Produkt-Beschreibung
Allen Bradley 1771-IA/C Discrete Input Module
The 1771-IA/C is an 8-point discrete input module specifically designed for Allen-Bradley's PLC-5 architecture. This module serves as the primary interface for 120V AC or 125V DC field signals, converting physical states into binary logic for the processor. Installed directly in the 1771 universal I/O chassis, it consumes only 75mA from the backplane. The Series C revision is renowned for its sustained reliability in legacy systems, handling sensing applications from basic pushbuttons to complex limit switch arrays with minimal power requirements.
Engineered for industrial environments with high electromagnetic interference, the 1771-IA/C maintains signal integrity through internal opto-electrical isolation. This technology decouples sensitive backplane electronics from field-side transients. Each of the eight channels includes hardware-based filtering to eliminate contact bounce and inductive noise common in aging wiring systems. Front-facing orange neon indicators provide immediate visual confirmation of input status, facilitating quick troubleshooting during shift changes. The module operates reliably across voltage ranges from 87V to 138V.
Maintenance efficiency is enhanced through compatibility with the 1771-WA wiring arm, enabling technicians to replace modules without disturbing field wiring. This design significantly reduces Mean Time to Repair when unit failures occur. No recalibration or complex mapping is required—it's a drop-in replacement that maintains timing precision for motor starter auxiliary contacts and interlocking logic. For facilities relying on PLC-5 systems, this module provides a rugged, proven solution to maintain legacy control loops without signal dropouts or hardware fatigue.
