Module Features
Input Compatibility
ControlLogix high-speed analog I/O module inputs convert the following
analog signals into digital values:
• Vo l ts
• Milliamps
The digital value that represents the magnitude of the analog signal is then
transmitted on the backplane to an owner-controller or other control entities.
Output Compatibility
ControlLogix high-speed analog I/O module outputs convert a digital value
delivered to the module via the backplane into an analog signal:
• -10.5…10.5V
or
• 0…21 mA
The digital value represents the magnitude of the desired analog signal. The
module converts the digital value into an analog signal and provides this signal on
the module's screw terminals.
