Information About 1771-ID16
The 1771-ID16 belongs to the Allen-Bradley 1771 Universal I/O family, developed to interface discrete devices with PLC-5 processors. It supports 16 individually isolated inputs at 120V AC/DC and is designed with input filtering to suppress noise and voltage transients caused by contact bounce. The module has a factory-set filter time of 9 ms, with typical delays of 9–18 ms for AC on/off transitions and 0.57 ms for DC switching. It installs in a 1771 I/O chassis such as the 1771-A1B or 1771-A4B and uses the 1771-WN wiring arm for secure field connections. Built for isolated multi-phase applications, the 1771-ID16 is suitable for interfacing with limit switches, float switches, selector switches, and pushbuttons. Its modular design allows hot-swapping (removal and insertion under power) without rewiring, making it practical for demanding industrial environments.
Key Features:
- Design: 16-channel digital input module with isolated 120V AC/DC inputs.
- Input Filtering: Customer-selectable filters suppress noise and voltage transients, improving reliability.
- Performance: Factory-set filter time of 9 ms with 9–18 ms AC delay and 0.57 ms DC delay.
- Compatibility: Operates with PLC-5 controllers in 1771 I/O chassis (e.g., 1771-A1B, 1771-A4B).
- Connectivity: Uses 1771-WN wiring arm for quick connections and easy module replacement.
- Durability: Designed for long service life with support for millions of switching operations.
- Application Range: Interfaces with ON/OFF devices such as pushbuttons, limit switches, pilot lights, annunciators, and motor starters.
- Ease of Maintenance: Supports removal and insertion under power (RIUP) without disconnecting field wiring.
The 1771-ID16 delivers the robustness and reliability required for industrial digital input applications in PLC-5 automation systems.
