F158

Loadcell Interface For OMRON SYSMAC α

Product outline

Since inter-equipment wiring is not required, weighing system construction time can be reduced with serviceability improved.

F158 is a weighing controller that allows direct connection to the base module of OMRON’s general-purpose sequencer SYSMAC α. Since inter-equipment wiring is not required, weighing system construction time can be reduced with serviceability improved. With the power supply shared, drastic cost reductions can be achieved.
