Industrial RS485 / RS422 Isolator / Repeater / Converter

Industrial RS485 / RS422 Isolator / Repeater / Converter

Model: RPT-485_422-4

The RPT-485_422-4 is a rugged, industrial-grade, optically-isolated RS485 / RS422 isolator / repeater / converter, which can be used to isolate one group of RS485 / RS422 equipment from another, or to extend the RS485 or RS422 distance to up to 4000 ft (1.2km); it can also can be used to convert a two-wire RS485 signal into a four-wire RS422 signal, and vice versa. This industrial opto-isolated RS485 / RS422 converter / repeater / isolator operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), features 600W surge protection, 15kV ESD static protection and 2500V opto-isolation circuitry, which effectively protects your RS485 / RS422 devices from ground loop, noise problems, transient surges, remote lightning and spikes.

The unit supports data rates up to 115.2K Baud, and features data format auto-sensing and self-adjusting, which automatically adjust baud rate, parity, stop bit and other COM port parameters to the devices that it is connected to. Therefore, it requires no DIP switch / jumper settings, software drivers or flow control, making the unit a highly reliable and truly plug-and-play device.

A separate external power supply is included in the package, and, thanks to the professional and unique casing design, the product can be mounted directly on a wall, panel or DIN Rail, without a need of using any unsecured DIN-Rail or wall-mount brackets.

Features

  • Isolates one group of RS485 / RS422 equipment from another
  • Converts 2-wire RS485 to 4-wire RS422 and vice versa
  • Extends RS485 or RS422's distance for 4,000 feet (1.2 km)
  • 2500V optical isolation, 300 to 115.2K Baud operation (auto-sensing & self-adjusting)
  • Built-in 600W surge protection, 15kV static protection and circuit protection
  • RS-485 / RS-422 auto-detection, no software drivers or manual setting required
  • Direct DIN-Rail (Rack) or Wall / Panel mounting (stackable)
  • Operating temperature: -40ºF to 185ºF (-40ºC to 85ºC)

WHY OPTICAL ISOLATION?

Ground Loops

lightning

Voltage Surges

Sparks

Ground Loops

Ground loop currents can flow through “the path of least resistance” via either the common earth ground or the ground wire and cause serious damages to the connected devices.

Optical isolation uses an LED (Light Emitting Device) and a photosensitive transistor to transfer data across the isolation barrier - typically an air gap; in other words, data is transmitted using light instead of electrical signals, so there is no physical connections between the grounds and the data lines, thus removing the ground loop problems.

Remote Lightning

Serial networks are often exposed to remote lightning because of the long distances and the surrounding electrical equipment.

Optical isolation uses an LED (Light Emitting Device) and a photosensitive transistor to transfer data across the isolation barrier - typically an air gap; in other words, data is transmitted using light instead of electrical signals, so there is no physical connections between the connected devices, thus effectively preventing remote lightning, voltage surges, and sparks from destroying other parts of the system.

Voltage Surges

Because of the long distances and the surrounding electrical devices, voltage surges can run across the system and cause damages to the valuable equipment.
