It provides automatic signal control and track isolation to deliver realistic and reliable block signalling.\u003c\/p\u003e\n\u003cp data-start=\"339\" data-end=\"760\"\u003eThe module monitors trains entering and leaving a protected section and automatically controls the associated signals. When a train enters the section, the signal at the entrance is set to danger (red) and the track section is isolated to stop following trains. The SEC1A-DC also communicates with preceding sections to correctly display yellow and double-yellow aspects when used with 3- and 4-aspect signalling systems.\u003c\/p\u003e\n\u003chr data-start=\"2193\" data-end=\"2196\"\u003e\n\u003ch3 data-end=\"989\" data-start=\"974\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-start=\"762\" data-end=\"849\"\u003eMonitors trains entering and leaving a protected section of track.\u003c\/li\u003e\n\u003cli data-start=\"851\" data-end=\"945\"\u003eAutomatically sets the entry signal to danger (red) and isolates the section to stop trains.\u003c\/li\u003e\n\u003cli data-start=\"947\" data-end=\"1072\"\u003eCommunicates with previous sections to display correct yellow and double-yellow aspects when using 3- and 4-aspect signals.\u003c\/li\u003e\n\u003cli data-start=\"1074\" data-end=\"1191\"\u003eAllows the final section to simulate a return to clear using timers for realistic 3- and 4-aspect signal operation.\u003c\/li\u003e\n\u003cli data-start=\"1193\" data-end=\"1266\"\u003eForces signals to danger when points are not set in the train’s favour.\u003c\/li\u003e\n\u003cli data-start=\"1268\" data-end=\"1357\"\u003eAllows signals to be forced to danger via an external input, ideal for starter signals.\u003c\/li\u003e\n\u003cli data-start=\"1359\" data-end=\"1455\"\u003eSupports 2-, 3-, and 4-aspect LED signals, with \u003cstrong data-start=\"1407\" data-end=\"1438\"\u003eSEC1A-DC for common-cathode\u003c\/strong\u003e signal wiring.\u003c\/li\u003e\n\u003cli data-start=\"1457\" data-end=\"1539\"\u003eSupports bidirectional running with 2-aspect signalling at each end of the line.\u003c\/li\u003e\n\u003cli data-start=\"1541\" data-end=\"1613\"\u003eIncludes additional station stop modes and an additional Dapol output.\u003c\/li\u003e\n\u003cli data-start=\"1615\" data-end=\"1727\"\u003eRemembers section occupancy when power is removed and automatically restores signal states when power returns.\u003c\/li\u003e\n\u003cli data-start=\"1729\" data-end=\"1814\"\u003eSimple to set up while remaining fully configurable for highly realistic operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"2193\" data-end=\"2196\"\u003e\n\u003ch3 data-start=\"2027\" data-end=\"2053\"\u003eElectrical Requirements\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-start=\"1816\" data-end=\"1879\"\u003eRequires a 12V DC power supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"2193\" data-end=\"2196\"\u003e\n\u003ch3 data-start=\"2198\" data-end=\"2224\"\u003eDocumentation \u0026amp; Support\u003c\/h3\u003e\n\u003cp data-start=\"1881\" data-end=\"2042\"\u003eFor detailed information on installation, wiring connections, and troubleshooting, please download the latest instruction manual:\u003c\/p\u003e\n\u003cp data-end=\"2221\" data-start=\"2076\"\u003e\u003ca rel=\"noopener\" title=\"SEC1BDC\" href=\"https:\/\/drive.google.com\/file\/d\/1xrprSyIYXQUJ1NL_IjYh-SE36DREvtOk\/view?usp=sharing\" target=\"_blank\"\u003eProduct Instruction Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"BLOCKsignalling","offers":[{"title":"Default Title","offer_id":56894738039129,"sku":null,"price":29.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4009\/9673\/files\/SEC_5c298bef-fcd8-42cb-b5dc-f9033de6fe33.png?v=1777334628","url":"https:\/\/blocksignalling.co.uk\/products\/sec1a-dc","provider":"BLOCKsignalling","version":"1.0","type":"link"}
