shield sensor scale

Scope

Provide support for remote machine control, using standard interfaces, i.e. Modbus RTU & 4-20mA. Typical applications include the control of machines “brain”, namely PLCs, and energy consumpetion, using non-obstructive current sensors.

This shield is still under development. Registrer your interest to discuss further options.
