Weighing Module
Cabling Recommendations Introduction To help protect the signal from external noises induced in serial mode and from noises in common mode, follow these instructions. Kind of Conductors Use shielded twisted pairs of a minimum section of 0.28 mm2 (AWG24 gage). Cable Shielding Connect the measurement cable shielding to the ground on the module side only. You can also connect both ends of the shield to the ground if the grounds on either side of the connection are of good quality. On the Sub-D connectors, connect the cable shield to the cover of the connector, the PLC ground being connected by the tightening screws of the Sub-D connector. For this reason, the male SubD connector is screwed onto its female connection base. Cable Routing Keep the measurement wires as far as possible from the discrete input/output cables (particularly relay outputs) and the cables which transmit "power" signals. Instead of parallel routing (maintain a distance of at least 20 cm between the cables), cross them at right angles. NOTE: The measurement input is grounded via the module.
