3.24.1 26-0* Analog I/O Mode
Parameter group for setting up the analog I/O configuration.
The option is equipped with 3 analog inputs. These analog
inputs can be freely allocated to either voltage (0V - +10V), Pt
1000 or Ni 1000 temperature sensor input.
26-00 Terminal X42/1 Mode
Option:
Function:
Terminal X42/1 can be programmed as an
analog input accepting a voltage or input from
either Pt1000 (1000
Ω
at 0
°
C) or Ni 1000 (1000
Ω
at 0
°
C) temperature sensors. Select the
desired mode.
Pt 1000
, [2] and
Ni 1000
[4] if operating in
Celsius - Pt 1000 [3] and Ni 1000 [5] if operating
in Fahrenheit.
Notice: If the input is not in use, it must be set
for Voltage!
If set for temperature and used as feed back,
the unit must be set for either Celsius or
Fahrenheit (
