ABB DO820 3BSE008514R1 Digital Output Relay 8 Ch

• ABB DO820 3BSE008514R1 is an 8-channel digital output relay module for S800 I/O. Its output is a normally open (NO) type, suitable for 230V AC/DC voltage, with a maximum output voltage of 250V AC/DC and a maximum continuous output current of 3A.

• All output channels are individually isolated, each channel contains an optical isolation barrier, output status indicator LED, relay driver, relay and EMC protection components.

• The relay supply voltage is monitored by the 24V power supply on the ModuleBus. When the voltage is abnormal, an error signal is issued, the warning LED lights up, and this monitoring function can be turned on or off by parameters.

• DO820 has 8 channels, each channel can output 230V AC/DC voltage, using normally open (NO) type relay output.

• DO820 has 8 channels isolated from each other.

• DO820 has output status indicators to show the output status of each channel.

• DO820 has OSP (Output State Protection) function, which can set the output to a preset state when an error is detected.
