ARM100
Digital Input/Output Module
Operational LEDs

Three large LEDs on top of the ARM100 indicate the module’s operating condition. A
red ‘Power’ LED, a yellow ‘Running’ LED
and a green ‘Data OK’ LED are clearly visible to confirm correct operation.

Built-in I/O diagnostics

The status of the inputs and outputs is
easily visible on the top of the module. A
separate red LED is provided for each input
and output. When the ARM100 turns an
output ‘on’, the LED confirms the action. All
LEDs work independently to display the
condition of each input and output,
providing constant feedback of the I/O
system.

Flexible power options

The ARM100 module was designed to operate from a wide range of DC voltages.
Whether you provide only 10 volts or as
much as 32 volts, the ARM100 will operate
properly. The module can be connected to
an existing power supply or, if your system
does not have DC power available, a separate, DIN rail-mounted supply is available
from METTLER TOLEDO.

DIN rail-mounted

Typically, the ARM100 is mounted in a
small equipment enclosure or a large control cabinet with other control devices. The
ARM100’s rugged DIN rail mounting makes
installation simple and fast. If your application requires that the ARM100 and its
power supply be located in a harsh or hazardous environment, optional stainless
steel or explosion-proof/flameproof enclosures are available.

ARM 100 Digital I/O
Expand scale terminal functionality
The ARM100 digital I/O module extends the discrete
input and output control of METTLER TOLEDO industrial terminals to remote locations. When the number
of internal I/O connections available in a terminal is
insufficient or if the actul control devices are located a
long distance from the terminal, the ARM100 provides a
solution. Multiple ARM100s can be connected in a network to increase the total number of inputs and outputs
available for installations. The ARM100 is designed for
simple DIN rail installation in cabinets or enclosures.
An optional stainless steel enclosure permits its use in
harsh environments, where protection from contaminants and vigorous washdown are necessary. The
ARM100 can also be installed inside an explosion-proof
or flameproof enclosure for applications within hazardous (explosive) areas.
