Fiber optic converter for RS-485 2-wire bus systems

Data sheet

Description

PSI-MOS-RS485W2/FO…

fiber optic

T-couplers

convert

to two fiber optic cables.

Virtually any cascadable star and tree structures can be

created using integrated bit retiming, even in a redundant

version if required. In this case, the required devices are

snapped onto DIN rail connectors, which ensure that the

supply voltage and data signals are routed through.

Devices with different transmission technologies (polymer,

HCS, and glass fiber) can be freely combined within a star

coupler.

PSI-MOS-RS485W2/FO 660...

devices are networked

using polymer fiber cable for distances up to 100 m and

HCS fiber cable for up to 800 m. They are connected via

F-SMA quick mounting connectors, which can be

assembled locally within a few minutes.

PSI-MOS-RS485W2/FO 850 ...

devices are available for

longer paths and can be used for distances up to 2800 m

using HCS fiber cable and B-FOC (ST

) fast connection

technology and up to 4200 m using multi-mode glass fiber

cable.

The PSI-MOS system can be used with input voltages from

18 V DC to 32 V DC and in a temperature range from -20°C

to +60°C.

PSI-MOS-RS485W2/FO…

devices can be used to convert

RS-485 2-wire bus systems to fiber optics.

All bus systems with 10/11-bit UART data format and NRZ

data encoding are supported. This includes popular bus

systems such as:

– Modbus ASCII/Modbus RTU

– SUCONET K

– S-BUS

– DH-485

– Various other company-specific bus systems

A transparent protocol is used to convert all common

transmission speeds up to a maximum of 500 kbps. The

integrated optical diagnostics enable fiber optic paths to be

monitored continuously during installation and even during

operation. The floating switch contact is activated when the

signal output on the fiber optic paths drops to a critical level.

This early alarm generation enables critical system states to

be diagnosed before they result in failure.

PSI-MOS-RS485W2/FO…

E termination devices

convert

an RS-485 interface to a fiber optic cable. They are ideal for

point-to-point connections.
