Ordering A Cpu Module As Spare; Irda Interface; Pt100 Inputs - INTEGRA Metering CALEC energy master Installation And Operating Instructions Manual

22.2.3 Ordering a CPU module as spare

When ordering a CPU module as spare, please order the version that corresponds to the device con-
cerned. The corresponding module can be distinguished by its desiganation as shown in the example
below:
Device designation
EM-101-Prot-AC[...I]C-T
EM-100-Prot-AC[...I]C-T

22.2.4 IrDA interface

The IrDA interface on the CPU module can be used for temporary communication with a PC, e.g. for
reading the meter data or service operations. The IrDA interface can also be used with a mounted
display enclosed in the protective housing.

22.2.5 Pt100 inputs

Platinum resistance temperature sensors with 2, 3 or preferably 4 wire systems can be connected to
the Pt100 inputs. The temperature measurement is made via a 24 bit AD converter of high accuracy
and measuring consistency. Only a short current pulse flows through the measuring resistors, which
keeps the self-heating of the measuring resistor negligibly small.
Important!
the temperature difference.
The settings of the Pt100 inputs are effected via the submenu Basic setting/Pt100 input:
