Discrete I/O; Serial Ports - Mettler Toledo IND780 Guide D'installation

• Programmable Logic Control (PLC) interfaces, including:
• Axle-780 (application software)
• Drive-780 (application software)
• COM-780 (communications module)
• Task Expert™
• InSite Configuration Tool
• Various brackets for wall and column mounting of the harsh enclosure
The scale measurement channel, serial and discrete I/O options are connected to the IND780
through six internal option slots. Various combinations of options may be ordered to match the
application solution requirements.

Discrete I/O

The discrete I/O interface options include both internal and remote I/O.
• The internal version is available with dry-contact relay or solid state relay outputs. Both types
• The remote I/O is supported with the ARM100 remote module that provides dry-contact outputs.
• A total of two internal Discrete I/O boards (8 inputs and 8 outputs) are supported and an

Serial Ports

Additional communications cards provide RS-232, RS-422 or RS-485 communication at rates
from 300 to 115.2k baud. A maximum of two serial communications cards may be installed in the
IND780.

will switch up to 30 volts DC or AC and up to 1 amp of current. The inputs are switch-selectable
as either active (for simple pushbutton control) or passive (for connection to PLCs or other
devices that supply their own power for the I/O). Each internal board supports four inputs and
four outputs.
The inputs are passive on the ARM100. Each ARM100 supports four inputs and six outputs. An
external 24-volt DC supply is required to operate the ARM100.
