Analogue input
The module uses 4 analogue inputs with a resolution of 12 bit and an input range of 0 V...3.0 V. The input range can be arbitrarily expanded with the help of external voltage dividers or amplifiers. Every single input is referenced to GND and has an input resistance of about 12.5 KΩ. The absolute accuracy is 11 bits, as reference 3.0 is used. This enables the display to measure analogue voltages, e.g. to display or save the values for further processing. The exceeding or undershooting of a threshold can also be used to trigger an alarm. The overview of the software commands for the analogue inputs can be found under the chapter 'Analogue Input' |
