4.3.5.5 Connecting between 2 and 8 load cells (650 Ω) using a 6-wire
connection cable
Connections are made via cable junction box PR 6130/.. using connection
cable PR 6135/.. or PR 6136/... .
Recommendation
–
Install cable in steel pipe connected to a ground potential.
–
The distance between the measuring cables and the power cables should
be at least 1 m.
Load cell supply circuit
–
Load resistance of load cell circuit ≥75 Ω, e.g., 8 load cells of 650 Ω each
–
The supply voltage is fixed at U
DC
= 5 V and protected against short cir
cuits.
