(A) CO-M cable
A two-meter cable is provided in each unit without interface option. If you need a longer cable, please consult with our sales staff.

Master/slave

...up to 16 units

When noisy environment is presumed, the following -LGob option (optical interface) is required.

-LGob

Optical Interface Board ^{*1 *2}
With optical communication, isolation control is performed. As complete isolation is performed by means of optical fiber, this enables advance prevention of erroneous operation involved with transient phenomenon caused by surges, inductive lightning, external noise, etc.

• -LGob: Optical interface board + optical cable 2 meters
• -LGob(Fc5): Optical interface board + optical cable 5 meters
• -LGob(Fc10): Optical interface board + optical cable 10 meters
• -LGob(Fc20): Optical interface board + optical cable 20 meters
• -LGob(Fc40): Optical interface board + optical cable 40 meters

Select the optional optical interface board (-LGob) when using this DC power supply under the following conditions.

• Noisy environment including factories (Example: Motors or coils are used near power supplies and loads).
• Using with high voltage floating (more than 250 V).
• Installation distance of 2 meters or more between the DC power supply and a controller such as a computer, laptop, or Programmable Logic Controller (PLC).

Adapters (sold separately)
