Installation Guidelines
Ensure the ControlLogix chassis power is removed before inserting or removing the module to prevent electrical damage.
Verify that the module is fully seated in the chassis slot and that the locking tabs are engaged.
Handle fiber-optic connections with care; ensure connectors are clean and free of debris to maintain optimal signal integrity.
Route fiber-optic cables away from high-voltage power lines to prevent potential interference and physical damage.
Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect internal circuitry.
FAQ
What is the primary function of the 1756-DMA31? This module acts as a bridge, allowing the ControlLogix controller to communicate with drives over a SynchLink connection, enabling synchronized motion control across a production line.
Does this module require external power? The module draws its required power directly from the ControlLogix backplane. It consumes 1.35 A at 5 VDC.
