4.2.9 Wiring for Noise Control
When the LIO-06 Module is mounted and used in an environment where there is high-frequency noise from an external
device, the counter may not correctly execute counting. In this case, install a noise filter or a ferrite core to suppress the
high-frequency noise.
The following figure shows an example of installing a noise filter and ferrite cores.
„ Recommended Parts
ΠA fuse is inserted in the output common line of the LIO-06 Module for circuit protection. However, the fuse
may not be blown out in the cases such as layer shorts in outputs. To ensecure the circuit protection, pro-
vide a protective element such as fuse in each output as shown in the above diagram.
Π5 V, 12 V, and 24 V are available for phase-Z input voltage.
Note that the pin that is used will differ, depending on the input voltage.
Using the wrong pin may cause an accident.
At 5 V input: Use No.9 pin.
At 12 V input: Use No.34 pin.
At 24 V input: Use No.10 pin.
ΠIf you connect an inductive load, connect a diode parallel to the load to
absorb counter electromotive force.
ΠBackward voltage: 10 times the load voltage or greater
ΠForward current: Load current or greater
