RS232 to RS485/RS422 Industrial Class Photoelectric isolated Converter

The DZC-ATC-107N Photoelectric Isolation Interface Converter is compatible with the RS-232C, RS-422, RS-485 standards and capable of converting a single end RS-232 signal into RS-422 or RS-485.

The built in photoelectric isolator offers a 3500V isolation voltage and the rapid Transient Voltage Suppressor (TVS) can effectively protect against lightning and ESD. It provides 600W lightning strike and surge protection on each line.

Connects to a PC via a DB9 female connector at the RS-232 side, and connections on the RS-422 or RS-485 end via a convenient 7-port plug-in terminal.

The DZC-ATC-107N Photoelectric Isolation Interface Converter can be used for point to point or point to multi-point communications. The point to multi-point allows the connection of up to 128 devices on the RS-422 or RS-485 networks with data transmission speed of up to 115.2KBPS.

LED indications are available for power supply availability and communication flow.

An external power supply of 9-24VDC is required to power the RS485/422 side while the RS232 side is powered by the communications port. All handshaking lines have to be connected to the RS232 port.


RS-422/485 Industrial Class Photoelectric Isolation Data Repeaters


The DZC-ATC-109N is an industrial RS422 or RS485 data repeater. The photoelectric isolator and DC/DC module provides the network with 3500V Isolation voltage protection. This can prevent damage from lightning strikes.

The High efficiency lightning protection tube can effectively protect against lightning and ESD and offers up to 100W surge protection.

It has a full metal housing, anti-static and powerful anti-jamming capacity.

Suitable for point to point and point to multi-point communications.
