Chapter 2 Discrete and Analog Expansion I/O Features
The 2085-IA8, 2085-IM8, 2085-IQ16 and 2085-IQ32T modules update the
controller with new data whenever an input point transitions from On to Off and
Off to On.
On to Off and Off to On filter times can be adjusted through the Connected
Components Workbench software. These filters improve noise immunity within
a signal. A larger filter value affects the length of delay times for signals from these
modules.
You can select from a series of operational ranges for each channel. The range
designates the minimum and maximum signals that are detectable by the module.
Discrete Output
Output modules may be used to drive a variety of output devices. Typical output
devices compatible with the outputs include:
• motor starters
• solenoids
• indicators
Follow these guidelines when designing a system.
• Make sure that the outputs can supply the necessary surge and continuous
current for proper operation. (See Specifications on page 45 for more
information.)
• Make sure that the surge and continuous current are not exceeded. Damage
to the module could result. When sizing output loads, check the
documentation supplied with the output device for the surge and
continuous current needed to operate the device. The Micro800 standard
digital outputs are capable of directly driving the Micro800 standard
digital inputs.
Analog Expansion I/O
Features This section pertains to the following Micro800 analog expansion I/O modules:
TIP User-configurable options are not available in Connected Components
Workbench for discrete output modules.
IMPORTANT On controller minor and major fault, all output channels are de-energized.
