ABB I/O Systems‑S900 I/O ABB Ability™ System 800xA® hardware selector

Product positioning and core features

Application scenarios specifically designed for ATEX Zone 1/Zone 2 hazardous areas with explosive gases present; Typical industries: chemical, pharmaceutical, oil and gas. IO modules can be directly installed in hazardous areas, reducing long-distance on-site wiring, eliminating the need for additional signal isolation safety barriers, and lowering wiring and signal conditioning costs.

The entire S900 supports a complete redundancy architecture, including power redundancy, communication interface redundancy, and PROFIBUS-DP bus link redundancy, to enhance system availability.

Features

Rich diagnostic functions;

Support HART intelligent field instrument communication;

Support SOE event sequence recording;

Wide working temperature range, special coating, suitable for harsh environments;

Reduce the workload of maintenance throughout the entire lifecycle.

ABB provides an online hardware selector website called 800xahardwareselector.com, which can compare AC800M controllers S800 I/O、S900 I/O、 Export PDF selection documents for hardware such as terminal units, networks, and power supplies. The complete technical parameters of the module need to be viewed on this website.

Analog input module series (models listed in the manual)

All modules have uniform mechanical dimensions: width 20   mm x depth 104   mm x height 104   mm; weight approximately 0.125-0.14   kg; 4 channels, signal type 4-20   mA. Suffix meaning:

– B: Intrinsic safety (suitable for Zone 1)

– N: Non explosion proof ordinary version

– S: Ex intrinsic safety explosion-proof version

– H: Supports HART protocol

WEEE：DIRECTIVE/2012/19/EU， Compliant with the EU Waste Electrical and Electronic Equipment Regulations.

Simple distinction from S800 I/O (combined with the background of the previous 800xA document)

S800 I/O: Conventional remote I/O, used in safe areas (non explosion proof);

S900 I/O: ATEX intrinsically safe explosion-proof remote I/O, can be directly placed in Zone 1/Zone 2 hazardous sites, suitable for chemical oil and gas explosion-proof projects, supports PROFIBUS-DP redundancy HART、SOE。
