It monitors trains entering and leaving using infra-red sensors mounted below the track and automatically controls the signal at the entrance to the block.\u003c\/p\u003e\n\u003cp data-end=\"914\" data-start=\"404\"\u003eWhen a train enters the section, the module sets the entrance signal to danger (red) and switches a short isolated approach section from DCC to DC. This causes DCC-equipped locomotives (configured to stop on DC) to decelerate realistically and come to a standstill in front of the red signal. The module then restores DCC and clears the signal once the train has left the section. For multi-aspect signalling, the module can communicate with adjacent blocks to display correct yellow and double-yellow aspects.\u003c\/p\u003e\n\u003cp data-end=\"967\" data-start=\"916\"\u003eThis version is for \u003cstrong data-end=\"966\" data-start=\"936\"\u003ecommon-cathode LED signals\u003c\/strong\u003e.\u003c\/p\u003e\n\u003chr data-end=\"972\" data-start=\"969\"\u003e\n\u003ch3 data-end=\"989\" data-start=\"974\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eMonitors trains entering and leaving a section of track using infra-red sensors.\u003cbr data-end=\"1074\" data-start=\"1071\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eAutomatically sets the signal at the start of the section to danger (red).\u003cbr data-end=\"1151\" data-start=\"1148\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eSwitches an isolated approach section from DCC to DC so DCC locomotives decelerate and stop at the signal.\u003cbr data-end=\"1260\" data-start=\"1257\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eCommunicates with previous sections so 3- and 4-aspect signals show yellow and double-yellow correctly.\u003cbr data-end=\"1366\" data-start=\"1363\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eFinal section can simulate a return to green using timers for realistic multi-aspect behaviour.\u003cbr data-end=\"1464\" data-start=\"1461\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003ePoints not set in the train’s favour can force the signal to danger and switch the isolating section to DC.\u003cbr data-end=\"1574\" data-start=\"1571\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eSignal can be forced to danger via an external input, useful for starter signals.\u003cbr data-end=\"1658\" data-start=\"1655\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eSupports 2-, 3-, and 4-aspect LED signalling and includes bidirectional running modes with 2-aspect signals.\u003cbr data-end=\"1769\" data-start=\"1766\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eIncludes additional station stop modes and an additional Dapol output.\u003cbr data-end=\"1842\" data-start=\"1839\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eCan remember occupancy status after power-off and automatically restore signals when power returns.\u003cbr data-end=\"1944\" data-start=\"1941\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2020\" data-start=\"991\"\u003eSimple to set up, with full configuration available for realistic operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"2025\" data-start=\"2022\"\u003e\n\u003ch3 data-end=\"2053\" data-start=\"2027\"\u003eElectrical Requirements\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-end=\"2086\" data-start=\"2055\"\u003eRequires a 12V DC power supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"2091\" data-start=\"2088\"\u003e\n\u003ch3 data-end=\"2121\" data-start=\"2093\"\u003eCompatibility Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-end=\"2191\" data-start=\"2123\"\u003eDesigned for DCC layouts.\u003cbr data-end=\"2151\" data-start=\"2148\"\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2191\" data-start=\"2123\"\u003eSuitable for common-cathode LED signals.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-end=\"2196\" data-start=\"2193\"\u003e\n\u003ch3 data-end=\"2224\" data-start=\"2198\"\u003eDocumentation \u0026amp; Support\u003c\/h3\u003e\n\u003cp data-end=\"2445\" data-start=\"2226\"\u003eFor detailed information on installation, wiring, programming, and troubleshooting, please download the latest instruction manual:\u003c\/p\u003e\n\u003cp data-end=\"5025\" data-start=\"4806\"\u003e\u003ca rel=\"noopener\" title=\"SEC4\" href=\"https:\/\/drive.google.com\/file\/d\/1Z04p-pu0pSO3LOnptv23V5kVqFv3ydCv\/view?usp=sharing\" target=\"_blank\"\u003eProduct Instruction Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"BLOCKsignalling","offers":[{"title":"Default Title","offer_id":56894712349017,"sku":null,"price":29.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4009\/9673\/files\/SEC_9a04a3af-28aa-4b12-873e-e84ae02e81d0.png?v=1777334661","url":"https:\/\/blocksignalling.co.uk\/products\/sec4a-dcc","provider":"BLOCKsignalling","version":"1.0","type":"link"}
