Description

Product Overview

The Allen-Bradley 1746-IG16 is a high-speed 16-point digital TTL input module designed for the SLC 500 programmable logic controller system by Rockwell Automation. Operating with a 5V DC TTL sourcing configuration (+4.5V to 5.5V DC range), this module features inverted logic functionality (-0.2 to 0.8V DC corresponds to an ON state) for direct interfacing with Transistor-Transistor Logic signals and high-speed sensors. Equipped with a Removable Terminal Block (RTB) for simplified wiring and maintenance, the module consumes 0.140A (140 mA) at 5V DC backplane current while featuring a net weight of 0.3 kg.

Key Advantages

  • Direct TTL Signal Compatibility: Formatted specifically for 5V DC TTL sourcing inputs (+4.5V to 5.5V DC) without requiring external signal conversion interface hardware.
  • Ultra-Fast Response Times: Delivers rapid high-speed signal detection with a maximum signal delay of 0.25 ms (ON) and 0.50 ms (OFF) for fast-acting control processes.
  • Integrated Inverted Logic Support: Built-in inverted logic handling ensures reliable communication with standard TTL low-voltage logic outputs (-0.2 to +0.8V DC = ON).
  • Removable Terminal Block (RTB): Streamlines system installation, troubleshooting, and field module replacement without disconnecting underlying wiring arrays.
  • Compact Physical Profile: Lightweight 0.3 kg footprint engineered for energy-efficient integration into standard SLC 500 rack chassis slots.

Frequently Asked Questions

Q1: What signal logic does the 1746-IG16 module use?

A1: The module uses inverted logic for standard 5V DC TTL signals, where a low voltage (-0.2V to +0.8V DC) represents the ON state.

Q2: What is the backplane power requirement for the 1746-IG16?

A2: It consumes 0.140A (140 mA) at 5V DC and 0.0A at 24V DC from the SLC 500 chassis backplane.

Q3: What are the input signal response times for this module?

A3: The 1746-IG16 features maximum signal delay times of 0.25 ms for turn-ON and 0.50 ms for turn-OFF.
