C.11 Option 27: 8-Channel High Drive 115
C.11.5 Connecting Load(s) to Output Bus
The following example illustrates use of different types of SEL relays connected to the output bus.
Total Load Current: 250 mA (peak) per driver or less.
Note 1:
Shielding is optional. However, if shielding is used, connect drain wire at source end of cable to a
local surge ground. Maintain shielding throughout bus by connecting drain wires together at each
junction or drop point. Do not connect drain wires at ends of cables. Do not connect drain wires
to signal wires. Do not connect shield to ground at more than one location, as this may result in
circulating currents.
