Wiring Methods
Reducing Electrical Noise
Use the following formula to determine the resistance and rating for the
bleeder resistor.
When connecting a transistor or triac output to an output device having a high
surge current (such as an incandescent lamp), steps must be taken to avoid
damage to the transistor or triac. Use either of the following methods to
reduce the surge current.
Method 1
Add a resistor that draws about 1/3 of the current consumed by the bulb.
Method 2
Add a control resistor as shown in the following diagram.
Whenever possible, place I/O signal lines and power lines in separate ducts or
raceways both inside and outside of the control panel.
If the I/O wiring and power wiring must be routed in the same duct, use
shielded cable and connect the shield to the GR terminal to reduce noise.
When an inductive load is connected to an I/O Unit, connect a surge suppres-
sor or diode in parallel with the load as shown below.
