Precautions On Output Wiring - Panasonic FP7 Series User Manual

3.1 Wiring Precautions
r: Internal resistor of limit switch (kΩ)
R: Bleeder resistor (kΩ)
The input off voltage is 2.5 V. Therefore, when the power supply voltage is 2.4 V,
the input impedance is 3.6kΩ.

3.1.3 Precautions on Output Wiring

■
Connection of inductive loads
When connecting an inductive load, a protective circuit should be installed in parallel with the
load.
When connecting the DC type inductive loads and relay type output unit, be sure to connect a
diode for protective circuit across the ends of the load. This will affect the life of the relay.
When using an AC inductive load (Relay output type)
■
Connection of capacitive loads
When connecting the loads with large in-rush currents, be sure to connect a protection circuit in
series with the load.
