The EL3174-0002 analog input terminal has four individually parameterizable inputs. Signals in the range from -10/0 to +10 V or -20/0/+4 to +20 mA can be processed via each channel. Each channel should be set by the controller to U or I mode via CoE.
he 2-channel analog input terminal EL3602-0002 is a variant of the EL3602 for measurements in the range ±200 mV. The voltage is digitized to a resolution of 24 bits, and is transmitted, electrically isolated, to the higher-level automation device.
The EL3751-0004 analog input terminal is a variant of the EL3751 multi-functional terminal that has been reduced to resistance or temperature measurement (RTD). The EL3751-0004 measures to 5 kΩ full scale value in 2-/3-/4-wire connection. RTD temperature sensors (Pt100/1000, NI, KTY etc.) can also be connected.
