Product Description:

The BC9191-0100 is a Building Automation Room Controller which is dedicated for the purpose of Commissioning in Integration of the Design system and has wide ranging signal and communication facilities. The modem falls under the combination I/O classification. Couplers of this classification contain17 channels and the construction is capable of handling both analog and digital signals. In terms of digital signals, they are either 24 V of 230 V and regarding analog point of view supports 0 to 10 V (normal as per signal) and RTD Pt100/1000, KTY, resistance which is between 1 to 10 kOhm and less than 1 kOhm.

The output current of 1A, 10 Ampers and 120 volts AC or 230 volts AC have been within the tolerance of BC9191-0100 making it now possible to apply low voltage and high voltage devices. The device includes cellular communication modules such as Ethernet, K it is different protocol, Modbus RTU and RS485, RS422 supporting communication and remote data acquisition They are embedded into distribution networks, integrating into information systems. The bus interface supplies the distributed device 2 x RJ45 switched ports for connection to an ethernet network.

The room controller complements a PLC as such it can perform some of the functions that need the addition of control without adding more controls functional. For the digital signals, the input/output specification is potential free, allowing for safe non electrically connected isolation switching. Even when processing analog signals, the measurement resolution provided by the controller is limited to below 12 bits and measurement accuracy is more than 1%. The sampling rate is also less than 0.1 ksps and conversion time exceeds 10 milliseconds; this is ideal for systems that do not require high speed data acquisition.
