Description

The ABB 07DC91 is a digital input/output module designed for use as a remote module on the CS31 system bus. This versatile module features 32 channels, including 16 digital inputs, 8 digital outputs, and 8 configurable inputs/outputs, all operating at 24 V DC. The configurable channels can function as inputs, outputs, or re-readable outputs, providing flexibility for various industrial applications. The module is built to ensure reliable performance, with features such as transistor outputs protected against overload and short circuits, and electrical isolation of the system bus connection from the rest of the unit.

Features

• 32 Channels: Includes 16 inputs, 8 outputs, and 8 configurable inputs/outputs.
• Transistor Outputs: Outputs have a rated load capacity of 0.5 A and are protected against overload and short circuits.
• Configurable I/O: The 8 configurable channels can be individually set as inputs, outputs, or re-readable outputs.
• Electrical Isolation: System bus connection is electrically isolated from the rest of the unit.
• Diagnostic Functions: Comprehensive diagnostics for fault detection (see "Diagnosis and Displays" chapter).
