The unit occupies two module widths on standard 35mm DIN rail and provides a volt-free 16A changeover contact for switching loads up to 3,680W at 230V. The astro function automatically adjusts switching times based on sunrise and sunset, removing the need to reprogram seasonal time changes for outdoor lighting or security applications.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, industrial and residential installations requiring automated lighting or equipment control, the 72101 stores up to 60 switching events across a 7-day programme. The LCD display shows current time, day, programme status and next switching event, with simple front-panel button programming. The changeover contact configuration allows the switch to control normally-open or normally-closed circuits, making it suitable for fail-safe applications where the load must default to a specific state on power loss.\u003c\/p\u003e\n\u003cp\u003eThe 10-year battery reserve maintains programme memory and timekeeping during mains power interruptions, eliminating the need to reprogram the unit after outages. The 72101 is compatible with Sangamo's optional key programming accessory and EasyVUE remote monitoring hub, allowing faster bulk programming across multiple installations and real-time status checking via network connection. The compact 108 x 43 x 65mm housing fits alongside MCBs and other DIN rail components in tight panel layouts.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.165\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e1.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e108\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e43\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e223\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e146\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_72101_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_72101-72201.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the astro function do?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe astro function automatically calculates sunrise and sunset times based on the configured location and date, then adjusts switching events relative to those times.
