Installation Guidelines
Ensure proper grounding of the 1756 ControlLogix chassis backplane prior to controller insertion.
Handle the module using proper ESD protection to prevent damage to internal solid-state components.
Insert the controller firmly into any open chassis slot until the module locking tabs engage securely.
Install the 1756-BA2 lithium battery module before applying system power to ensure memory retention.
Maintain adequate clearance above and below the chassis for natural convection cooling and airflow.
FAQ
What memory configuration does the controller feature?
The module features 8 MB of standard application memory and 4 MB of dedicated safety memory.
What battery replacement model is required for memory retention?
The device requires a 1756-BA2 replacement battery.
Does the unit feature an embedded Ethernet port?
No, the device does not have an embedded network port; local serial connection is provided via an RS-232 port.
