ABB DC551-CS31 | 1SAP220500R0001 | CS31 I/O Interface Module

Product Description

The DC551-CS31 (1SAP220500R0001) is a high-performance CS31 communication interface module with integrated I/O, engineered for ABB AC500/S500 automation systems. It functions as a CS31 slave, providing reliable digital input/output handling in compact, extendable form. This module supports small to medium distributed control applications while maintaining robust industrial reliability.

Key Features

• Integrated I/O eliminates the need for separate modules in smaller systems.

• 16 configurable digital channels allow flexible assignment as input or output.

• Extendable with up to 7 additional I/O modules for scalable setups.

• Compact DIN rail mount (15 mm or 7.5 mm) optimizes panel space.

• IP20-rated for industrial environments with continuous operation capability.

• Optional XC version available for harsh conditions (extreme temperature, humidity, dust).

Technical Specifications

Applications

Ideal for distributed I/O networks with ABB AC500 controllers. Suitable for machine automation, process monitoring, and modular I/O expansions. Particularly effective in setups requiring both digital input and flexible configurable outputs in a compact footprint.

FAQ

Q: Can the module handle high-current outputs?
A: The configurable channels support up to 0.5 A per channel; higher loads require external relays or output modules.

Q: Is it compatible with AC500 controllers only?
A: Yes, DC551-CS31 is designed for full compatibility with ABB S500 I/O and AC500 controller systems.

Q: What is the difference between standard and XC versions?
A: The XC variant provides additional coating for harsh environments with high humidity, dust, or temperature extremes.
