Product Description

The SPCIS22 is a high-performance control input/output interface module designed for ABB’s Symphony Plus and Harmony rack-based control systems. It offloads real-time discrete logic execution from the central controller by handling local I/O scanning, interlocking, and command sequencing directly within the I/O chassis. This distributed intelligence architecture reduces system latency and enhances reliability in mission-critical applications such as thermal power plants, water/wastewater facilities, and industrial process skids.

Unlike basic I/O modules, the SPCIS22 integrates embedded processing capabilities that allow it to evaluate field inputs (e.g., limit switches, valve feedback, motor status) and drive outputs (e.g., solenoids, contactor coils) based on preloaded logic—without waiting for host CPU cycles. This makes it ideal for fast-response safety interlocks or equipment sequencing where deterministic timing is essential.

Technical Specifications

Manufacturer: ABB
Model / Part Number: SPCIS22
Compatible Systems: Symphony Plus, Harmony I/O, and legacy INFI 90 (with appropriate backplane and firmware)
Module Type: Intelligent Control I/O Interface (Discrete)
Mounting: Single slot in standard Harmony Module Mounting Unit (MMU)
Power Supply: +5 VDC via system backplane (no external power required)
Operating Temperature: 0 °C to +70 °C
Relative Humidity: 5% to 95%, non-condensing
I/O Capacity: Typically supports up to 16 digital inputs and 16 digital outputs (configuration-dependent)
Input Type: 24 VDC dry/wet contacts, compatible with relay or solid-state signals
Output Type: Relay or transistor-based (depending on sub-variant; verify ordering code)
Isolation: Galvanic isolation between field side and system logic (≥500 Vrms)
Response Time: < 10 ms typical for input-to-output logic execution
Diagnostics: Front-panel LEDs for module status, communication health, and per-channel I/O activity
Communication: Backplane-connected to Harmony Controller via high-speed parallel bus

Typical Applications

Boiler feed pump interlocks in fossil fuel power stations
Emergency shutdown sequences in water treatment clarifiers or filters
Localized motor control centers requiring autonomous start/stop logic
Retrofit projects integrating legacy INFI 90 I/O into Symphony Plus architectures

FAQ
Q: Is the SPCIS22 a standalone controller?
A: No—it operates as an intelligent I/O slave under the supervision of a Harmony or AC 800M controller but can execute preprogrammed discrete logic independently for speed-critical functions.

Q: Can it replace older INFI 90 IMDSI modules?
A: Functionally, yes—in many cases the SPCIS22 serves as a modern equivalent with enhanced diagnostics and faster response, though wiring and configuration must be validated during migration.

Q: Does it support hot-swap?
A: Yes, when installed in a Harmony rack with hot-swap enabled in system configuration. The module reports presence and readiness via the backplane protocol.
