The job of the EL3152 analog input terminal is to supply power to measuring transducers located in the field and to transmit analog measurement signals with electrical isolation to the automation device. The voltage for the sensors is supplied to the terminals via the power contacts. The power contacts can optionally be supplied with operating voltage in the standard way or via a supply terminal (EL9xxx) with electrical isolation.
In the EL3154 with four inputs, the 24 V power contact is connected to the terminal in order to enable connection of 2-wire sensors without external supply. The power contacts are connected through.
The EL3161 analog input terminal processes signals in the range between 0 and 10 V. The voltage is digitized to a resolution of 16 bits, and is transmitted, electrically isolated, to the higher-level automation device.
The EL3162 analog input terminal processes signals in the range between 0 and 10 V. The voltage is digitized to a resolution of 16 bits, and is transmitted, electrically isolated, to the higher-level automation device.
The EL3164 analog input terminal processes signals in the range between 0 and 10 V. The voltage is digitized with a resolution of 16 bits and is transmitted (electrically isolated) to the higher-level automation device.
The EL3174 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. Physically, the voltage and current signals should be connected to different terminal points.
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.
The EL3174-0032 analog input terminal has four individually parameterizable inputs. Signals in the range from -3…+3 V or from -20/0/+4…+20 mA can be processed by each channel. Each channel should be set via the controller to U or I mode via CoE. The input voltage or current is digitized with a resolution of 16 bit, and is transmitted electrically isolated to the higher-level automation device.
The EL3174 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. Physically, the voltage and current signals should be connected to different terminal points. Each channel should then be set by the controller/TwinCAT to U or I mode via CoE. The voltage inputs operate differentially; the current inputs are single-ended.
The EL3182 analog input terminal for HART-capable field devices supplies measuring transducers located in the field and transmits their analog measuring signals electrically isolated to the automation device.
The EL3201 analog input terminal facilitates the direct connection of a resistance sensor. The measured resistance value can either be output directly in ohms or transformed into a temperature.
The EL3201-0010 is the high-precision version of the EL3201. The EL3201-0010 analog input terminal facilitates the direct connection of a resistance sensor.
