Information About 1756-IA16
The 1756-IA16 is part of the ControlLogix family of modular digital input solutions used for AC signal interfacing in industrial automation systems. It supports 16 channels of 120V AC input signals, divided into two isolated groups of eight, providing flexibility when wiring separate circuits. Designed with programmable filtering, the module allows users to select delay times to minimize false triggers from electrical noise or contact bounce. With channel-by-channel diagnostic LEDs, technicians gain real-time visibility into signal status, simplifying commissioning and troubleshooting. The module is compatible with 1756-TBNH and 1756-TBSH removable terminal blocks, ensuring easy installation and maintenance. Its robust design, low power consumption, and high immunity to electrical interference make the 1756-IA16 a dependable choice for diverse ControlLogix applications.
Key Features:
- Sixteen 120V AC Input Channels: Supports a full input range of 74–132V AC at 47–63 Hz, enabling reliable detection of AC signals from switches, auxiliary contacts, and relays across machine-level and process environments.
- Programmable Input Filtering: Offers user-selectable filter delays (1 or 2 ms for ON, 9 or 18 ms for OFF) that help reduce noise-induced false triggering, ensuring stable operation in electrically noisy installations.
- Channel Status LEDs: Each of the 16 inputs includes individual diagnostic indicators plus module health monitoring, enabling fast troubleshooting and clear visibility into input behavior.
- Efficient Power Consumption: Draws only 100–105 mA at 5.1V and 2 mA at 24V from the backplane, with a total dissipation of 5.8 W, making it suitable for large I/O systems with tight power budgets.
- Flexible Wiring Options: Compatible with 1756-TBNH and 1756-TBSH removable terminal blocks, allowing both screw and spring-clamp wiring while simplifying maintenance and replacement operations.
- Industrial-Grade Reliability: Designed for operation from 0–60°C with strong electrical noise immunity, meeting global industrial certifications including UL, CE, CSA, KC, and Marine ratings.
- Optimized for ControlLogix Platforms: Integrates seamlessly with all ControlLogix chassis and controllers, supporting scalable architectures for both discrete and hybrid automation systems.
- Robust Input Handling: Maintains reliable operation with ON-state currents from 5 to 13 mA and OFF-state leakage up to 2.5 mA, ensuring correct detection across a range of AC field devices.
The 1756-IA16 delivers stable, accurate, and noise-immune AC input performance, making it an essential component in ControlLogix-based automation and industrial control applications.
