Millivolt, volt, and current
The universal module supports many input paths in order to support the
many different thermocouple, RTD, resistance, millivolt, volt, and millamp
input options. Thus the hardware/software errors of the system depends
greatly upon the input path.
The following table provides the maximum error for each voltage or
current input type when the module is operating at 25°C and was
calibrated at 25°C.
Input Max. Error
Type 25°C
± 50mV ±20 uV
± 100mV ±30 uV
± 0.5V ±0.3 mV
± 2.0V ±1.0 mV
0 to 5V ±2.5 mV
1 to 5V ±2.5 mV
0 to 10V ±5.0 mV
± 10V ±5.0 mV
4 to 20mA ±40 uA
0 to 20mA ±40 uA
The following table provides the maximum error for each voltage or
current input type when the module is operating at 0°C to 60°C and was
calibrated at that temperature.
Input Max. Error
Type 0°C to 60°C
± 50mV ±30 uV
± 100mV ±50 uV
± 0.5V ±0.5 mV
± 2.0V ±1.5 mV
0 to 5V ±4.0 mV
1 to 5V ±4.0 mV
0 to 10V ±8.0 mV
± 10V ±8.0 mV
4 to 20mA ±80 uA
0 to 20mA ±80 uA
