ABB SPASI23 Analog Input Module

ABB SPASI23 analog input module is a Harmony rack I/O module, part of the Symphony enterprise management and control system. It has 16 analog input channels that connect isolated thermocouples, millivolts, RTDs, and high-level analog signals to the controller with 24-bit analog-to-digital resolution. Each channel has its own analog-to-digital converter and can be independently configured to handle the required input type.The following is a detailed description of the ABB SPASI23 Analog Input Module:

Fuctions & Features

• Channels: 16 channels, allowing multiple signals to be input simultaneously.

• Signal Type: ABB SPASI23 supports a variety of input types, including thermocouples (TC), millivolt (mV) signals, and resistance temperature detectors (RTD).

• Thermocouples (TC): ABB SPASI23 measures temperature with thermocouples, suitable for high temperature environments.

• Millivolt (mV): Measures low-voltage signals in the millivolt range, which can be used for various sensor outputs.

• Resistance Temperature Detector (RTD): ABB SPASI23 uses RTD to measure temperature and provide temperature readings.
