8.2.5 Analog Control / Output Devices
The CR1000 can scale measured or processed values and transfer these values in
digital form to an analog output device. The analog output device performs a
digital-to-analog conversion to output an analog voltage or current. The output
level is maintained until updated by the CR1000. Refer to the appendix
Continuous Analog Output (CAO) Modules (p. 563) for information concerning
available continuous analog output modules.
8.2.6 TIMs
Terminal Input Modules (TIMs) are devices that provide simple measurementsupport
circuits in a convenient package. TIMs include voltage dividers for
