60 views

Published on

The 1756-WM is a weighing module designed to directly plug into the Allen-Bradley 1756 ControlLogix chassis.

Intended for inventory measurement and process control, the 1756-WM offers users simple configuration and is suitable for tank, silo, vessel and hopper weighing in the United States and Canadian markets.

The weighing module seamlessly integrates weighing into the Allen-Bradley PLC by directly fitting into a single slot in the 1756 ControlLogix chassis via a screw connection plug. The weighing module is powered from the input/output chassis backplane and needs only the load cells for connection.
