INTERBUS 500kBit/s / RS 422
Leuze electronic DDLS 200 25
TNT 35/7-24V
6 INTERBUS 500kBit/s / RS 422
The INTERBUS model of the DDLS 200 has the following features:
• Operating ranges 30m, 120m, 200m, 300m, for INTERBUS
• Electrically isolated interface
• The DDLS 200 is not an INTERBUS participant
• Protocol-independent data transmission, transparent compared to other RS 422 protocols
• 500kBit/s fixed transmission rate with INTERBUS,
with RS 422 generally lower transmission rates as well
• Operating range 500m for RS 422 up to 100kBit/s
• Cascading of several DDLS 200 is possible (see Chapter 4.3)
6.1 Electrical connection INTERBUS 500kBit/s
The electrical connection to the INTERBUS is made at terminals DO… / DI… and COM as shown in
Figure 6.1.

ATTENTION!
Please be sure to observe the installation requirements (bus cables, cable lengths,
shielding, etc.) defined in the INTERBUS standard EN 50254
