The M1432A 8TC module provides 8 thermocouple or
millivolt inputs. The inputs are individually galvanically
isolated. This intelligent module is software configurable,
and allows each input to be configured for a different
input type and range.
For temperature applications, the module will convert the
thermocouple reading directly into degrees C or F to a
resolution
of
0.1
degrees.
Thermocouple
upscale/downscale burnout can be selected by setting a
configuration bit in the module.
For millivolt inputs, the millivolt value can be read as
either a scaled percentage value or the actual mV value
as a signed integer to 2 decimal places. Ie 0.00% to
100.00% or –10.00 to +80.00mV. Over-range and
under-range inputs are read as –32768 and 32767
respectively.
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.
High inter-channel galvanic isolation allows inputs to be
connected to high common mode voltage sources
without detrimental effect.
With the aid of an accurate DC millivolt source and the
M1432A calibration software, the module can be field
calibrated by the user if required. (Calibration of the
internal thermocouple Cold Junction Compensation
requires the removal of the LED cover, but is not
normally required after factory calibration.)
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.
