Chapter 3 System Overview
Control Output
For control applications, the actuator has the following advantages:
• Higher voltage and power rating than the digital output channels.
The actuator switches can also be used to control power devices.
• When used with high-power devices, however, it is critical that you
provide protection to the switch from capacitive and inductive loads
to ensure maximum relay life (for more information on attenuators,
see the discussion on page 309).
