Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The TM171DWAL2L is a Schneider Modicon M171 remote display module, order code TM171DWAL2L, featuring a monochrome backlit LCD screen with 4 keys and a real-time clock. It operates from an external 12 V supply and is rated IP40 for indoor panel mounting. This display is designed for use with Modicon M171 optimized logic controllers, providing local operator interface and status indication via the LCD. The part is now discontinued by Schneider. The TM171DWAL2L presents a monochrome backlit LCD screen for displaying text and basic graphics from the connected M171 logic controller. Four front-panel keys allow operator navigation and parameter adjustment without a separate HMI. An integrated real-time clock enables time-stamped events and scheduled control actions. The module draws power from an external 12 V source — not from the controller backplane — so it can be mounted remotely up to the cable length limit. ## Applications This display module is typically used as a wall-mounted or panel-mounted operator interface for Modicon M171 optimized logic controllers in HVAC, lighting control, and building automation systems. It provides local readout of setpoints, temperatures, and alarms without a full HMI panel.","metaTitle":"Schneider TM171DWAL2L Modicon M171 Display Module, Monochrome LCD","metaDescription":"Schneider Modicon M171 TM171DWAL2L remote display: monochrome backlit LCD, 4 keys, real-time clock, external 12 V supply, IP40, discontinued.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Color":"White","Depth":"1.2 in (31.3 mm)","Width":"3.8 in (96.5 mm)","Height":"5.4 in (137 mm)","Supply":"External source","Marking":"CE","Category":"US1PC1222537","Display Type":"Backlit LCD screen","Number of key":"4","Display colour":"Monochrome","Realtime clock":"With","lifecycle_stage":"current","Local signalling":"LCD display","Range of Product":"Modicon M171","Nbr. of units in pkg.":"1","Power Consumption in W":"0 W 5 W","IP degree of protection":"IP40 front face:","Product or Component Type":"Display module","[Us] rated supply voltage":"12 V DC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$113.65 – $124.09","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7eec0e4eb1acd221945f08fe414959e4.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/TM171DWAL2L/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/TM171DWAL2L","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/TM171DWAL2L when reusing this data.
