ABB S800 I/O Modules and Termination Units

ABB S800 I/O Modules and Termination Units 

The S800 I/O is distributed as modular I/O that communicates with numerous

controllers over Advant Fieldbus 100 (AF100), PROFIBUS-DP, or directly.

The S800 I/O provides easy installation of the I/O modules and process cabling.

It is highly modularized and flexible so that I/O modules can be combined to suit

many applications. The S800 I/O can be mounted in many configurations to fit most

requirements.

The S800 I/O provides easy installation of the I/O modules and process cabling.

It is highly modularized and flexible so that the I/O modules can be combined to suit

many applications, including most types of signals, HART and Intrinsic Safety

Interface. The S800 I/O modules and a Fieldbus Communication Interface (FCI) are

combined to form an I/O Station. The S800 I/O can be used in both single and

redundant applications.

In general, all S800 units are G3 compliant. G3 compliant modules withstand more

severe environmental conditions according to ISA-S71.04. The following S800

units are G2 compliant - SD821, SD822, SD823, SD831, SD832, SD833, SD834,

SS822, SS832, TB811 and CI830. G3 compliant versions of SD822 and SS822 are

also available (refer to SD822Z and SS822Z).

All modules are marked with a bar code that shows the serial number, article ID and

the product revision number. A separate bar code strip is also enclosed along with

the module for placing on the module, if needed. The bar code is of type

Bar-code 128.

For more information, refer to S800 I/O Getting Started(3BSE020923*) manual.

The S800 I/O can be categorized into:

•Module Termination Units (MTU)

•I/O modules – S800 I/O modules and S800L I/O modules.

S800 I/O modules are designed to be used together with a Module Termination

Unit.

S800L I/O modules are designed to be directly mounted on a standard DIN rail.

The module also contains terminals for connections.

Module Termination Units and Terminal Units

The Module Termination Units (MTU) are passive base units used to house the I/O

modules. They contain the process wiring terminals and a section of the

ModuleBus.

The Module Termination Units (MTU) distributes the ModuleBus to the I/O module

and to the next MTU. It also generates the correct address to the I/O module by

shifting the outgoing position signals to the next MTU.

Two mechanical keys are used to configure the MTU for different types of I/O

modules. This is only a mechanical configuration and it does not affect the

functionality of the MTU or the I/O module. Each key has six positions, which gives

a total number of 36 different configurations. The configuration can be changed

with a screwdriver.

The MTU can be mounted on a standard DIN rail. It has a mechanical latch that

locks the MTU to the DIN rail. The latch can be released with a screwdriver.

The MTU has a mechanical locking mechanism that locks the module in its

position. This mechanism also gives the signal BLOCK to the I/O module that

keeps the module in its init state until it is locked in its position.

The top part of the MTU can be removed to replace the termination board even with

the system running. Such a need can be caused by a damaged terminal screw.

The MTUs are available in tree versions (Compact, Extended and Redundant).

The Compact MTU version typically provides for a compact installation of the I/O

modules using 1 wire connections.

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.
