Controls using DC Analog Input/
Outputs
(Standard Low Voltage
Multiconductor Wire)

Before installing any connecting wiring
between the unit and components utiliz-
ing a DC analog input\output signal, refer
to Figure 2 for the electrical access loca-
tions provided on the unit.

a. Table 3 lists the conductor sizing

guidelines that must be followed when
interconnecting the DC binary output
devices and the system components
utilizing a DC analog input\output sig-
nal to the unit.

Note:
 Resistance in excess of 2.5 ohms per
conductor can cause deviations in the
accuracy of the controls.

b. Ensure that the wiring between con-

trols and the unit’s termination point
does not exceed two and a half (2.5)
ohms/conductor for the length of the
run.

c. Do not run the electrical wires transport-

ing DC signals in or around conduit
housing high voltage wires.

d. Route low voltage wiring per illustra-
tions on page 22.
