NOTE:
1. Use only shielded cables for control cables.
2. Route control cables in separate cable trunks at
least 7-3/4 inches (20 cm) away from motor and
power cables.
After completing analog input DIP switch settings and wiring for control
terminal connections, reattach the SED2 cover and operator panel.

Figure 29. SED2 Control Terminals on I/O Module.
NOTES: 1. Analog inputs 1 and 2 can be optionally configured for direct
connection of a Ni 1000 temperature sensor. The sensor
connects between terminals 4 and 2 or 11 and 2.
2. 0 to 10 Vdc analog inputs connect between terminals 2 and 3.
3. 0 mA to 20 mA and 4 mA to 20 mA analog inputs connect
between terminals 3 and 4.
When using a 4 mA to 20 mA input, DIP switches must be
set to appropriate input.
