Connections and functions

The following block circuit diagram shows the SEZ220 connections and function
blocks. The function blocks convert the signals to the inputs as per the
configuration and parameterization, and provide them via the outputs as
DC 0...10 V signals.

Element Explanation
X1...X5 Universal inputs for analog, passive, or active signals of various
measured values (°C, %, ---).
MIN-MAX-AVR Function block "Min-max-average".
SPLIT Configuration parameter. When active, the functions of MIN-
MAX-AVR are assigned to inputs X1 – X2 and X3 – X5.
ENTHALPY Function block "Enthalpy processor".
2X-INV Function block "Signal doubling / signal inversion".
Y1, Y2 DC 0...10 V outputs.
