• When the length of the wiring is less than 5 m (approximate)
Remove the shorting bar 1 or the shorting bar 2 and connect the terminal (#1/#2 or #3/#4) to the contact.
- An external power supply is not necessary.
- A maximum of 2 sets of contacts can be connected (when both the shorting bar 1 and the shorting bar 2 are
removed.)
- The minimum rating for the contact is as below.
Voltage
5V or less
• When the length of the wiring is at least 5 m (approximate)
Remove the shorting bar 1 and the shorting bar 2 and connect an external power supply and the contact to the ter-
minals (#2 and #3) in series (do not use #1 and #4.)
- Connect #2 to the positive side of an external power supply, and connect #3 to the negative side of the external
power supply.
- The voltage for the connecting external power supply should be within a range of 5V minimum to 16V maximum.
The minimum rating for the contact depends on the voltage of the external power supply.
