Delta Controls
Input and Output Wiring
Inputs and outputs on the DAC-606 controller follow the same general wiring requirements as other Delta
Controls products. Recommended cable types should be used as listed below. Refer to the Delta Controls
Wiring Guidelines for more details.
Recommended Cable Type
2 Conductor, 18 AWG, Unshielded
2 Conductor, 22 AWG, Shielded
Input Configuration
The input must be configured to accept the signal used by
the input device. Place the jumper for each input in the
correct location on the Input Type Selector Block. The
diagram to the right shows the factory default selection of
10 KΩ.
4-20mA
For sensors that use a 4 to 20 mA signal.
10K
For 10 KΩ Thermistor temperature
sensors, as well as Dry Contact binary
inputs.
5V
For sensors that use a 0 - 5 VDC signal.
10V
For sensors that use a 0 -10 VDC signal.
Binary Output Power Source
The binary triac outputs can be selected to use either an
internal or external power source by placing the two
jumpers in the correct locations. The diagram to the left
shows the factory default selection of External Power
Source.
Internal - 24 VAC Power is provided internally from within
the board right to the output terminals. No external
transformer is required. The associated triac outputs are
"hot" contacts. Note that the power supply should be sized
appropriately to handle the additional loading.
External - Power needs to be provided externally to the
board from a nearby transformer appropriately connected
to the output wiring. The associated triac outputs are not
"hot" contacts, except by means of the external
transformer.
NOTE - Triacs are solid-state components that are only
appropriate for switching 24 VAC. They cannot be used to
switch 24 VDC. They also have a small leakage current
and are not appropriate for "dry contact" applications.
