Features:
- Provides 8 dedicated digital inputs together with 16 configurable digital input/output channels to accommodate different control requirements.
- Supports connection of up to seven additional I/O modules for scalable CS31 automation systems.
- Features galvanic isolation from the CS31 bus, configurable input delay from 0.1 ms to 32 ms, and LED indication for every digital input channel.
ABB DC551-CS31 1SAP220500R0001 serves as an interface between the CS31 communication network and distributed field signals in S500 automation systems. By combining communication capability with integrated digital I/O, the module reduces system complexity while supporting efficient signal acquisition and control. Its expandability also makes it suitable for installations that may require future capacity increases.
The module accepts 24 V DC digital input signals according to EN 61131-2 Type 1 and provides transistor outputs rated at 24 V DC with an output current of 0.5 A. Adjustable input delay allows optimization for fast or stable signal processing, while dedicated LED indicators simplify diagnostics during operation and maintenance. These features contribute to dependable performance in industrial control applications.
ABB DC551-CS31 1SAP220500R0001 is intended for installation in protected control cabinets with an IP20 enclosure rating. Operating from a 20.4 to 28.8 V DC supply, it performs reliably within an ambient temperature range of 0°C to +60°C and can be stored from -40°C to +70°C. The combination of CS31 communication, configurable digital I/O, and modular expansion makes it well suited for manufacturing, process automation, and machine control systems.
The DC551-CS31 1SAP220500R0001 ABB CS31 Communication Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
