A data gathering panel is disclosed for converting analog values into digital values having input terminals for connection to analog sensors, a memory for storing a base value and a range value associated with the sensor, a base circuit connected to the memory for applying the base value to the analog value, and an analog-to-digital converter using the analog value, the base value and the range value for converting the analog value into a digital value. The data gathering panel may also permit connection to a plurality of input sensors having different characteristics by providing a memory for storing the different characteristics of the input sensors to be used by a processor in processing the information derived from the sensors. This memory may be a programmable read-only memory and the data gathering panel may have a facility thereon for allowing the altering of information stored in the programmable read-only memory.
