The EL3602 analog input terminal handles signals in the ranges ±10 V, ±5 V, ±2.5 V and ±1.25 V. The voltage is digitised to a resolution of 24 bits, and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal have differential inputs and possess a common, internal ground potential. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.

The EL3403 EtherCAT Terminal enables the measurement of all relevant electrical data of the supply network. The voltage is measured via the direct connection of L1, L2, L3 and N. The current of the three phases L1, L2 and L3 is fed via simple current transformers. All measured currents and voltages are available as root-mean-square values. In the EL3403 version, the effective power and the energy consumption for each phase are calculated. The root-mean-square value of voltage U, current I and the effective power P, apparent power S, reactive power Q, frequency F and phase shift angle cos φ can be derived. The EL3403 provides a comprehensive network analysis and an energy management option.

The EL3356 analog input terminal permits direct connection of a resistance bridge. The ratio between the bridge voltage UD and the supply voltage UREF is determined in the input circuit. In order to achieve good long-term stability, the complete circuit is re-calibrated at least every 3 minutes. This procedure can be synchronised by the control in order to prevent the calibration leading to a delay in the production process.

The EL3351 analog input terminal permits direct connection of a resistor bridge. The bridge voltage, UD, and the supply voltage, UREF, to the bridge are digitised with a 16 bit resolution, and are transmitted along an electrically isolated channel to the supervising automation system. The input channels are available in the form of two 16 bit values for further processing. The resulting measurement can be calculated from the formula: measurement = UD/UREF. Precise acquisition of the supply voltage along with the bridge voltage compensates for long-term and temperature drift.

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 linearisation across the whole temperature range, which is freely selectable. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal temperature measurement at the terminal. The EL3318 can also be used for mV measurement.

The EL3314 analog input terminal allows four thermocouples to be connected directly. The EtherCAT Terminal circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal temperature measurement at the terminal. The EL3314 can also be used for mV measurement.

The EL3311 and EL3312 analog input terminals allow thermocouples to be connected directly. The EtherCAT Terminals circuit can operate thermocouple sensors using the 2-wire technique. Linearisation over the full temperature range is realised with the aid of a microprocessor. The temperature range can be selected freely. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal temperature measurement at the terminals. The EL3311/EL3312 can also be used for mV measurement.

The EL3255 EtherCAT Terminal enables potentiometers to be connected directly. A stabilised power supply in the terminal and the ratiometric measurement of the input voltage offer the preconditions for precise measurement. On account of its high sampling rate and together with potentiometer position encoders, the compact 5-channel EtherCAT terminal represents an economical position detector.

The EL3204 analog input terminal allows resistance sensors to be connected directly. The EtherCAT Terminal circuit can operate sensors using the 2-wire technique. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The EtherCAT Terminal’s standard settings are: resolution 0.1 °C in the temperature range of PT100 sensors. Sensor malfunctions such as broken wires are indicated by error LEDs.

The EL3202 analog input terminal allows resistance sensors to be connected directly. The EtherCAT Terminal circuitry can operate 2- and 3-wire sensors. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The EtherCAT Terminal’s standard settings are: resolution 0.1 °C in the temperature range of PT100 sensors in 3-wire connection. The EtherCAT Terminals indicate their signal state by means of light emitting diodes. Sensor malfunctions such as broken wires are indicated by error LEDs.
