Connection Principles
ModWeigh instruments can be configured in many different ways to suit any given application.
The display is normally located to suit an operator. The transmitter can be located in the field to reduce
field wiring or can be located with the display for a more conventional approach.
The I/O can conveniently be situated on a DIN rail in a cabinet.
