Two logic inputs are available: Terminal 1 activates when pulled to ground, and Terminal 3 activates with a positive voltage from 3.3 to 24 Vdc. Each pulse is provided as single-pole relay contacts rated 60 W (2 A) and as an open-collector output at 25 mA for indicators or slave relays. The module requires ground-referenced 24 Vdc at 100 mA, such as from the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003eRDL PS-24AX\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart and end pulses\u003c\/strong\u003e — One control signal produces separate pulses when it begins and ends.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive high or low inputs\u003c\/strong\u003e — Inputs accept ground closures or 3.3 to 24 Vdc logic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay and open-collector outputs\u003c\/strong\u003e — Each pulse is available as contacts and as an open-collector output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch or logic control\u003c\/strong\u003e — Pushbuttons, switches or logic circuits can drive the module.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":68025796493548,"sku":"ST-LCR3","price":182.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/st-lcr3.jpg?v=1793583957","url":"https:\/\/creationnetworks.net\/products\/rdl-st-lcr3","provider":"Creation Networks","version":"1.0","type":"link"}
