Specification

The ABB CI581-CN is a highly integrated S500 interface module designed to serve as a CANopen slave in distributed automation networks. This module combines 4 analog inputs (supporting voltage, current, and RTD signals), 2 analog outputs (voltage or current), 8 digital inputs at 24 VDC, and 8 digital outputs rated at 24 VDC and 0.5 A per channel. Its compact footprint and IP20 enclosure make it an excellent choice for space-constrained control panels in manufacturing, process, and building automation applications. With a supply voltage range of 20.4 to 28.8 VDC and a typical input current of just 5 mA, the CI581-CN delivers reliable performance while minimizing power consumption. This module is engineered for seamless integration into ABB’s S500 I/O system, offering a cost-effective solution for mixed-signal fieldbus connectivity.
