Information About 1771-ID16
The 1771-ID16 is part of Rockwell Automation’s 1771 Universal I/O family and is designed to interface discrete AC/DC field devices with PLC-5 controllers. It provides 16 individually isolated input channels, ensuring electrical separation between incoming signals to enhance safety and noise immunity in multi-phase or high-noise environments. The module features built-in filtering to suppress contact bounce and transient spikes, with a 9 ms factory-set filter suitable for most industrial applications. It installs in standard 1771 chassis such as the 1771-A1B or 1771-A4B and uses the 1771-WN wiring arm for quick field wiring and easy RIUP (Removal and Insertion Under Power). Designed for long-term reliability, the 1771-ID16 supports high switching frequencies and is commonly used with limit switches, float switches, selector switches, annunciators, and similar ON/OFF devices.
Key Features:
- 16 Isolated Inputs: Accepts sixteen 120V AC/DC signals, each electrically separated for enhanced safety and noise immunity.
- Reliable Signal Filtering: Includes factory-set 9 ms filtering to suppress noise, contact bounce, and transient disturbances.
- Fast Response Times: Provides typical 1 ms ON delays and 9–18 ms OFF delays depending on AC or DC input.
- PLC-5 System Compatibility: Fits all 1771-series I/O chassis and supports RIUP for maintenance without disconnecting wiring.
- Robust Field Connectivity: Uses the 1771-WN wiring arm for secure screw-terminal connections and simplified module replacement.
- Industrial-Grade Performance: Rated for 0–60 °C operation, meeting global compliance standards including UL, CE, CSA, and Marine.
- Broad Application Range: Suitable for safety functions, machine controls, pilot devices, limit switches, and annunciator panels.
- Durable Construction: Built to handle millions of switching operations in harsh industrial environments.
The 1771-ID16 delivers the reliability and precision required for accurate digital input processing in PLC-5 automation and safety-critical control systems.
