ATC-108 RS-232/RS-422/RS-485 optical isolation interface converter is a product compatible with RS-232C, RS-422 and RS-485 standards. It can convert single-ended RS-232 signals to balanced differential RS-422 or RS-485 signals. The built-in optocoupler and DC/DC converter can provide 3500V isolation voltage, and the fast transient voltage suppressor (TVS) can effectively suppress lightning (Lightning) and ESD. It provides 600W surge protection per line and can effectively prevent lightning and common-mode interference.
The ATC‑108 optical isolation interface converter supports RS‑232, RS‑422 and RS‑485 standards, converting single‑ended RS‑232 signals to balanced differential RS‑422/RS‑485 signals. It includes built‑in optical isolation and a DC‑DC converter that can provide up to 3500 V isolation voltage and TVS protection for lightning and ESD.
The device offers flexible connection options, supporting point‑to‑point and point‑to‑multi‑point networks (up to 32 devices), with data rates from 0 to 115.2 kbps. Installation is straightforward: connect the RS‑232 DB9 connector to a PC or IPC, and use the screw‑type terminal blocks for RS‑422/RS‑485 connections. The manual also covers power supply requirements, wiring diagrams, and troubleshooting steps. This manual is written in Chinese.
