Description

With automatic data collection and a built-in rule engine, ISM QUAD RF IoT Gateway can process field data locally and execute condition-based actions. At the field level, the device communicates securely with other ISM QUAD RF and compatible RF devices over a license-free 868 MHz ISM band RF network, using AES-256 encryption. This architecture enables data collection across wide and distributed field environments without dependency on SIM cards or cellular operators. Data collected over the RF network can be transmitted to SCADA systems, software applications, and IoT platforms via Ethernet or Wi-Fi connections, using MQTT, HTTP, and Modbus TCP protocols. This ensures reliable integration between the RF-based field infrastructure and IP-based central systems.

Equipped with WireGuard VPN, a built-in firewall, certificate-based authentication, and encryption features, ISM QUAD RF provides a high level of security for industrial systems requiring secure remote access and data protection over Ethernet and Wi-Fi connections.

Its industrial-grade metal enclosure, wide operating temperature range, and robust design ensure reliable, stable, and long-term operation in harsh field environments.

Fast and Easy Installation

Designed for quick commissioning, the ISM QUAD RF IoT Gateway enables fast and effortless installation in the field. In case of temporary network interruptions, the device automatically reconnects, ensuring continuous and reliable system operation.

Easy Mounting and Setup

With DIN rail mounting support, the ISM QUAD RF IoT Gateway can be installed quickly and securely in control panels. Thanks to its web-based user interface and built-in Wi-Fi Access Point capability, the device can be easily configured without the need for additional equipment.

Automatic Data Collection

The ISM QUAD RF IoT Gateway automatically reads data from connected devices and ensures that up-to-date information is delivered to the system. Periodic data polling and configurable condition-based actions help reduce unnecessary data transmission and improve overall system efficiency.
