The 2-, 4-, 6- or 8-channel ELM314x EtherCAT Terminals in the Economy line can be set to current or voltage measurement channel by channel, offering sampling rates of up to 1 ksps per channel. Analog signals in the ranges from ±1.25 to ±10 V, 0 to 10 V, ±20 mA or 0/4 to 20 mA can be processed. The settings for U or I measurement mode and the desired measuring ranges can be selected via the control system and TwinCAT in the CoE interface. Here it is also possible to select the extensive diagnostics features for unattended long-term use. The 2-, 4- or 6-pin push-in connectors can be removed for maintenance purposes; they enable a direct supply of connected sensors. The power contacts on the side simplify the potential distribution directly on the DIN rail. The typical EtherCAT features are available: distributed clocks functionality with timestamp and the familiar data features of the basic line such as filtering, true RMS calculation and more.

The EtherCAT Terminals from the ELM series were developed in order to enable the high-quality measurement of common electrical signals in the industrial environment. Flexibly usable measurement modules are especially useful in laboratory and testing technology environments. Therefore the ELM370x multi-function modules feature an input circuit that can be set to over 30 different types of electrical connection via EtherCAT: from voltages of ±60 V to ±20 mV, thus supporting thermocouples and IEPE, a current of ±20 mA, a resistance measurement of 5 kΩ and thus also temperature RTDs (Pt100, etc.), measuring bridges and potentiometers, and all of this with a 2- to 6-wire connection, depending on the type. Thus, most electrical measuring tasks can be solved with just a single module. There is a choice of different connection types: The ELM3704-0001 with its high-quality LEMO connectors is mainly designed for laboratory use, where sensor configurations are changed on a daily basis, but a stable and reliable plug connection is nevertheless required. The 6-pin version with push-in (ELM3704-0000/ELM3702-0000) on the other hand is ideal for industrial use where a plug is unplugged less frequently for maintenance purposes and fast wiring is much more important.

The ELM3542 and ELM3544 EtherCAT Terminals from the ELM3x4x economy series are designed for the evaluation of measuring bridges in full bridge, half bridge and quarter bridge configuration. With a maximum data rate of 1 ksps per channel they are ideally suited for the recording of less dynamic procedures, such as slow oscillations and corresponding weighing procedures. In return, they measure with extremely low noise and are temperature-stable up to an ambient temperature of 60°C. The integrated bridge supply can supply 1 to 12 V and, like all other parameters, is adjustable online in the CoE at runtime. In addition, the ELM3542 features a connection for one TEDS-IC in the sensor per channel – this way the SG can be electronically read, detected and also written immediately upon plugging in. Apart from that, the ELM354x have all the features familiar from the fast ELM350x basic series, such as internally switchable extension resistors and comprehensive sensor and function diagnostics for industrial 24/7 operation. The 6-pin connector (push-in) is removable for maintenance purposes without releasing the individual wires.

With the ELM2742 Beckhoff is considerably extending the usage possibilities of the integrated measurement technology of the ELM3xxx series as well as the normal EL3xxx/EL4xxx analog inputs and outputs, because several sensors or sources can now be connected at the same time to one analog input channel. To this end, the ELM2742 is equipped with non-wearing solid-state relays (semiconductor switches) as switching elements, which are specially designed for small analog signals and thus set themselves apart from normal solid-state terminals like the EL279x. Due to the extremely low leakage current in the nA range in the opened state, the parallel-connected signals hardly influence each other at all. The multi-channel recording of analog signals as well as the flexible switching of various test states in production-integrated test stations is thus simple to achieve without externally connected switches.

The EKM1101 EtherCAT Coupler connects the ELMxxxx EtherCAT measurement modules with EtherCAT. Such a station consists of an EKM1101 coupler, any number of EtherCAT Terminals and a bus end cap or an EtherCAT extension such as EK1110 or EK1122. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation.

The ELM9410 power supply terminal is used to increase the E-bus current. The exchange of data between EtherCAT Couplers and the connected EtherCAT Terminals takes place over the E-bus. Each EtherCAT Terminal requires a certain amount of current from the E-bus (see technical data at the respective terminal: “Current consumption E-bus“). This current is fed into the E-bus by the power supply unit of the respective EtherCAT Coupler. In configurations with a large number of EtherCAT Terminals, the ELM9410 can be used to increase the current supply to the E-bus by 2 A.

Each assembly must be terminated at the right hand end with bus end cover. The ELM9012 also covers the power contacts in addition to the E-bus and is color-matched to the ELM terminal series.
