The job of the EL3151 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 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 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 EL3174-0032 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 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 EL3202-0010 is the high-precision version of the EL3202. The EL3202-0010 analog input terminal facilitates the direct connection of two resistance sensors. The measured resistance value can either be output directly in ohms or transformed into a temperature.
The EL3314-0030 analog input terminal allows four thermocouples to be connected directly. The circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable.
The EL3318 analog input terminal allows eight thermocouples to be connected directly and is thus particularly suitable for space-saving use in control cabinets. The EtherCAT Terminal circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable.
The analog EL3356-0020 input terminal enables direct connection of a resistor bridge or load cell in a 4- or 6-wire connection technology. The ratio between the bridge voltage UD and the supply voltage UREF is determined simultaneously in the input circuit and the final load value is calculated as a process value on the basis of the settings in the terminal.
The analog EL3356-0090 input terminal enables direct connection of a resistor bridge or load cell in a 4- or 6-wire connection technology. The ratio between the bridge voltage UD and the supply voltage UREF is determined simultaneously in the input circuit and the final load value is calculated as a process value on the basis of the settings in the terminal. With automatic self-calibration (can be deactivated) and dynamic filters the terminal with measuring cycles of 10 ms can be used for slow weighings with high precision.
