ABB S800 I/O Modules and Termination Units

An electronic type designation ID in each module keeps the I/O module from being

taken into operation by the ModuleBus master, if a module’s ID doesn’t match the

configured module type definition.

Refer to specifications in Appendix A, Specifications for more information.

The module can be mounted on a standard DIN rail. The module is locked to the

DIN rail by using the locking screw.

The process connection is done via detachable connectors.

AI801 Analog Input Module, 0...20 mA

The AI801 Analog Input Module has 8 current inputs.

The current input is able to handle a short circuit to the transmitter supply without

damage. The input withstands HART communication.

Nominal input ranges are: 0(4)... +20 mA.

AO801 Analog Output Module, 0...20 mA

The AO801 Analog Output Module has 8 current outputs. State of outputs can be

set to a predetermined (OSP) value if a communications error is detected. Nominal

output range is: 0(4)... 20 mA.

DI801 Digital Input Module, 24 V, Current Sinking

The DI801 Digital Input Module has 16 channels for 24 volt d.c. digital inputs.

One input channel can be used for sensor voltage supervision. Each input channel

provides current limiting, EMC protection, input state LED indicator and optical

isolation from the ModuleBus.

DI802 Digital Input Module, 120 V a.c./d.c., Current Sinking

The DI802 Digital Input Module has 8 channels for 120 volt a.c./d.c. digital inputs.

Channel 8 can be used for sensor voltage supervision. Each input channel provides

current limiting, EMC protection, input state LED indicator and optical isolation

from the ModuleBus.

DI803 Digital Input Module, 230 V a.c./d.c., Current Sinking

The DI803 Digital Input Module has 8 channels for 230 volt a.c./d.c. digital inputs.

Channel 8 can be used for sensor voltage supervision. Each input channel provides

current limiting, EMC protection, input state LED indicator and optical isolation

from the ModuleBus.

DO801 Digital Output Module, 24 V, 0.5 V, Current Sinking

The DO801 Digital Output Module has 16 channels for 24 volt d.c., 0.5 A, digital

outputs. Each output channel provides protection against short circuits to ground,

over-voltage, over-temperature, EMC protection, output state LED indicator and

optical isolation from the ModuleBus. State of outputs can be set to a predetermined

(OSP) value if a communications lost error is detected.

DO802 Digital Output Module, 24-250 V, Relay Normally Open

The DO802 Digital Output Module has 8 channels for 24-250 volt d.c., digital

outputs. Each output channel provides protection against short circuits to ground,

over-voltage, over-temperature, EMC protection, output state LED indicator and

optical isolation from the ModuleBus. State of outputs can be set to a predetermined

(OSP) value if a communications lost error is detected.
