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.

Features and benefits

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 (see table Table 97).

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

輸出受到電流限制和保護(hù)

防止溫度過高。每個輸出通道由一個電流組成

有限和過熱保護(hù)的高側(cè)驅(qū)動器，EMC

保護(hù)組件、電感負(fù)載抑制、輸出狀態(tài)

指示LED和模塊的隔離屏障。

功能和優(yōu)點

一個隔離組中用于24 V直流電流源輸出的16個通道

冗余或單一配置

回路監(jiān)測，具有可配置限值的短負(fù)載和開路負(fù)載的監(jiān)督（見表97）。

輸出開關(guān)無脈沖的診斷

高級車載診斷

輸出狀態(tài)指示燈（激活/錯誤）

正常通電通道的降級模式（由DO880 PR:G支持）

開關(guān)短路電流限制和過熱保護(hù)

輸出驅(qū)動器的容錯率為1（如IEC 61508中所定義）。對于ND（正常斷電）

系統(tǒng)，輸出仍然可以通過輸出驅(qū)動器上的錯誤進(jìn)行控制
