The Carbo 1001 performs as a measurement transducer for use with a wide range of sensors to determine the residual oxygen and calculate the C-level at the L-sensor, the O2- sensor, and the CO2 analyzer. The Carbo 1001 processes the incoming signals from all sensors in the system, calculates the desired baseline value, and stores these data in a predefined or symbolized data block in the PLC (programmable logic controller). Data blocks are used to set the configuration and error processing for the Carbo 1001. This makes it easy to integrate the Carbo 1001 into existing programs and to further process the obtained data. The Carbo 1001 communicates directly via the “Siemens Backplane Bus Protocol”, thus allowing the use of the PLC from the Siemens Simatic S7-300 family of products. There is no need for additional components! Despite the compact design of the Carbo 1001, we have still been able to achieve galvanic isolation between all input and output circuits. The Carbo 1001 is ready for use in an oven zone or it may be extended by up to five modules inside a longer housing.
