Welcome to Rossonix Co., Limited – your trusted partner for high-quality industrial automation components since 2011. With an annual export value exceeding US$5 Million and a dedicated team of 11–50 professionals, we proudly serve global markets including North America, Europe, Oceania, and beyond. Our 1746-IH16 Allen Bradley SLC500 System Input Module is a genuine, factory-tested solution designed to deliver reliable performance in demanding PLC control environments. Whether you are upgrading an existing SLC500 system or replacing a faulty unit, this module combines proven engineering with exceptional value.
The 1746-IH16 (also known as 1746IH16) is a 16-point AC input module specifically designed for the Allen Bradley SLC500 programmable logic controller family. It accepts 120VAC or 240VAC input signals, making it ideal for discrete sensing applications such as limit switches, push buttons, and proximity sensors. Each input is optically isolated for enhanced noise immunity and safety, ensuring stable operation even in electrically harsh environments. The module mounts directly into any SLC500 chassis and communicates seamlessly with the processor via the backplane.
Key Features & Technical Specifications
- 16 AC Input Points – Provides 16 independently isolated input channels for maximum flexibility.
- Wide Voltage Range – Accepts 120VAC (±15%) or 240VAC (±15%), 50/60 Hz.
- Optical Isolation – Each channel is optically isolated (1500VAC) to protect the controller from surges.
- LED Indicators – Front-panel LEDs indicate the state of each input for easy diagnostics.
- Hot-Swappable – Can be inserted or removed while the system is powered (subject to system design).
- Compact Form Factor – Occupies a single slot in the SLC500 chassis.
- Compliance – Manufactured under ISO9001:2015 quality management system by Rockwell Automation.
