 ABB DO820 3BSE008514R1 Digital Output Module 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.Detailed data: Isolation Individual isolation between channels and circuit common Current limitation Current can be limited by MTU Maximum field cable length 600 m (656 code) Event logging accuracy -0 ms / +1.3 ms Rated insulation voltage 250 V Dielectric test voltage 2000 V AC Power consumption Typical 2.9 W +5 V module bus current consumption 60 mA +24 V module bus current consumption 140 mA +24 V external current consumption 0 Environment and certifications: Electrical safety EN 61010-1, UL 61010-1, EN 61010-2-201, UL 61010-2-201 Operating temperature 0 to +55 °C (+32 to +131 °F), approved from +5 to +55 °C Storage temperature -40 to +70 °C (-40 to +158 °F) Pollution degree 2, IEC 60664-1 Corrosion protection ISA-S71.04: G3 Relative humidity 5 to 95 %, non-condensing Maximum ambient temperature 55 °C (131 °F), 40 °C (104 °F) for compact MTU in vertical installationFrequently asked questions about the product are as follows: -What is the ABB DO820 module used for? The DO820 is a digital output module used to control discrete outputs in automation systems. It is an interface between the controller and field devices such as solenoid valves, relays or other actuators that require digital (on/off) signals. -What are the main specifications of the ABB DO820 module? The DO820 has 8 channels. It can support different output voltages (usually 24V DC) depending on the configuration. Each channel can support output currents ranging from 0.5A to 1A, depending on the model. It supports digital output signals (on/off) and is either source or sink depending on the configuration. Each channel is electrically isolated to ensure safety and protect the controller and field devices. -How is the DO820 module mounted and connected? It is mounted on a DIN rail or in a standard panel. It is designed to be connected to the I/O bus of the automation system, and the field wiring is connected to the terminal blocks of the module.
