配置模式：支持冗余或单一配置，对于ND（常断电）系统，即使输出驱动器存在误差，仍可对输出进行控制。正常通电通道还具有降级模式（从DO880 PR:G开始支持）。
The ABB DO880 is a digital output module for System 800xA.Product details are as follows:
Basic Parameters
Number of Channels:16.
Output Voltage:24V DC.
Output Current:Maximum continuous output current per channel is 0.5A.
Isolation:16 channels are grouped together,isolated from ground.
Rated Isolation Voltage:50V.
Insulation Test Voltage:500V AC.
Current Draw:45mA from the+5V module bus and 10mA from an external+24V supply.
Maximum Field Cable Length:600m.
Features
Protection:Each output channel features a current-limiting and thermally protected high-side driver to protect against short circuits and overtemperature conditions,ensuring stable and reliable output.Additionally,the module is equipped with EMC protection components,inductive load suppression,and a module bus isolation barrier,enhancing system noise immunity and safety.Monitoring and Diagnostics:Supports loop monitoring,capable of monitoring short-circuit and open-circuit loads with configurable limits.It also provides pulseless output switching diagnostics and advanced onboard diagnostics to help promptly identify and resolve problems.
Status Indication:LED output status indicators display channel activity or error status,providing intuitive visibility into module operation.
Certification:Certified to SIL3 under IEC 61508 and Category 4 under EN 954-1,it offers high safety and reliability.
Configuration Mode:Supports redundant or single configurations.For ND(normally powered-off)systems,output control remains active even if output driver errors occur.Normally powered channels also feature a degraded mode(supported starting with the DO880 PR:G).
