Beskrivelse
Product Overview
The 1734-IA4 is a compact, high-density 120 VAC Discrete Input Module manufactured by Allen-Bradley (Rockwell Automation) as part of the flexible POINT I/O System. Engineered for distributed automation architectures, this module provides Four (4) non-isolated, sinking input channels designed to convert 120 VAC discrete field signals into logic-level data for host processors. Operating across an external input supply range of 85 to 132 VAC (47–63 Hz), it mounts directly onto standard terminal bases such as the 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS wiring base assemblies. Featuring a lightweight hardware net weight of 30.9 g (0.0309 kg / 1.09 oz) and key switch position 8, this open-style module offers high-density channel monitoring with an exceptionally low POINTBus backplane current draw of 75 mA at 5V DC.
As illustrated in the product image, the module showcases a ultra-slim, vertical slice design equipped with individual LED status indicators for Module, Network, and channel-level I/O activity, allowing intuitive, real-time diagnostic visibility.
Core Technical Advantages
- Ultra-Compact POINT I/O Footprint: Highly space-efficient slice design allows high-density field wiring in constrained control enclosures, supporting both horizontal and vertical mounting orientations.
- Robust Field-to-System Isolation: Rated for 240V continuous isolation (type-tested at 3250V DC for 60 seconds), protecting system-side backplane electronics from field-side voltage transients.
- Clear Channel Status Diagnostics: Individual yellow status LEDs replicate field input energization state, alongside dedicated visual LEDs for overall Module Status (MS) and Network Status (NS).
- Keyed Terminal Base Insertion: Configured for Mechanical Key Switch Position 8, preventing accidental insertion of incorrect module types into designated wiring bases during field maintenance.
