DRN4 - V2
Phone: [phone]
Website: workaci.com
GENERAL INFORMATION
The DRN4 is a resistive output motor actuator
interface that accepts several types of DDC system
signals. The DRN4 output is 0 to 135 ohms. The input
signal types are eld selectable by an 8-position DIP
switch. The oating point input accepts two digital
signals, one for increase and the other for decrease.
The oating point full scale rate of change is 55
seconds. Some triac input signals require an
accessory. The DRN4 is supplied in an enclosure that
can be directly mounted to a 1/2 inch knockout on
the motor actuator. Color coded wire leads with
spade connectors are provided for electrical
connections. Some triac inputs require a Triac
adapter kit. Johnson Control triac input signal
requires a 1,000 ohm 1/2 watt resistor and is included
with all DRN4s.
MOUNTING INSTRUCTIONS
Tools needed may include a Phillips screwdriver to
remove actuator cover screws, 3 wire nuts for two
signal and one common wire connections and a
voltmeter for troubleshooting if necessary. Turn o
power to the actuator and remove the actuator
cover. Remove a knock-out on the actuator near the
actuator control terminals. Open the access cover on
the DRN4 and set the switches to the desired mode
of operation. Replace the switch access cover on the
DRN4 and remove the outermost lock-nut from the
DRN4 box connector tting. Feed the DRN4 wires
through the actuator knock-out and the lock-nut.
Tighten the lock-nut onto the DRN4 tting. Connect
the DRN4 leads with spade connectors to the correct
actuator terminals, the external control source and
the power source. Wire nut any unused wire and
replace the actuator cover.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect
or disconnect wiring with power applied.
• When using a shielded cable, ground the
shield only at the controller end. Grounding
both ends can cause a ground loop.
• It is recommended you use an isolated

WIRING INSTRUCTIONS (Continued)
UL-listed class 2 transformer when powering the unit with 24VAC. Failure to wire the devices with
the correct polarity when sharing transformers may result in damage to any device powered by
the shared transformer.
• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or
other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI
Part: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DC
Transorb or diode, connects to the positive side of the power supply. Without these snubbers,
coils produce very large voltage spikes when de-energizing that can cause malfunction or
destruction of electronic circuits.
• All wiring must comply with all local and National Electric Codes.

CHECKOUT
After DIP switches for the signal input compatible with the external controller are set, power the actuator
and have the external controller send a minimum signal and then a maximum command signal to verify
proper actuator positioning. The LED under the cover will indicate according to the following:
MANUAL OPERATION WITH OVERRIDE BUTTON
Manual operation is allowed by placing dip switch (7) in the “OFF” position. Pressing override button
allows you to manually simulate the input range selected by the DIP switches (analog, pulse or tri-state).
(Note: Override button will NOT WORK in 1-5V, or 0-5V setting.)
ANALOG
Output ramps up while button is pressed (LED is o at 10VDC maximum signal), when released the output
will begin ramping down to zero (LED is on at 0VDC minimum signal). Between minimum and maximum,
the higher the input voltage, the shorter the LED pulse.
PULSE
Pressing override button simulates signal within the pulse range selected. LED ashes only when PWM
signal is being received.
FLOATING POINT
Output will ramp up while button is pressed (55 seconds for a full scale) and remain at point of release. LED
remains lit all the time. Remove power to DRN4 to reset to zero.
TRIAC INPUT
When using a triac input signal from an external controller, a Triac Adapter Kit must be ordered with the
DRN4. Connect the black common (-) wire from the power source, and the black common wire on the triac
adapter to the incoming power lead.
Suggestion: Clip o a short section of the power wire to include the female connector. Clip o the male
spade connector on the DRN4 black lead, then wire nut triac adaptor lead, DRN4 lead, and the power wire
with the female connector together. Plug into motor. Wire nut the triac adapter red wire and the DRN4
yellow wire together, the other triac adapter black wire and the DRN4 green wire together.
Johnson Control Triac input signals require only the installation of a 1K ohm ½ watt resistor. The resistor is
added across the DRN4 signal input wires (yellow and green), and wire nut to the external controller signal
leads. An added precaution would be to wrap resistor with electrical tape.
