ABB DO820 3BSE008514R1 Digital Output
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.
The ABB DO820 is a digital output module suitable for a variety of industrial automation control scenarios.
Application Scenarios
ABB DO820 is widely used in various industrial automation control scenarios, such as PLC control system, robotics system and so on. It can provide stable digital output signals and is suitable for industrial applications requiring high reliability and performance.
