GSM-Based Remote Digital I/O Controller

Product Overview

The Remote Digital I/O Controller is an innovative GSM-based electronic device designed to enable seamless remote monitoring and control of digital inputs and outputs. Leveraging the reliability of GSM (Global System for Mobile Communications) technology, this compact and versatile product allows users to interact with connected devices from anywhere in the world via SMS, voice calls, or data connections. Ideal for IoT applications, industrial automation, and home security systems, it bridges the gap between physical hardware and mobile connectivity, ensuring real-time responsiveness and ease of integration.

Whether you're monitoring sensor data from a remote site or activating relays to control machinery, this controller provides a robust solution for digital signal management without the need for complex wiring or on-site presence.

WKey Features

  • GSM Connectivity: Supports quad-band GSM modules (850/900/1800/1900 MHz) for global compatibility.

  • Digital Inputs: Up to 4 configurable digital inputs (e.g., dry contacts or voltage levels from 0-240V AC or DC ) for detecting events such as door openings, motion sensors, or switch states. Inputs are optically isolated to prevent noise interference and support debounce functionality for reliable signal detection.

  • Digital Outputs: Up to 4 relay-based outputs (rated at 7A/250V AC or 10A/125V AC or 10A/30V DC) for controlling devices like lights, pumps, alarms, or motors. Outputs can be toggled remotely or automated based on input triggers.

  • Microcontroller Core: Powered by a high-performance ARM-based microcontroller with embedded firmware for efficient processing, event logging, and customizable logic rules.

  • Power Management: Operates on a wide input voltage range (5-24V DC) or (110-220V AC)with low power consumption.

  • User Interface: LED indicators for status monitoring and a built-in buzzer for local alerts.
