I/O Modules For Resistance Measuring - WAGO 750 Series Manual

2.1.2.7.3 I/O Modules for Resistance Measuring

Resistance measuring
750-461/000-002 Resistance measuring,
750-461/000-007 Resistance measuring,
The measured values are sent out directly when measuring the resistance.
Using the 750-461/000-002 module with measuring range from 10 Ω to
1.2 kΩ, the resolution is 1 digit per 0.1 Ω.
Using the 750-461/000-007 module with measuring range from 10 Ω to
5.0 kΩ, the resolution is 1 digit per 0.5 Ω.
Resistance measurement is only possible in 2-wire connection technology.
The analog input module transmits 16-bit measured values per channel as well
as 8 optional status bits to the coupler/controller.
Values marked with "ca." are not calibrated.
Values marked with "ca." are not calibrated.
