ABB | DI880 3BSE028586R1 | High Integrity Digital Input

Product Description:

The DO880 is a 16 channel 24 V digital output module for single or redundant application. The maximumcontinuous output current per channel is 0.5 A. The outputs are currentlimited and protected against over temperature. Each output channel consists of a current limited and over temperature protected high side driver, EMC protection components, inductive load suppression, output state indication LED and an isolation barrier to theModulebus. 

16 channels for 24 V d.c. current sourcing outputs in one isolated group
Redundant or single configuration Loop monitoring, supervision of short and open loadwith configurable limits . Diagnostic of output switches without pulsing on outputs Advanced on-board diagnostics Output status indicators (activated/error)
Degraded mode for normally energized channels (supported fromDO880 PR:G)
Currentlimitation at short circuit and over-temperature protection of switches
Faulttolerance of1(as defined in IEC 61508) for output drivers.
For ND (Normally De-energized) systems, outputs can still be controlledwith error on output drivers Certified for SIL3 according to IEC 61508 Certified for Category 4 according to EN 954-1.
