Other control cable types
There are two types of data cable commonly used to connect to electronic lamp drivers (ballasts).
1-10V cabling
1-10V uses mains rated polarized cabling; typically, a single pair "figure-8" cable. Positive wire may have a dashed
line.
DDBC, DBC, DMB, DDMC, DMC controllers and DGBM, DMD modules provide 1-10 V control and automatically
sink or source current depending on the connected driver. The DDBC1200 controller can provide 0-10 V or 1-10 V
dimming in sinking and sourcing mode.
Typical considerations when installing a 1-10 V circuit:
•
Loads must not use a mixture of sinking and sourcing drivers.
•
An analogue circuit can typically accommodate around 10 luminaires per controller. The maximum
number of drivers allowed on an analogue output depends on controller specifications such as, box
loading, channel loading and circuit characteristics. Check the controller/module specification sheet for
detailed information.
•
0/1-10 V control signal is polarity sensitive. Positive and negative outputs from the controller must be
connected to the corresponding positive and negative inputs on the driver. The circuit will not work if
wires are reversed.
•
If the control signal is not connected or a wire is broken, the driver shall go to the maximum value or the
system failure level, if applicable, to keep the lights on.
•
If 0/1-10 V wiring is run in parallel with AC wiring, for improved noise immunity, it is recommended to use
shielded cabling with the shield grounded to Earth at the controller. Unshielded analog control wiring can
act as antennae, which may be interpreted by the driver as changes in the control voltage resulting in a
flicker effect.
•
As 0/1-10 V is an analogue protocol, the signal can suffer from voltage drop over a long cable run >30 m
(100 feet), directly impacting the light intensity. Therefore, stranded wire should be used with a cross
sectional area of at least 0.82 mm

(18 AWG) and the cable run should be less than [90 m] (300 feet).
