Product Description:
The BC9191 is a useful coupler mostly used in the building automation systems applications with 17 combi channels providing for both digital and analog I/O. The equipment is appropriate in most value combinations, 24 V and 230 V digital and encoder signal, 0 – 10V analog signals and resistance measurement RTD Pt100 / 1000, KTY and 1kOhm to 10kOhms and less than 1kOhm. It accepts 1A and 10A output current at a rated voltage of 120 VAC or 230VAC.
The aforementioned equipment is capable of integration with building management and automation systems, as it supports communication protocols such as EnOcean, Ethernet and K-bus. The unit also incorporates data acquisition with a relay, the latter being free of normal openings and providing two or more potential free inputs and outputs to the digital signal with a standard time constant of 3.0 ms. The sampling of the electrical signals in the analog inputs is achieved in parallel with the signal resolution being less than twelve bits and the uncertainty in the measurement greater than one percent. Whereas the sampling and holding of the incoming and processed signal in the equipment is done at a rate of less than 0.1 ksps the conversion of the signal takes greater than cm of the circuitry.
The BC9191 introduces into synchronization and freeze synchronized command that makes use of Synch and Freeze order. Where a master requires to synchronize the outputs (Sync commands) or capture the inputs (Freeze command) through many slaves, these commands enable doing this.
