The SW485 enables up to nine RS485 networks to be connected in a star topology. All the lines are equal. When data is received by any line, they are sent to all the other lines. Ideal for connection of a number of devices communicating via RS485, interconnection of several RS485 networks or signal edge enhancement for larger distances.

Special Offer: Discounts of 7%, 10%, 12.5% and 15% are available when you order 10, 25, 50 and 100 items or more of this product.

Enables up to 9 RS485 networks to be connected in a star topology.
Microporcessor processing of all signals.
Signal transmission with minimum delay - only 130 ns.
Maximum communication speed of RS485 lines: 1.5 Mbps
Possibility to configure the switching delay for automatic change of data flow direction (7 µs to 1.9 ms in several increments)
User-configurable connection of terminating resistors and bias resistors defining the idle state of the line. These resistors may be connected separately for each individual line.
Supplied with DIN Rail mount
Supply voltage 7 to 30 V DC.
All signals connected via a screw terminal.

Data from individual lines are only processed by logical circuits. Data received by any of the lines are sent to all the other lines. Individual lines have no buffer for data receipt.

When data arrive almost simultaneously to two lines, the system receives the data whose beginning was first registered. The other lines switch to “Transmission” and start to transmit the data. After the data receipt has been completed the system waits for a configured period of time (a so called “Switching Delay”). After this period has elapsed, all the lines switch to “Receipt” and wait for data to come.
