IMASI03 说明

Used/refurbished, verified in good working condition. 

The design of the IMASI03 module, as with all INFI 90 modules, allows for flexibility in creating a process management system. Refer to the NOMENCLATURE entry of this section to see the list of devices that can be used with the slave module in an INFI 90 system. 

• The IMASI03 conditions (filters, amplifies and isolates) up to 16 analog input signals. 

• The IMASI03 converts analog signals to digital values, adds compensation and corrections as needed, and provides digital values to the MFP through the slave expander bus.30 money back guaranty unless completely satisfied, (1)

• Each channel is individually programmable for these input types: E, J, K, L, N (14 AWG), N (28 AWG), R, S, T, U thermocouples. Chinese type E and Chinese type S thermocouples. Millivolt (-100 to +100 mV). 3-wire RTDs (10, 100 U.S., 100 European, 120 and Chinese 53 Ohm). High level (-10 to +10 V). Current (4-20 mA). 

• Resolution of the analog-to-digital conversion process is programmable over a range from 16 to 24 bits. 

• Input type and channel resolution may be selected independently for each channel, permitting any mix of inputs on a single IMASI03 module.

 • Channel isolation and open input detection are provided for each channel. 

• Input circuit offset, gain and nonlinearity errors are recorded during a one time factory calibration procedure. These measurements provide error compensation during normal operation. The slave does automatic recalibration during normal operation to compensate for component aging and temperature drift. No user calibration is ever required. 

• Engineering units conversion to degrees C or F is automatically calculated on all input signals that are thermocouple or RTD types. These conversions correct for nonlinearities in the conversion to temperature units using industry standard linearization tables. 

• The slave scales the block output value to engineering units for low and high level voltage inputs. Input type and zero and span values are specified in function code 216.

 • Thermocouple inputs have cold junction compensation. Each termination device has a built-in cold junction reference. The cold junction reference applied to thermocouple inputs may be this built-in reference or it may be a remote reference read from another input from this or another slave. 

• The slave compensates for lead wire resistance in the connection between the thermocouple, RTD or low level voltage input signals. 

• The IMASI03 can be removed or installed without turning off power to the system.
