2-2-3-1. Power consumption evaluations for parallel connection
Power consumed by a F159 can vary depending on the number of load cells
connected in parallel. For an each additional 350Ω load cell, power requirement
will increase by approx.0.13 A.
The system must be so designed that it can provide enough power to drive the
whole system including F159 and CJ series units (CPU and I/O units). Select a
power unit with ample capacity.
Depending on the specification of CJ series device used, up to ten units can be
connected to a F159.
(Some CPU units allow expanded installation up to 40 units)
