SBS IOM I/O-Fieldbus module
OPEN BUILDING AUTOMATION
The open MODBUS I/O SYSTEM
The SBS-IOM series consists of compact fieldbus modules with inputs and outputs for mounting on DIN rails, on the mounting plate in the control cabinet or electrical distributor or in the 19" rack, for mounting on the door.
SBS / Smart Building Solutions
With our SBS series we offer IoT solutions and services that go far beyond the usual room and building automation.
General Information
General Information
- Binary, digital and analogue signals are recorded, output and processed in the automation stations (Niagara platforms) at various points in the building and the building services systems via the SBS-IOM devices.
- The connection with the automation station takes place via a commercial RS 485 communication bus / MOD bus RTU
Local Override (LO)
Local Override (LO)
- The OAS-SBS-IOM series meets the requirements of the local override operation (LO) according to DIN EN ISO 16484 and VDI 3814.
- The manual and emergency operation for overriding the outputs of the automation station is carried out via switches and potentiometers as operating elements, which complies with DIN EN ISO 16484 and VDI 3814 for LO
- Status messages of the inputs and outputs are transmitted by LEDs.
- the function of the operating elements is also possible without bus communication (emergency operation)
- the LO control elements functionally replace conventional switches and signal lamps in conventional control cabinets and electrical distribution boards
Communication / MOD-BUS RTU
Communication / MOD-BUS RTU
- MOD-Bus RTU is an open and globally proven standard that requires no investment in programming interfaces.
- The integration and communication with the automation station / Niagara platform takes place via a galvanically isolated RS 485 interface via / MOD bus RTU
- SBS IOM fieldbus modules work as MOD bus slaves on the MOD bus master (automation station).
- no further gateways required
OAS I/O WEB Module Configurator
OAS I/O WEB Module Configurator
- Any configuration of communication settings is conveniently and partially automated via the OAS I/O WEB Module Configurator on the Niagara automation platform.
- The configuration, monitoring and control of the inputs and outputs is implemented in automatic mode via the RS 485 interface.
