switching. For extremely low-current, low-voltage signal applications (e.g., \u0026lt; 10 mA, \u0026lt; 5 V), consider using a terminal with gold-plated contacts to ensure reliable signal continuity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this terminal require configuration in TwinCAT?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo, the KS2701 is a self-configuring device. Once connected to the K-bus, the system detects it automatically, occupying 2 bits in the process image. No manual addressing is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the recommended fuse for this terminal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTo protect the relay contacts from welding during a short circuit, you should install a fast-acting fuse rated at ≤ 10 A in series with the load.\u003c\/p\u003e\n\u003ch3\u003eInstallation Guidelines and Best Practices\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e The KS2701 uses spring-actuated terminals. Use a screwdriver to actuate the spring, insert the wire (0.08–1.5 mm²), and ensure a stripping length of 9–10 mm. This connection method is highly vibration-resistant and requires no re-tightening over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Management:\u003c\/strong\u003e With a steady load of 3 A, the terminal remains efficient; however, when mounting several relay terminals side-by-side, be mindful of cumulative heating. Ensure the control cabinet is ventilated to keep the ambient temperature within the 0–55 °C range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding \u0026amp; Isolation:\u003c\/strong\u003e The 2500 V AC isolation is critical for safety. Ensure your field wiring for the 230 V circuit is kept physically separate from low-voltage (24 V DC) sensor and communication wiring to prevent capacitive coupling and potential safety hazards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e The terminal snaps directly onto 35 mm DIN rails (EN 60715). Use the integrated lock mechanism to secure the terminal in place, especially in high-vibration environments like industrial presses or high-speed conveyors.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BECKHOFF","offers":[{"title":"Default Title","offer_id":53106607096171,"sku":"KS2701","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/ks2701-oe11gexbkzo.png?v=1776245274","url":"https:\/\/www.plcprotech.com\/fr\/products\/beckhoff-ks2701-bus-terminal-relay-output","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
