The remote S900 I/O system can be installed in non-hazardous

areas or directly in Zone 1 or Zone 2 hazardous area depending on

the selected system variant. S900 I/O communicates with the

control system level using the PROFIBUS DP standard. The I/O

system can be installed directly in the field, therefore the costs for

marshalling and wiring are reduced.

The system is sturdy, error-tolerant and easy to service. Integrated

disconnection mechanisms allow replacement during operation,

meaning that there is no need to interrupt the primary voltage in

order to exchange the power supply units.

S900 I/O type N. For installation in safe (= non-hazardous) area.

Benefits

Preventive Maintenance creates value over the long-term by:

−Providing the best management of maintenance costs, in particular:

−  Less expensive direct costs of urgent, reactive maintenance

− Less expensive indirect costs of plant  shut-down, taking advantage of the scheduled stops

− Ensuring better efficiency and reliability of the plant

− Extending the circuit-breaker’s life

− Guaranteeing plant safety for a longer time Preventive Maintenance Program

ABB has designed maintenance schedules for all circuit breaker families,

based on technical knowledge of the products and on experience in the field.

The Preventive Maintenance Program has the following main targets:

− Check the preservation and the efficiency status of the apparatus

− Anticipate the trend  of deterioration of the circuit breakers, signalling

the need of replacement for excessively worn out components, or suggest alternative

solutions for bringing them up to date.

Maintenance Schedule

ABB created a systematic and functional Preventive Maintenance Program.

Besides the ordinary maintenance activities described in the air circuit breaker manual,

ABB proposes a maintenance intervention every three years directed to extend the product’s life.

(Extraordinary Maintenance). Service intervals shall have to be suitably assessed in case of

non-standard service and environmental conditions.

In order to guarantee high levels of efficiency and reliability to your electrical plant,

ABB suggests regular Preventive Maintenance on your installed air circuit breakers.

Preventive Maintenance on air circuit breakers includes testing, measurements and

maintenance, and repair or replacement activities.

These activities are based on specially designed technical plans, aimed at reducing the

probability of failure or the working deterioration of the apparatus.

ABB, a leader in the design and production of low voltage air circuit breakers,

always pays particular attention to customer satisfaction.

Thanks to its highly qualified organization, ABB Low Voltage Service provides

support to its customers during all phases of the product’s life,

from the selection to the after sales assistance.

Select I/O is an Ethernet networked, single-channel granular I/O system for the

ABB Ability™ System 800xA automation platform.Select I/O helps decouple project tasks,

minimizes the impact of late changes, and supports standardization of I/O cabinetry

ensuring automation projects are delivered on time and underbudget. A Signal Conditioning
