3. Phone jack (Ø 3.5) for manual ON/OFF control
Lighting can be turned ON and OFF manually when the phone plug is inserted into the phone
jack. The LED lights will turn ON when the signal is connected to ground and will turn OFF
when the signal is disconnected from ground.
Phone plugs
Contact your nearest CCS representative if you need to extend the control signal cable or
operate in an extremely noisy environment. Cables should not be extended more than 3 m.
Potentially harmful noise may be eliminated by installing a 0.01 to 0.1µF capacitor between the
signal and ground to ensure proper operation of this product. Phone plugs are not included
with the power supply kit, but optional 3m cables with plugs are available.
Note: Please read instruction guide using optional cable.

The 24V output of the PLC cannot be input as it
is. (Maximum allowable input voltage: 5.5V)

Case
When using the PD2 in a noisy environment,
we recommend that you isolate the signal and
ground lines from the control unit with
photo-couplers or photo-MOS relays. Any
element that supplies around 10mA can be
used to drive the circuit.
