1.6 Power Wiring (continued)
1.6.5 Auxiliary Power, Single Supply
Figure T1.5 below shows how to wire main and auxiliary power to the SMD23E2 and SMD24E2 units when
using a single power supply. Colors in parentheses are the appropriate wire colors for the CNPL-2M and
CNPL-5M cables.

1.6.6 Auxiliary Power, Dual Supply
Figure T1.6 below shows how to wire main and auxiliary power to the SMD23E2 and SMD24E2 units when
using two power supplies. Note that the two supplies can supply different voltages. Colors in parentheses are
the appropriate wire colors for the CNPL-2M and CNPL-5M cables.

1.7 Input Wiring
Inputs 1 and 2 are single ended inputs that share the DC Common return pin. They accept 3.5 to 27 Vdc with-
out the need for an external current limiting resistor. The inputs can survive surge voltages to 35 Vdc. Figure
T1.7 below shows how to wire discrete DC sourcing and sinking sensors to inputs 1 and 2 of the SMD23E2
or SMD24E2. Colors in parentheses are the appropriate wire colors for the CNPL-2M and CNPL-5M cables.
