ABB数字量输出模块 DO880 3BSE028602R1

DO880是一款16通道24v数字输出模块，适用于单个或冗余应用。每通道最大连续输出电流为0.5 A。输出电流受限，防止过温。每个输出通道由电流限制和过温保护的高侧驱动器、EMC保护组件、感性负载抑制、输出状态指示LED和模块总线隔离屏障组成。

特点和好处

16通道24v dc电流源输出在一个孤立的组

冗余或单一配置

回路监测，具有可配置限制的短负荷和开负荷的监督(见表97)。

诊断输出开关没有脉冲输出

先进的机载诊断

输出状态指示器(激活/错误)

正常通电通道的降级模式(由DO880 PR:G支持)

短路限流和开关过温保护

输出驱动器的容错性为1(根据IEC 61508的定义)。对于ND(正常断电)系统，输出仍然可以控制输出驱动器上的错误

根据IEC 61508的SIL3认证

根据EN 954-1认证为4类

The DO880 is a 16-channel 24v digital output module suitable for single or redundant applications. The maximum continuous output current per channel is 0.5A. The output current is limited to prevent overtemperature. Each output channel consists of current limiting and overtemperature protected high side drivers, EMC protection components, inductive load suppression, output status indicator leds and module bus isolation barriers.

Features and benefits

16 channel 24v dc current source outputs in an isolated group

Redundant or single configuration

Loop monitoring, short load and open load supervision with configurable limits (see Table 97).

The diagnostic output switch has no pulse output

Advanced on-board diagnostics

Output status indicator (Activation/error)

Degraded mode for normally powered channels (supported by DO880 PR:G)

Short-circuit current limiting and switch overtemperature protection

The fault tolerance of the output driver is 1(as defined by IEC 61508). For ND(normal power off) systems, the output can still control errors on the output drive

SIL3 certification according to IEC 61508

Certified Category 4 according to EN 954-1
