Data Highway + (Dh+) / Remote I/O (Rio); Electrical Connection Dh+ / Rio - Leuze electronic DDLS 200 Technical Description

Data Highway + (DH+) / Remote I/O (RIO)

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)

Electrical connection DH+ / RIO

The electrical connection to the DH+ / RIO bus is made acc. to the table on the connection board at
terminals 1, 2 and 3. Each of these terminals is provided twice for wiring through the bus.
Cable to be used: Bluehouse Twinax (Belden 9463 or Allen Bradley 1770-CD)

Attention!
The right DH+ / RIO connections 1 and 3 are equipped standard with an 82 Ω resistor for
terminating the bus. Remove this terminating resistor when the bus cable in the DDLS 200
is to be wired through to another bus subscriber, 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 Ω termination.
