Data Highway + (DH+) / Remote I/O (RIO)
32 DDLS 200 Leuze electronic
8 Data Highway + (DH+) / Remote I/O (RIO)
The DH+/RIO model of the DDLS 200 has the following features:
• Operating ranges 120m, 200m, 300m
• Electrically isolated interface
• Direct connection to the Data Highway + and Remote I/O bus from Rockwell Automation
(Allen Bradley)
• Adjustable transmission rate 57.6 / 115.2 or 230.4kBit/s
• Cascading of several DDLS 200 is possible (see Chapter 4.3)
8.1 Electrical connection DH+ / RIO
The electrical connection to the DH+ / RIO bus is made in accordance with the table on the connection
board at the terminals 1, 2 and 3. These terminals are each provided twice for wiring through the bus.
Cable to be used: Bluehouse Twinax (Belden 9463 or Allen Bradley 1770-CD)
Figure 8.1: Connection board of the DH+ / RIO model
ATTENTION!
The right DH+ / RIO connections 1 and 3 are equipped standard with an 82 W resistor for
terminating the bus. Remove this terminating resistor when the bus cable in the DDLS 200
is to be wired through to another network device, i.e. the DDLS 200 is not the last device
on the bus cable. The use of the DDLS 200 is limited to bus systems with 82 W termination.
