The internal system logic coordinates high-velocity bus switching signals, enabling synchronous relay actuation while scaling system I\/O density within compact cabinet layouts. Internal supervisory circuits enforce firmware flash compatibility checks between master and expansion modules during boot cycles, locking safety outputs open if logic handshake cycles detect communication timing errors or voltage irregularities.\u003c\/p\u003e\n\u003ch3\u003eDeliverable Package Listing\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Omron G9SX-EX401-RC Flexible Safety Expansion Unit\u003c\/li\u003e\n\u003cli\u003e1 x Pre-fitted Removable Spring-cage Terminal Block Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Technical Instruction Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCabinet Installation \u0026amp; Wiring Rules\u003c\/h3\u003e\n\u003ch4\u003eEnclosure \u0026amp; Mounting Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSnap the housing securely onto standard 35-mm DIN rail installed inside an IP54-rated industrial panel.\u003c\/li\u003e\n\u003cli\u003eProvide at least 50 mm clearance above and below the module housing to allow adequate air circulation and conductor routing space.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWiring \u0026amp; Connection Practices\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eStrip cable ends 8 mm to 9 mm; push solid or ferruled conductors directly into spring-cage clamp openings.\u003c\/li\u003e\n\u003cli\u003eDepress the orange terminal release lever with a flat-blade screwdriver (0.6 mm x 3.5 mm) when disconnecting flexible stranded wires.\u003c\/li\u003e\n\u003cli\u003eRun output contact lines separately from variable frequency drive motor cabling and high-voltage power lines to prevent EMI coupling.\u003c\/li\u003e\n\u003cli\u003eConnect a 24 VDC PELV\/SELV power supply unit to maintain galvanic isolation and transient protection across control loops.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the maximum response delay when de-energizing safety outputs?\u003c\/p\u003e\n\u003cp\u003eThe unit opens its instantaneous safety contacts within 10 ms maximum after receiving a shut-off command from the main unit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this expansion module operate independently without a master controller?\u003c\/p\u003e\n\u003cp\u003eNo, the expansion unit requires direct side-connector attachment to a master G9SX Advanced Unit to receive logical control signals.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat load ratings are supported by the output contacts?\u003c\/p\u003e\n\u003cp\u003eThe relay contacts support a maximum resistive load of 3 A at 250 VAC or 3 A at 30 VDC, with a rated carry current of 3 A.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does the spring-cage mechanism protect against conductor detachment?\u003c\/p\u003e\n\u003cp\u003eSpring-cage terminals maintain constant spring tension on inserted wires, preventing loose connections caused by continuous vibration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the electrical lifecycle rating under full load conditions?\u003c\/p\u003e\n\u003cp\u003eThe internal relay contacts offer a minimum electrical durability of 100,000 switching operations at rated resistive load.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat function does the auxiliary output serve?\u003c\/p\u003e\n\u003cp\u003eThe auxiliary PNP transistor output provides a non-safety status signal limited to standard monitoring functions on PLCs or indicators.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat supply voltage limits must be maintained during operation?\u003c\/p\u003e\n\u003cp\u003eThe internal logic circuitry requires a 24 VDC power source operating within an allowable voltage range of 20.4 VDC to 26.4 VDC.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan this expansion module generate delayed safety outputs?\u003c\/p\u003e\n\u003cp\u003eNo, model G9SX-EX401-RC features four instantaneous relay safety outputs and does not contain OFF-delay timing hardware.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Omron","offers":[{"title":"Default Title","offer_id":47306651828397,"sku":"G9SX-EX401-RC","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/G9SX-EX401-RC.jpg?v=1789966867","url":"https:\/\/www.maxwellplc.com\/ru\/products\/g9sx-ex401-rc-omron-flexible-safety-unit-g9sx-series","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
