MAXIFLEX 8TC/mV Module Model M1432 Individually Isolated 8 way Thermocouple Input Module. DATASHEET FEATURES • Fits in any MAXIFLEX base I/O slot 8 individually Isolated Thermocouple/millivolt Inputs High isolation voltage rating for industrial applications Intelligent Module provides direct conversion to Temperature. Internal or external Cold Junction Compensation Four alarm set-points per input Removable Terminal Blocks Hot Plug-in In system automatic module detection 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. Copyright Omniflex ♦ Subject to change without notice
