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.
