Description

The Allen-Bradley 1746-ITV16 is a high-performance DC sourcing input module designed specifically for the Allen-Bradley SLC 500 modular hardware platform. Engineered for time-critical automation applications, this digital input module delivers rapid response times and reliable signal processing in demanding industrial environments. It features 16 discrete input channels operating within a 10 to 30 VDC voltage range, making it exceptionally well-suited for fast-switching machinery, high-speed counting, and precision event tracking.

Equipped with front-panel LED indicators, the 1746-ITV16 provides immediate, clear visual feedback on the operational status of each individual I/O point for simplified troubleshooting and diagnostics. Field wiring is streamlined via removable terminal blocks featuring self-lifting pressure plates that securely accommodate up to two 14 AWG conductors, or it can be rapidly integrated using compatible Bulletin 1492 interface modules and pre-wired cables.

Features

• 16 discrete DC sourcing input channels for high-density industrial control architectures

• Front-panel LED status indicators for real-time per-point diagnostics
• Self-lifting terminal pressure plates accepting dual 14 AWG wires per connection point
• Seamless backplane power integration drawing 85mA at 5VDC and 0mA at 24VDC
• Directly compatible with SLC 500 chassis racks and Bulletin 1492 pre-wired interface solutions

Applications

• High-speed manufacturing and packaging machinery
• Conveying and sorting material handling systems
• Discrete component assembly lines
• Time-critical event logging and pulse detection
• General industrial automation and process control panels

Technical Specifications

Connections / Interfaces

• Backplane Connection: Direct slot-insertion into any standard SLC 500 modular chassis.
• Field Wiring Terminals: Removable terminal block with self-lifting pressure plates (accepts up to two 14 AWG / 2 mm squared wires per terminal).
• Alternative Cabling: Supports Bulletin 1492 interface modules via pre-wired swing-arm cable connections.

Installation Guidelines

• Always disconnect power to the SLC 500 chassis and associated field wiring before installing or removing the 1746-ITV16 module.
• Verify that backplane power supply capacity is adequate to support the module current draw of 85mA at 5VDC.
• Secure module retaining screws firmly to ensure reliable chassis grounding and backplane engagement.
• Route low-level DC signal wiring away from high-voltage AC lines and variable frequency drives to prevent electrical noise interference.
