Description
Grayhill Digital AC Input Module
Model: 70G-IAC24 | G5-Style Optically Isolated | 120 VAC Input to 24 VDC Logic
Used Condition
— Clean industrial pull. Retaining pin and plug-in terminals are fully verified for reliable panel re-deployment.
Product Overview
The genuine Grayhill 70G-IAC24 is an industrial-grade, G5-style digital AC input module engineered to safely sense high-voltage field signals and convert them into clean logic commands. This robust component isolates and monitors 120 VAC control loops from limit switches, pushbuttons, or relays, translating them into standard 24 VDC inputs compatible with PLCs, single-board computers, and custom automated control systems. Featuring premium optical isolation, it blocks high-voltage transients, electrical surges, and line spikes from feeding back into sensitive logic arrays.

Key Features & Operational Benefits
- Industrial-Grade Noise Immunity: Built-in filtering networks ensure the logic side ignores standard line harmonics and inductive switching chatter from big motors or contactors.
- True G5 Compact Form Factor: Features a streamlined layout compared to older, bulky modules, maximizing channel counts per linear foot of panel space.
- Integrated Captive Screw: A robust, built-in retention screw locks the module firmly onto the host rack to prevent loose connections in high-vibration machinery environments.
- Fast, Reliable Diagnostics: Designed for clear interfacing, providing an effortless plug-and-play avenue to service individual processing lines without rewiring fields.
Logistics & Seller Support
Secure Anti-Static Dispatch: This module is meticulously packed in a protective ESD anti-static bag and padded within an outer structural box to completely preserve its optical internal paths and gold-plated header pins during transit. Tracked freight is initiated immediately.
