ABB S900 I/O Analog Module DX910B Digital Input or Output (DIO8-B)
3KDE175312L9100
Description of S900
S900 is a remote I/O system for mounting directly in the field and
hazardous areas.
S900 provides all input and output modules needed for intrinsically
safe field signal connection. The field signals are amplified in
every S900 functional module, electrically isolated, and then
output via an internal serial bus. A communication interface
converts the digitized signals to adapt them to the standardized
PROFIBUS DPV1 fieldbus protocol. Supervisory process control
systems, DCS or SCADA systems use an intrinsically safe fieldbus to
communicate with the communication interface.
A single fieldbus network suffices for configuring the individual
fieldbus nodes, for cyclic data exchange, for all acyclic services,
and for communication with HART®-compatible field instruments. All
functional modules can be replaced easily and quickly in the
installation or maintenance phase. The functional modules and the –
optionally redundant – communication interfaces of systems placed
in Zone 1 can be removed and plugged in while operation is running,
without affecting the communication of the remaining modules. Only
the primary power for the plug-in type power supply modules
requires increased safety EEx-e.
Integrated encapsulated switch-off mechanisms allow for
hotswapping, i.e. the power supply units can be replaced without
interrupting the primary power. Due to its little space
requirements and robust design and its environmentally ruggedized
case, the I/O system S900 is the best, cost-saving

Application
Ready-made, EExi/ATEX-certified high-grade steel housings and the
CB220 Compact Box for assembly in the field provide a wide range of
installation options.
Field housings – for wall-mounting in the case of installation in
Zone1 with a system approval fully certified in accordance with
ATEX. The stainless steel field housing is ready-wired and prepared
for wall-mounting. In addition, screen rails or terminals can be
mounted. Together with the field housing, this brings the following
advantages:
CB220 compact box – S900 remote I/O in compact form with up to 4 I/O modules for decentralized use in a compact housing. This variant is suitable, for example, for use in applications such as temperature multiplexers and solenoid controls. The CB220 compact box additionally offers the following advantages:
