Key Features

• Versatile AC Powering: The built-in 115/230 VAC power supply unit eliminates the need for an external DC transformer, simplifying the overall electrical cabinet design.

• Robust Relay Outputs: Features 12 relay outputs capable of switching up to 2A, allowing for direct control of contactors, solenoids, or small motors.

• CS31 Bus Expansion: Supports the CS31 system bus protocol, enabling the processor to master up to 31 remote I/O modules for decentralized automation architectures.

• Integrated Programming Interface: The COM1 port serves a dual purpose as both a programming interface (via 907 AC 1131 software) and an ASCII interface for HMI or printer connectivity.

• Self-Diagnostics: Constant monitoring of internal hardware and bus status with visual LED feedback for rapid troubleshooting.
