Control Signal and Feedback
Locate the correct connection terminals/wires as shown on the previous page, then connect your input signal
on positions 1 and 2 (yellow and blue wires) as shown below. Feedback, if applicable, is connected to
position 4 (grey wire).

NOTE 1:
Usually, the actuators are
shipped for 4-20 mA signal input.
For 1-5 V signal input, remove 250
ohm resistor R66.
The actuator 4-20 mA output is internally supplying the signal current and can drive sufficient voltage for any
sensing resistor of up to 250 ohms.
The potential of the external GND after the sensing resistor may not be more than +6 VDC / -2 VDC away from
the power GND of the actuator.
This feedback signal output is only available in HANBAY RCx-AC-xxxAF model actuators.

NOTE 2:
Signal Gnd. is NOT
ISOLATED from Power Gnd. in all
RCx-AC-xxxAB basic models.
If your signal Gnd. is different from
Power Gnd. use HANBAY RCx-AC-
xxxAI or RCx-AC-xxxAF model
actuators.
NOTE 3:
DO NOT CONNECT pin 4
directly or through a multimeter only
to ground.
A sensing resistor of 50 ohms or more
needs to be present.
Not observing this warning will
damage the equipment.
