RS485 Hub COMMFRONT Opto‑Isolated Industrial

Description

Product Overview

The COMMFRONT RS485 Hub is a rugged, industrial‑grade, opto‑isolated splitter designed for demanding networking environments. Housed in a compact 7.91 x 5.98 x 2.09 inch enclosure weighing just 13.6 ounces, it delivers 2500V optical isolation, 15kV static protection, and a built‑in 600W surge protector. It auto‑senses and self‑adjusts across a wide baud range of 300 to 115.2K, supporting multi‑drop RS485 networks of up to 512 nodes (4×128) with reliable data integrity.

Usage

Ideal for factory automation, process control, and heavy‑duty field deployments, this hub thrives in environments with high electromagnetic interference and voltage transients. It connects PLCs, sensors, and HMIs across expansive networks, ensuring uninterrupted communication even in harsh conditions.

FAQ

What is the maximum number of nodes supported?

The hub can handle up to 512 nodes, organized as four groups of 128 devices each.

How does the optical isolation protect my network?

Optical isolation separates the data signal from high voltage transients, preventing damage from spikes up to 2500V and static discharges up to 15kV.

Can I expand the network beyond 512 nodes?

Yes, by linking additional HUB‑485‑4 units you can extend the system while maintaining isolation and protection.

What baud rates does the hub support?

It automatically detects and adjusts to any baud rate between 300 and 115.2K, ensuring compatibility with a wide range of devices.

Is the hub suitable for outdoor installations?

While the hub is designed for industrial indoor use, its robust protection makes it capable of handling outdoor environments when housed in a suitable enclosure.
