Resistance Measurement 10 Ohm to 5.0 kOhm
The 750-461/000-007 version outputs the resistance values of the sensors
directly. The resistance values are displayed at a resolution of 1 digit per 0.5
Ω
in
one word (16-bit). The possible numeric range corresponds to the defined
measurement range of 10
Ω
to 5.0 k
Ω

Configurable I/O Module 750-461/003-000
Table 27: Configurable I/O Module
750-461/003-000
Default setting: Pt100 configurable
Measuring range: −
200 °C … +850 °C
The operating mode of the I/O module version 750-461/003-000 can be freely
configured using the WAGO-I/O-
CHECK
commissioning tool. The default setting
is Pt100. In this mode the I/O module has the same process values as the
standard I/O module 750-461.
The
WAGO-I/O-
CHECK
commissioning tool can be used to configure the
required operating mode. The I/O module can also be parameterized via
PROFIBUS and PROFINET device description (GSD file).
The parameterization description can be found in the appendix in Section
“Configuration and Parameterization via GSD File with PROFIBUS DP and
PROFINET IO.”
The parameter dialog in WAGO-I/O-
CHECK
presents optional fields for the
settings of this I/O module:
