Safety
The tamper-proof recorded data are saved and can be transferred to an external SQL
database for archiving in a way that prevents subsequent manipulation.
15.2 Input
Measured values Number of analog universal inputs
Standard version without universal inputs. Optional input cards (slot 1-3) with 4 universal
inputs (4/8/12) each.
Number of digital inputs
6 digital inputs
Number of mathematics channels
4 mathematics channels (optional). Mathematics functions can be freely edited via a
formula editor.
Integration of calculated values e.g. for totalization.
Number of limit values
30 limit values (individual channel assignment)
Function of analog universal inputs
You are free to choose between the following measured variables for each universal input:
U, I, RTD, TC, pulse input or frequency input.
Integration of input variable for totalization e.g. flow rate (m
3
/h) in quantity (m
3
).
Calculated values
The values of the universal inputs can be used to perform calculations in the mathematics
channels.
Measuring range of analog
universal inputs
According to IEC 60873-1: An additional display error of ±1 digit is permitted for every
measured value.
User-definable measuring ranges per universal input of the multifunction card:
