Product Description P/N: 1771-IA
Description
The Allen-Bradley 1771-IA is an 8-channel discrete input module for PLC-5 controllers, supporting both 120 VAC and 125 VDC input signals. It conditions field-level on/off signals and transfers their logic state to the CPU for processing. The module uses a 1771-WA wiring arm for field termination and installs in a single slot of a 1771 I/O chassis.
Technical Specifications
Information About 1771-IA
The 1771-IA belongs to the Allen-Bradley PLC-5 I/O family and provides eight optoelectronically isolated AC/DC input channels operating within the 120 V class. Its construction incorporates input filtering and signal conditioning circuitry to ensure proper detection of on/off transitions from devices such as limit switches, contacts, and pushbuttons. The module integrates into any 1771 chassis slot, provided adequate power supply capacity is available, and supports standard PLC-5 addressing methods. Typical applications include interfacing to machine-level status devices, where reliable AC/DC signal sensing and compatibility with legacy PLC-5 systems are required.
Key Features:
- Eight Discrete Input Channels: Accepts AC or DC signals at 120 VAC or 125 VDC levels.
- Optoelectrical Isolation: Protects backplane electronics from field-side transients.
- Input Filtering: Helps eliminate electrical noise for stable input detection.
- Wide Input Voltage Range: Operates at 87–138 VAC and 97–138 VDC for flexible field wiring.
- 1771-WA Wiring Arm Compatible: Provides modular field termination for quick replacement.
- Defined Signal Timing: Offers predictable AC and DC on/off signal delays.
- Single-Slot PLC-5 Installation: Fits any compatible 1771 chassis with 75 mA backplane current draw.
- Front-Panel Indicators: Includes status LEDs for each input channel.
The 1771-IA delivers the reliability and precision required for discrete signal monitoring in PLC-5 industrial control systems.
