# PX-149 digital input module CAD drawings for PX-149 help place the selected digital input module and coordinate its mounting, connection access and service space. A digital input module reports discrete conditions such as a switch being open or closed. The selected wiring and electrical data establish how each input is supplied and referenced. ## Equipment and file summary Equipment / resource: PX-149 digital input module Manufacturer: AutomationDirect Resource type: Named drawing reference Listed file formats: DWG Listed files: 2 Available previews: Manufacturer source / drawing request Recorded revisions: Confirm the revision with the manufacturer Source checked: 2026-10-13 Download access: Use the official manufacturer source or request the exact drawing ## Related GA references - [AutomationDirect Protos X Field I/O](https://eloragrid.ai/objects/automationdirect-protos-x-field-i-o) - [AutomationDirect PX-149 digital input module](https://eloragrid.ai/objects/ga-px-149-98003354e660) - [PLC CPU module](https://eloragrid.ai/objects/ga-plc-cpu-module) - [HMI touchscreen](https://eloragrid.ai/objects/ga-hmi-touchscreen) Canonical page: https://eloragrid.ai/tools/cad-library/equipment/drawing-px-149-98003354e660 Manufacturer: AutomationDirect Entry type: Named drawing reference Part number: Not specified — select exact configuration Category: Automation & controls Formats: DWG Market discovery: US / Global Access: Direct download Official source: https://support.automationdirect.com/docs/drawings.html Manufacturer evidence: https://support.automationdirect.com/docs/drawings.html Source checked: 2026-10-13T00:00:00.000Z Original CAD is retained privately; explicit publisher restrictions keep public downloads on the official route. Use Request CAD for exact variants. US and Canada supplier catalogue; globally discoverable. Regional suitability must be verified for exact part. The verified native member is Other PLC Products/Protos X IO/PX-149.dwg. Its identity was checked against the acquired manufacturer archive. Coordinate the field-I/O assembly and its cable approach, then map the selected hardware to the control drawing. The drawing is a mechanical coordination reference, not a circuit design or certification record. Associated drawing identities with matching non-text geometry or explicit voltage/view aliases are grouped here: PX-249. Grouping does not establish electrical interchangeability. ## In plain English ### What the equipment does An input module brings measurements or on/off signals from equipment into a controller so its program can respond. ### A simple example In a substation control panel, an input module can report whether a breaker is open or closed. ### What the drawings help you do The verified native member is Other PLC Products/Protos X IO/PX-149.dwg. Its identity was checked against the acquired manufacturer archive. Coordinate the field-I/O assembly and its cable approach, then map the selected hardware to the control drawing. The drawing is a mechanical coordination reference, not a circuit design or certification record. Associated drawing identities with matching non-text geometry or explicit voltage/view aliases are grouped here: PX-249. Grouping does not establish electrical interchangeability. ### Before using this reference - Confirm that the project schedule calls for PX-149 or an explicitly documented associated drawing identity. - Coordinate the field-I/O assembly and its cable approach, then map the selected hardware to the control drawing. - Check the units and drawing revision before measuring or inserting geometry into a project. - Map the shown hardware to the intended station position, terminal approach and control drawing; reserve access to ports and removable terminals. - Verify ratings, compatible accessories and installation clearances using the manufacturer documentation for the exact device. ### What does the PX-149 reference verify? It verifies the acquired native drawing identity and its place in the official Protos X field-I/O hardware source collection. The source member and checksums identify the reviewed file; they do not establish the selected device rating or current revision. ### How should I use the original file? Download the unchanged manufacturer archive from the official route and locate Other PLC Products/Protos X IO/PX-149.dwg. Check the drawing units and revision before using its geometry in the project. ### Can grouped drawing identities replace one another electrically? No. Mechanical drawing grouping only avoids separate pages for matching geometry, views or voltage aliases. Confirm exact electrical function, connection arrangement and manufacturer compatibility separately. ### Terms - CAD: Computer-aided design files used to prepare drawings and models. - Revision: The recorded version of a drawing or model.
