Terminal connection
Weighing module is a measurement module with high accuracy, which can be used for low level
signal down to 1.5μV reliably. To acquire operation with no fault, it’s essential to assemble and
wire cable correctly.
Following these rules to wire the weighing sensor:
1) If more than 1 sensor would be connected (in parallel), use a terminal box. If distance from the
senor to module is larger than to terminal box, a specified expansion box.
2) Cable Shield should always connect to the Cable gland of terminal box or expansion box.
3) Twisted Pair wire should be used and shielded:
Sensor wire SEN+/SEN-
Voltage measurement wire SIG+/SIG-
Power voltage wire EXC+/EXC-.
4) The shield must be connected to the shielded joint clamp.
1. 4-wire connection for the weighing sensor
When connecting 4-wire sensor, you must terminal the EXC+ with SENS+, EXC- with SENS-, or
else the module cannot work normally.
2. 6-wire connection for the weighing sensor
