ABB SPASI23 Analog Input Module 16 channel
Description:
SPASI23 is ABB Symphony Plus control system Analog Input Module. As a Harmony rack I/O module, SPASI23 has 16 analog input channels that interface isolated thermocouple, millivolt, RTD, and high level analog signals to a controller with an analog-to-digital conversion resolution of 24 bits. Each channel has its own analog-to-digital converter and can be independently configured to handle the desired input type. These analog inputs are used by a controller to monitor and control a process. The controller performs the control functions; I/O modules provide the input and output functions.
SPASI23 can be used as a direct replacement for the IMASI03 or IMASI13 modules with only minor modifications. Changes to specification S11 in function code 216 are required to handle the differences in resolution choices. Verification of power supply sizing calculations and system current requirements could be necessary because of the change in power consumption.
SPASI23 module is fully compatible with existing INFI90® OPEN Strategic nterprise Management Systems.

Features:
The design of the SPASI23 module allows for flexibility in creating a process management system.
SPASI23 module conditions (filters, converts, and isolates) up to 16 analog input signals
SPASI23 module converts analog signals to digjital values, adds compensation and corections as needed, andprovides digital values to the controller through the l/O expander bus.
Each channel is individually programmabe for the following input types:
B, E, J, K, L,N (14 AWG),N (28 AWG),R,S,T.U thermocouples.
Chinese type E and Chinese type S thermocouples.
-100 to +100 millivolt.
Three-wire RTD(10,100 U.S.,100 European, 120 and Chinese 53 ohm).
-10 to +10 VDC high level voltage.
4 to 20 milliampere current
Resolution of the analog-to-digital conversion process is 24 bits
Input type and channel resolution can be selected independently for each channel, permiting any mix of inputs ona single ASl23 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. Thesemeasurements provide eror compensation during normal operation. The analog input module does automaticrecalibration during normal operation to compensate for component aging and temperature drift. No usercalibration is ever required.
Engineering units conversion to degrees C or F is automatically calculated on all input signals that arethermocouple or RTD types. These conversions correct for nonlinearities in the conversion to temperature unitsusing industry standard linearization tables.
The analog input module scales the block output value to engineering units for low and high level voltage inputsInput type, and zero and span values are specfied in FC 216.
Thermocouple inputs have cold junction compensaton. Each termination device has a built-in cold juncionreference. The cold junction reference applied to thermocouple inputs can be this built-in reference or it can be aremote reference read from another input from this or another l/O module.
SPASI23 module can be removed or installed without tuming off power to the system.
