RS-232 to RS-422/485 Photoelectric Isolation Converter

The DZC-ATC-105 Photoelectric Isolation Converter is compatible with the RS-232C, RS-422, RS-485 standards and is capable of converting a single end RS-232 signal into RS-422 or RS-485.

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

Connects to a PC via a DB9 female connector at the RS-232 side, and connects on the RS-422 or RS-485 via a 4 port terminal block.

The DZC-ATC-105 Photoelectric Isolation Interface Converter can provide connections for point to point and point to multi-point communications. The point to multi-point allows the connection of 32 RS-422 or RS-485 interface devices with data transmission speeds up to 115.2KBPS.

Three LEDs indicate data flow and power availability.

DZC-ATC-107

The DZC-ATC-107 is a bi-directional interface converter. It optically isolates and converts unbalanced, full or half-duplex RS-232 signals to Optically isolated, balanced, full or half duplex RS-422 or RS-485 signals at baud rates up to 115.2 kbps.

This units also surge suppress the RS-422/485 lines. They feature Send Data Control circuitry so no software control of handshake lines is required in RS-485 mode. The DZC-ATC -107 has built-in isolators for high voltage (2500V) protection.

It provides Point-to-Point, Multi-drop and Simplex Operations.

It is powered from a DC 9V to 12V, 200mA power supply. Slide switches are used to configure its operation mode.

One LED flashes Red when sending data and green when receiving.
