IOT9024DIProduct Overview
The DTECH IOT9024DI is an industrial-grade 4-port isolated RS-485 hub designed to expand one RS-485 input into four RS-485 output channels. With independent channel isolation, high-speed communication up to 5 Mbps, and a compact DIN-rail-mountable design, it helps system integrators build organized and robust serial communication networks for industrial equipment and automation systems.
The device is suitable for applications where multiple RS-485 devices need to communicate with a host controller, such as PLC-based systems, instrumentation, meters, sensors, and industrial control equipment. Confirm the wiring topology, baud rate, cable type, and network length for each installation.

Key Features
• 1 RS-485 input to 4 RS-485 output channels
• Independent isolation between RS-485 channels, as described in the supplied product material
• Communication rates from 300 bps up to 5 Mbps
• 5000 Vrms isolation rating stated in the supplied material
• Supports transmission distances up to 1.2 km at 115200 bps under the stated product conditions
• Wide-range DC 9–36 V power input
• DIN 35 mm rail mounting
• Industrial operating temperature range: -40°C to +85°C
• Compact housing: 64.5 × 27 × 90.5 mm (L × W × H)

One Input, Four Output Channels
The IOT9024DI distributes an RS-485 connection from a host device to four output branches. Each output can connect to a compatible RS-485 device or downstream segment, helping simplify wiring and network expansion. Check the device manual and the electrical requirements of connected equipment before deployment.
High-Speed Serial Communication
The product material specifies communication rates up to 5 Mbps. The stated transmission-distance reference is up to 1.2 km at 115200 bps. Actual achievable distance depends on baud rate, cable characteristics, topology, termination, electromagnetic conditions, and connected devices.
Isolation and Industrial Protection
The supplied material describes 5000 Vrms isolation and protection features intended for industrial environments. Isolation can help reduce the impact of potential differences and electrical disturbances between connected sections of a serial network. For final engineering selection, consult the official datasheet for test methods, isolation configuration, surge/EFT ratings, and installation requirements.
Typical Applications
• PLC and industrial automation communication
• Multi-device RS-485 instrumentation networks
• Industrial meters, sensors, and monitoring equipment
• Factory control cabinets and equipment integration
• Serial communication network expansion
