Key Features

1. 16‑Channel High‑Density AC Input: Accepts 120VAC discrete signals from contactors, limit switches, and pushbuttons, reducing cabinet space and wiring complexity.
2. Grouped Input Architecture: All 16 channels share a common power group, simplifying field wiring and reducing installation time.
3. Wide Operating Voltage Tolerance: Operates reliably from 0–132VAC, accommodating voltage fluctuations in industrial power systems.
4. 2ms Hardware Noise Filtering: Suppresses electrical noise and contact bounce, ensuring stable ON/OFF state detection in electrically noisy environments.
5. 2500Vrms Isolation: Provides complete electrical separation between field AC circuits and low‑voltage logic, protecting the PLC and improving safety.
6. Enhanced “J” Revision Robustness: Upgraded surge protection, tighter component screening, and extended temperature stability ensure reliable 24/7 operation in harsh industrial conditions.
7. Real‑Time Channel Status LEDs: Individual LEDs for each input channel enable immediate visual diagnostics, reducing troubleshooting time.
8. Fault Detection & Reporting: Onboard diagnostics detect module faults, overvoltage conditions, and communication errors, reporting via LED indicators and the Field Control bus.
9. Hazardous Location Compliance: UL/CSA Class I Div 2 rated for safe operation in explosive atmospheres (oil and gas, chemical processing).
10. Seamless System Integration: Compatible with all Field Control BIUs, bases, and programming software, enabling easy integration into new or existing systems.
