require no further adjustment by the customer.
The board is available in aluminum case for DIN rail mounting.

The DLC
module is a load cells signal amplifier. The supply voltage of the
transducer is 5 Vdc with the possibility of 4 or 6 wire connection. With six-wire
connection, you make a correct voltage drop compensation on the connecting
cables, for greater accuracy.
The fieldbus and power supply of the load cell are galvanically isolated via DC /
DC converter, among the 24 Vdc power supply. This allows the connection of
several weighing systems to a data collection system (PLC or PC) with the use of
the same power supply (+24 Vdc) common to other devices without any kind of
problem.
