The M1433B 6RTD module provides 6 resistance
temperature detector 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.
The module will convert the RTD resistance reading
directly into degrees C or F to a resolution of 0.1
degrees.
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.
In addition, Rate of Change (ROC) alarms per input are
supported.
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.
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.
