Description

Product Overview

The Allen-Bradley 1794-IC16 is a Flex I/O digital input module featuring 16 nonisolated sinking input channels operating at a nominal 48V DC. Designed by Rockwell Automation, this compact DIN-rail or screw-mounted module expands distributed PLC I/O capacity, providing high noise immunity and flexible signal filtering for demanding industrial control applications.

Core Features

  • 16 High-Density Sinking Inputs: Accepts up to 16 48V DC sinking inputs to monitor field sensors, switches, and discrete devices.
  • Configurable Filter Times: Input filter response times can be configured in software to adapt to noisy process signals and contact bounce.
  • Visual Status Diagnostics: Equipped with 16 individual logic-driven yellow LEDs for clear channel-level input status identification.
  • High Isolation Protection: Designed to withstand up to 1900V DC isolation testing to safeguard Flexbus backplane communication lines.

Engineering & Installation Guide

  • Keyswitch Alignment: Rotate the terminal base keyswitch to Position 2 before inserting the 1794-IC16 module to ensure proper electrical matching.
  • Terminal Base Wiring: Wire input signal lines to designated numbered terminals on compatible bases like the 1794-TB3S or 1794-TB3SK, matching individual sensor channels accurately.
  • Power Protection: Install surge suppression on field power supply lines to prevent voltage spikes from damaging input circuit resistors.
  • Enclosure Mounting: Mount the unit inside an IP54/NEMA-rated protective enclosure using 35mm DIN rail or panel screws to guard open-style electronics from dust and humidity.

Technical FAQs

Q1: What input voltage levels define the On-state and Off-state for the 1794-IC16?
A1: An On-state signal requires 30V to 60V DC (min 2.0 mA), while an Off-state is recognized at 10V DC max.

Q2: Which terminal base units can be used with this module?
A2: It mounts on 1794-TB3, 1794-TB3S, 1794-TB3K, and 1794-TB3SK terminal bases using keyswitch position 2.

Q3: Is the 1794-IC16 module a sinking or sourcing input module?
A3: It features 16 sinking inputs, meaning field devices switch the positive (+V DC) side of the voltage source to the input terminals.
