Data transmission
see chapter 3.1.2 "Protocol-specific characteristics of the
DDLS 548i"
Tab. 12.2:
Electrical equipment
Switching input
• +18 … +30 V DC depending on supply voltage
Transmitter not active - no data transmission
• 0 … 2 V DC
Transmitter active - normal function
Switching output
• +18 … +30 V DC: received signal level/SIGNAL QUALITY
ok (normal operating range)
• 0 … 2 V DC: intensity warning SIGNAL QUALITY
• Output current I max. = 60 mA.
Operating voltage U
B
+18 … +30 V DC
For UL applications: only for use in "class 2" circuits in accor-
dance with NEC.
Current consumption
Approx. 200 mA at 24 V DC (no load at switching output)
Data transmission delay time
• Protocol propagation times:
Constant delay time per path (2 devices): 12 µs
• Distance-dependent delay:
Distance 0 m: 0.00 µs
Distance 200 m: 0.66 µs
