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.

PCB电路板散热
电子设备工作会产生的热量,使设备内部温度迅速上升,若不及时将热量散发,设备会持续升温,器件就会因过热效,电子设备的可靠性将下降。所以,对电路进行散热处理十分重要。一、印制电路板温 ......
