Module variants
The analog input module is available in two variants:
D E ana w/ 8 isolated-potential differential inputs
D E20 ana w/ 8 power inputs, current rated.
12.1.1 E ana Analog Input Module
The E ana analog input module provides:
D 8 Isolated-potential differential inputs
D 16-bit resolution at 13-bit linearity
D Individually selectable measuring range for all inputs
D Integration of measured values via numerical measurements
D Sensor failure and overrange monitoring
D Voltage measurement in 4 measuring ranges
D Current measurement in 2 measuring ranges
D Temperature measurement via thermocouple
D Characteristic curve correction
D compensation
D Conversion to _C
D Temperature measurement via resistance thermometer
D Four 2.5 mA stabilized power sources
D Characteristic curve correction
D Conversion to _C
Thermocouples
The E ana analog input module supports the following thermocouples defi-
ned in the IEC 584 standard: Type B, E, J, K, R, S, T
Both non-floating and potential–free thermocouples with two-wire connec-
tions can be connected.
Resistance thermometers
The E ana supports the following resistance thermometers:
D NI100, NI500, NI1000
D PT100, PT500, PT1000.
resistance thermometers are connected via 4, 3 or 2-wire connections.
Byte assignment
The E ana occupies 4 input and 4 output bytes in the EI / EO address range of
the CL200.
Signal sources are connected via push-lock terminals.
The input module requires an external 24 V power supply.
