DESCRIPTION
The M1434D 8AI ISO module provides 8 inputs that
can be individually configured for millivolts/Volts or
Current inputs. The inputs are individually isolated. This
intelligent module is software configurable, and allows
each input to be configured for a different input type
and range. The input value can scaled in the module
into Engineering Units of the user’s choice
Current inputs are measured using an internal 220 Ohm
resistor switched in across the input terminals.
Each input has four software settable alarm/trip
setpoints and a deadband value. The status of the
alarm/trip signals is available as derived digital inputs
from the module.

The module may be inserted into any I/O slot in a
Maxiflex system.
Inputs are terminated on plug-in screw terminals.
The module can be inserted or removed while the
system is powered.
Auto-detection capability allows the CPU to recognise
the presence of this module in the system.
All configuration and dynamic data are made available
to the system CPU through the module registers. The
module is configured by writing the appropriate values
to these registers, and the dynamic values are read by
reading from these registers.
