Description
ABB SPASI23 16-Channel High-Accuracy Analog Input Module
Product Overview
The ABB SPASI23 is a high-performance 16-channel analog input module designed for industrial automation systems, providing precise signal acquisition and processing for critical control applications. As part of ABB’s S800 I/O system, the ABB SPASI23 supports a wide range of input types, including thermocouples (TC), millivolts (mV), resistance temperature detectors (RTD), and high-level voltage/current signals, making it ideal for process control, energy management, and environmental monitoring910. Its compact design (73.66 mm x 360.68 mm x 269.24 mm) and robust construction ensure seamless integration into distributed control systems (DCS) and programmable logic controllers (PLC), even in harsh industrial environments with temperatures ranging from -20°C to +85°C29.
Engineered with a high-resolution ADC and 0.1% full-scale accuracy, the ABB SPASI23 delivers reliable measurement of signals such as temperature, pressure, and flow rate. Each channel supports configurable signal conditioning, including filtering and scaling, to optimize performance for specific applications. The module’s galvanic isolation (2500 V RMS) protects against electrical noise and ground faults, ensuring data integrity in noisy industrial settings910. With a fast conversion time of 250 µs per channel, it enables real-time monitoring and rapid control responses, critical for dynamic processes like power generation and manufacturing9.
The ABB SPASI23 features flexible communication options, including Modbus RTU and Profibus DP, allowing seamless integration with ABB’s AC800M controller and third-party systems215. Its DIN rail mounting and hot-swap capability simplify installation and maintenance, reducing downtime during module replacement. A self-diagnostic system continuously monitors internal components, providing early fault detection and detailed status reports via LED indicators or remote software1019.
