Product Overview

DO880 is a product designed for ABB Ability ™  System 800xA ®  The 16 channel 24V digital output module is suitable for single or redundant configuration scenarios. It has powerful functional features and reliable performance, designed to meet the diverse needs of industrial automation control.

Core functions and advantages

Channel and output characteristics: It has 16 channels and outputs in 24V DC current source mode, with a maximum continuous output current of 0.5A per channel. Each channel is equipped with current limiting and over temperature protection functions, as well as integrated EMC protection components, inductive load suppression circuits, output status indicator LEDs, and isolation barriers to the Modulus, ensuring stable and reliable output.

Diagnosis and monitoring function: Supports circuit monitoring, can supervise load short circuits and open circuits, and the monitoring limits can be configured. Diagnosis of output switch status without the need for pulse output, with advanced onboard diagnostic function. At the same time, it has an output status indicator light (indicating active/error status), and supports degraded mode for normally powered channels (DO880 PR: G onwards).

Safety certification and reliability: The output driver has a fault tolerance of 1 (compliant with IEC 61508 standard), and in non excited (ND) systems, even if the output driver encounters errors, the output can still be controlled. This module has passed SIL3 certification of IEC 61508 and Class 4 certification of EN 954-1, with high reliability and safety.

Technical parameter details

Electrical parameters: The isolation method is inter group to ground isolation, and the output has short-circuit protection and current limiting functions. The maximum on-site cable length is 600 meters, with a rated insulation voltage of 50V and a dielectric test voltage of 500V AC. The power dissipation is 5.6W, and the current consumption outside the+5V Modulus,+24V Modulus, and+24V is 45mA, with a maximum of 50mA and 10mA, respectively.

Diagnostic and monitoring parameters: The front panel is equipped with F (fault), R (operation), W (warning), and 1-16 channel status/error indicator lights. The process power of each channel can be configured, and the loop resistance for loop supervision can be configured between 50 Ω and 2k Ω. The internal circuit can indicate module errors, module warnings, and internal channel errors.
