Product Overview

The ABB SPASI23 is a high-density, microprocessor-based Analog Slave Input Module engineered for the INFI 90 distributed control system architecture. It serves as an intelligent hardware bridge that interfaces directly with various external field transmitters, simultaneously scanning and digitizing multiple analog process signals. Designed to operate under a master controller module, it features an on-board analog-to-digital converter (ADC) that converts varying process current or voltage loops into precise digital data, allowing the master DCS processor to execute complex control loops without dealing with raw sensor conditioning.

(1) Channel Input Capacity: Supports up to 16 single-ended analog input channels or 8 differential input channels

(2) Signal Ranges: 4-20 mA current loops, 0-5V DC, 1-5V DC, and 0-10V DC voltage sweeps

(3) Logic Bus Current Draw: Draws approximately 400 mA from the +5V DC backplane logic line

(4) A/D Resolution: Utilizes a 12-bit analog-to-digital converter

(5) Operating Temperature Window: Formulated for standard industrial control cabinets, operating between 0°C to +60°C

(6) Storage Temperature Limits: Sturdy survival threshold from -20°C to +70°C

Industrial Applications

ü DCS Field Transmitters Interfacing: Directly captures real-time data loops from automated fluid pressure transmitters, ultrasonic level sensors, and flow meters.

ü Industrial Thermal Processing: Gathers continuous raw temperature voltage drops via conditioning amplifiers inside petrochemical and power grid substations.

ü Legacy Infrastructure Life Extension: Sourced globally as an essential direct-fit replacement part to keep active classic Bailey control racks operational without executing highly expensive system overhauls.
