Installation Guidelines
Ensure the ControlLogix chassis is powered down before inserting or removing the module to prevent electrical damage.
Verify the module is fully seated in the chassis slot and secured with the top and bottom latches.
Use appropriate shielded cabling for input signals to minimize electromagnetic interference (EMI).
Ensure proper grounding of the chassis and power supply common to maintain signal integrity.
Handle the module using ESD-safe practices to prevent damage to internal electronic components.
FAQ
What does 'individually isolated' mean for this module? Individually isolated means that each of the 16 input channels is electrically separated from the others, which helps prevent cross-talk and protects the system from ground potential differences between field devices.
Is the 36-pin terminal block included? Typically, the removable terminal block (RTB) is sold separately or included based on specific regional packaging; please verify your order contents if you require a new RTB.
