{"product_id":"automation-direct-d2-rmsm-i-master-module","title":"Automation Direct D2-RMSM I Master Module","description":"\u003cdiv\u003eThe Automation Direct D2-RMSM Serial Remote I\/O Master Module is a DirectLogic DL205 accessory that serves as the remote I\/O master in a RM‑NET\/SM‑NET network, enabling expansion of a DL205 system’s I\/O through remote slave modules. It is designed to work with D2‑RSSS remote slave modules to extend input\/output capability beyond the CPU’s native I\/O, while the remote master maintains its own diagnostics and memory for autonomous operation. The module includes rear-panel DIP and rotary switches for configuring baud rate and addressing, enabling precise network setup and addressing within a DL205 system. Official listings show UL file E157382 and CSA file 234884, with RoHS status listed as No. This item is a retired, discontinued product (withdrawn 04\/2015) and has no direct replacement in AutomationDirect’s current catalog. In typical DL205 configurations, multiple remote masters can be used to scale I\/O, with a documented example indicating up to 896 I\/O points available when using two remote masters with seven slaves per module. This makes the D2-RMSM a historical but relevant option for legacy DL205 installations or retrofits that rely on RM‑NET\/SM‑NET remote I\/O expansion.\u003c\/div\u003e","brand":"AutomationDirect","offers":[{"title":"New","offer_id":51660382044462,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b54281dc-d570-418a-8bf6-3ec5a20accd1.jpg?v=1769537109","url":"https:\/\/plgautomation.com\/products\/automation-direct-d2-rmsm-i-master-module","provider":"PLG Automation ","version":"1.0","type":"link"}
