Brand: ABB
Model: DO820
Part No: 3BSE008514R1
Describe: Output module
Status: New/Used
DO820 is a digital output relay designed and manufactured by ABB, suitable for the field of industrial automation. It can convert the digital signals of the control system into switch output signals and output the signals to external devices through relays. This product has multiple switch output modes to meet different application requirements, with programmable switch output states for easy user control. It has high reliability, high precision, and high stability, and is widely used in various industrial fields such as manufacturing, energy, and utilities.
ABB DO820 (3BSE008514R1)
The DO820 is an 8 channel 230 V a.c./d.c. relay (NO) output module for the S800 I/O. The maximum output voltage is 250 V a.c./d.c. and the maximum continuous output current is 3 A. All outputs are individually isolated. Each output channel consists of optical isolation barrier, output state indication LED, relay driver, relay and EMC protection components. The relay supply voltage supervision, derived from the 24 V distributed on the ModuleBus, gives an error signal if the voltage disappears, and the Warning LED turns on. The error signal can be read through the ModuleBus. This supervision can be enabled/disabled with a parameter.
4) OSP sets outputs to predetermined state upon error detection
DO820是S800输入/输出的8通道230 V交流/直流继电器（NO）输出模块。最大输出电压为250 V交流/DC，最大连续输出电流为3 a。所有输出均单独隔离。每个输出通道由光隔离屏障、输出状态指示LED、继电器驱动器、继电器和EMC保护组件组成。继电器电源电压监控来自模块总线上分配的24V，如果电压消失，则会发出错误信号，警告LED会亮起。错误信号可以通过模块总线读取。可以通过参数启用/禁用此监督。
特性和优势
1） 230V交流/直流继电器常开（NO）输出的8个通道
2） 8个隔离通道
3） 输出状态指示器
4） OSP在检测到错误时将输出设置为预定状态
