Option I – Integrated controller with industrial and RC servo
interfaces
1 - Green – Current input signal (4–20 mA interface mode)
2 - Blue – Voltage input signal (0–5V interface mode)
3 - Purple – Position Feedback signal (Proportional 0–3.3 V)
4 - White – RC input signal (RC-servo compatible mode)
5 - Red – Power (6V model or 12V model)
6 - Black – Ground
The –I actuator models feature an on-board software-based
digital position controller. The controller is not user-
programmable. The six lead wires are split into two con-
nectors. Leads 4, 5 and 6 terminate at a universal RC servo
three-pin connector (Hi-Tec™ and Futaba™ compatible). Leads
1, 2, and 3 terminate at a separate, similarly sized connector.
When the actuator is powered up, it will repeatedly scan leads
1, 2, 4 for an input signal that is valid under any of the four
supported interface modes. When a valid signal is detected,
the actuator will self-configure to the corresponding interface
mode, and all other interface modes and input leads are
disabled until the actuator is next powered on.
0–5 V Interface Mode: This mode allows the actuator to be
controlled with just a battery, and a potentiometer to signal
the desired position to the actuator – a simple interface for
prototypes or home automation projects. The desired
actuator position (set point) is input to the actuator on lead 2
as a voltage between ground and 5 V. The set point voltage
must be held on lead 2 even when the desired actuator stroke
position is reached. Lead 2 is a high impedance input.
4–20 mA Interface Mode: This mode is compatible with PLC
devices typically used in industrial control applications. The
desired actuator position (set point) is input to the actuator on
lead 1 as a current between 4 mA and 20 mA. The set point
current must be held on lead 1 even when the desired
actuator stroke position is reached.
RC Servo Interface Mode: This is a standard hobby-type
remote-control digital servo interface (CMOS logic),
compatible with servos and receivers from manufacturers like
Futaba™ and Hi-Tec™. The desired actuator position is input
to the actuator on lead 4 as a positive 5 Volt pulse width
signal. A 1.0 ms pulse commands the controller to fully retract
the actuator, and a 2.0 ms pulse signals full extension. If the
motion of the actuator, or of other servos in your system,
seems erratic, place a 1–4Ω resistor in series with the
actuator’s red V+ lead wire.
PWM Mode: This mode allows control of the actuator using a
single digital output pin from an external microcontroller. The
desired actuator position is encoded as the duty cycle of a 5
Volt 1 kHz square wave on actuator lead 2, where the % duty
cycle sets the actuator position to the same % of full stroke
extension. The waveform must be 0V to +5V in order to
access the full stroke range of the actuator.
Option R – RC Linear Servo
WIRING: (see last page for pin numbering)
1 - White – RC input signal (RC-servo compatible)
2 - Red – Power (+6 VDC)
3 - Black – Ground
Note: Reversing the polarity of pins 2 and 3 may permanently
damage the actuator
The –R actuators or ‘linear servos’ are a direct replacement for
regular radio controlled hobby servos. The desired actuator
position is input to the actuator on lead 1 as a positive 5 Volt
pulse width signal. A 1.0 ms pulse commands the controller
to fully retract the actuator, and a 2.0 ms pulse signals it to
fully extend. If the motion of the actuator, or of other servos
in your system, seems erratic, place a 1–4Ω resistor in series
with the actuator’s red V+ lead wire.
The –R actuators are available in 6 volt and 30, 50 and 100 mm
strokes only.
This is a lower cost option for the RC hobby market. While the
supported control options are reduced, the –R retains the same
great precision and cycle life as the –I.
