The ABB SPICT13A, SPICI03 SCIL, SPHSS13, SPHSS03, SPFEC12, and SPFCS01 represent a versatile and high performance selection of INFI NET based communication, hydraulic servo control, and frequency measurement modules, engineered for the ABB Symphony and Bailey INFI 90 distributed control systems (DCS). As a globally respected brand in industrial automation, ABB designs each of these modules to deliver precision, durability, and seamless integration into demanding applications such as steam and gas turbine governing, hydroelectric plant control, paper machine drives, and high speed metal rolling mills. Together, these modules provide plant engineers and system integrators with the essential building blocks for expanding, maintaining, or upgrading legacy INFI 90 installations as well as modern Symphony Plus architectures.

The ABB SPICT13A (INFI NET to Computer Transfer module) serves as a high speed gateway between the deterministic INFI NET control network and external computer systems. This module enables data exchange with plant historians, optimization servers, and third party HMIs using ABB’s proprietary transfer protocol. The ABB SPICT13A supports both peer to peer and master slave communication modes, making it an indispensable tool for facilities that require real time process data access from centralized IT infrastructure without compromising the determinism of the INFI NET backbone.

Complementing the SPICT13A, the ABB SPICI03 SCIL (INFI NET to Computer Interface) provides an alternative or redundant computer interface solution. This module is specifically configured for serial communication links, supporting RS 232, RS 422, and RS 485 physical layers. The ABB SPICI03 SCIL is often deployed in legacy systems where direct computer connectivity over long distances is required, and it includes diagnostic LEDs for link status and data activity.

For hydraulic actuator control in critical turbine and valve applications, the ABB SPHSS13 Hydraulic Servo Module delivers high resolution analog output with integrated position feedback processing. This module accepts LVDT or similar position sensor inputs and generates a proportional current output (typically 4‑20 mA or ±10 V) to drive servo valves controlling steam inlets, fuel valves, or water gates. The ABB SPHSS13 is designed for single loop applications where fast response and precise positioning are mandatory.

When redundant hydraulic control is required for safety critical or high availability systems, the ABB SPHSS03 Redundant Hydraulic Servo Module provides the same core functionality but with built in redundancy management. Two ABB SPHSS03 modules can be configured in active standby or load sharing mode, with automatic bumpless transfer upon failure detection. The ABB SPHSS03 is widely used in emergency shutdown valves, turbine overspeed protection systems, and other safety instrumented functions where a single point of failure cannot be tolerated.

The ABB SPFEC12 Module is a multifunctional event capture and logic engine that operates as a high speed sequence of events (SOE) controller. It monitors digital input state changes with sub millisecond resolution and timestamps them against a system wide clock reference. The ABB SPFEC12 works in conjunction with ABB time synchronizing modules to provide forensic quality data for fault analysis, especially in power substations and fast process interlocks.

Finally, the ABB SPFCS01 Frequency Counter Module accepts one dedicated high speed input for measuring frequency from turbine speed probes, flowmeters, or rotational encoders. The input channel is galvanically isolated and can handle signals from magnetic pickups, proximity probes, or TTL level pulses. The ABB SPFCS01 calculates frequency, period, or pulse count with an accuracy of 0.01 percent, making it ideal for overspeed detection, rotational speed monitoring, and flow totalization in custody transfer applications.

All six ABB modules share a common mechanical and electrical design philosophy. They mount directly into standard Symphony or INFI 90 I/O racks (such as the ABB INICT or NPR series), connect to the INFI NET backplane for data and power, and are configured using ABB’s Composer or Control Builder engineering tools. Each module features front panel LEDs for power, communication, and channel status, enabling rapid troubleshooting without requiring external diagnostic equipment.

For maintenance managers and reliability engineers, these genuine ABB spare parts ensure long term operability of existing INFI 90 and Symphony systems. The ABB SPICT13A and SPICI03 SCIL provide critical data pathways for modernizing older control rooms. The ABB SPHSS13 and SPHSS03 offer reliable hydraulic servo control with optional redundancy. The ABB SPFEC12 captures high speed events, while the ABB SPFCS01 delivers precise frequency measurement. Backed by ABB’s global quality certifications and decades of field proven performance, this module set is the trusted choice for sustaining and enhancing your DCS infrastructure.
