The
PSI-REP-RS485W2
DIN-rail mountable, modular
RS-485 repeater is designed to meet the high requirements
associated with the use of fieldbus systems. The device is
snapped onto standard EN DIN rails in the control cabinet
and supplied with 24 V DC. The main areas of application
are:
– Electrical isolation/bus segmentation
– Increasing system availability
– Increasing the range
– Increasing transmission speeds
– Extending the number of devices to n x 32
– Implementing hybrid/network structures
– Modular star couplers
The repeater can be used universally in all common
2-conductor bus systems (RS-485W2).
The following features of the repeater are particularly
outstanding:
– Supports all bus systems with UART/NRZ data format
and 10/11-bit character length
– Transmission speed of 4.8 kbps to 500 kbps
– Automatic transmit/receive changeover
– Integrated, connectable termination resistors
1.1
RS-485 signals with a bit distortion of up to 35% can be
reliably detected using the bit retiming function and are
converted to their original bit form before being transferred
to the next segment. This data processing function means
that a virtually unlimited number of repeaters can be aligned
without an impermissible level of bit distortion.
1.2
Bit oversampling
The bit oversampling function can be used to detect and
filter malfunctions so that they are not transferred to the next
segment.
