Selecting Contact Protection
Inductive load devices such as motor starters and solenoids may
require the use of some type of
surge suppression to protect the
controller output contacts. Switching inductive loads without surge
suppression can significantly reduce the lifetime of relay contacts.
Suitable surge suppression methods for inductive ac load devices
include a varistor, an RC network, or an Allen-Bradley surge
suppressor.
These components must be appropriately rated to
suppress the switching transient characteristic of the particular
inductive device.
For inductive dc load devices, a diode is suitable. A diode, catalog
number 1N4004, is acceptable for most applications.
A surge suppressor can also be used. See the table on page 49.
Locate the suppression device as close as possible to the load device.
Transistor Output Transient Pulses
This section applies to the following SLC 500 fixed I/O processors and
SLC 500 I/O modules that have transistor outputs.
