High-Speed, Isolated, RS-422/485 Repeater
485OPDR-HS
485OPDR-HS
The 485OPDR-HS is a high speed, optically isolated RS-422/485 repeater
that supports data rates up to 1.5 Mbps, making it suitable for use in
fieldbus systems such as Profibus.
Isolation
The 485OPDR-HS provides 2 kV digital Isolation with 8 kV air ESD
protection and 600 W transient voltage suppression on the data lines.
Range Extension
The 485OPDR-HS can be used to extend the range of a network up to 4000
ft. (1.2 km), depending on data rates, and to add additional nodes. 2-Wire
RS-485, 4-Wire RS-485 and RS-422 are supported. Data signals and the
power inputs connect to built-in terminal blocks.
Enclosure
The repeater operates on externally sourced 10 to 30 VDC power. The
enclosure has a DIN rail mount that is designed to fit easily on a standard
35mm rail.

Profibus Overview
PROFIbuS “Process Field Bus” is communication standard for
automation technologies and applications.
PROFIbuS DP (“Decentralized Peripherals”) is the most common
version of Profibus. It is used for deterministic communication
between Profibus masters and their remote I/O slaves and supports
numerous standard diagnostic options. Applications include production
automation processes and operating sensors/actuators via
centralized controllers.
PROFIbuS PA (“Process Automation”) is less prevalent and tends
to be application specific. It is often used to monitor measurement
equipment via process control systems. PA and DP can be used
together to help bridge application networks. PA uses the same
protocol as DP so it can be linked to a faster DP backbone network to
better transmit process signals from equipment to controllers. PA can
also be used in hazardous areas. The IEC 61158-2 rated physical layer
can bus-power instruments and limit current flow to prevent
explosive conditions.
PROFIbuS FMS (“Field Bus Message Specification”) is a complex
communication protocol for more sophisticated communication needs.
It supports non-deterministic data communication between
Profibus masters.
