This plug-and-play system supports both common-anode or common-cathode signals giving you the capability of modeling a variety of different prototypical scenarios.\u003c\/p\u003e\n\u003cp\u003e• Stand Alone Operation - in this case a single signal runs independently of other signals, and displays appropriate aspects, such as red - yellow - green, in a timed manner.\u003cbr\u003e• Integrated ABS Block Signaling - Connecting a number of Signal Control Boards together in a daisy chain fashion enables you to represent a prototypical block signal system, where the occupancy of the blocks ahead and behind your train determines the aspects displayed by the signals. The number of blocks is controlled by a simple jumper setting on each signal control board.\u003cbr\u003e• Approach-Only Signaling - To better support prototypes whose signals do not illuminate until a train is nearby, the Signal Control Board has a setting to enable this behavior.\u003c\/p\u003e","brand":"Atlas Model Railroad","offers":[{"title":"Default Title","offer_id":47986321653985,"sku":"ATL70000046","price":27.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/8993\/files\/zx5irxqkoopbca6bas6p.jpg?v=1771464017","url":"https:\/\/www.tammieshobbies.com\/products\/atlas-ho-n-universal-signal-control-board","provider":"Tammies Hobbies","version":"1.0","type":"link"}
