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.
