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 EL3351 analog input terminal permits direct connection of a resistor bridge. The bridge voltage, UD, and the supply voltage, UREF, to the bridge are digitized with a 16 bit resolution, and are transmitted along an electrically isolated channel to the supervising automation system.
The analog EL3356 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.
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 analog EL3692 input terminal enables direct resistance measurement in nine measuringe ranges from 0…100 mΩ to 0…10 MΩ. The circuitry of the EtherCAT Terminal enables measurement in 2- and 4-wire versions.
The EL4011 analog output terminal generates analog output signals in the range between 0 and 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The EL4012 analog output terminal generates analog output signals in the range between 0 and 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The EL4021 analog output terminal generates signals in the range between 4 and 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The EL5001 EtherCAT Terminal is an SSI master and enables the direct connection of an absolute encoder with SSI (synchronous serial interface). Both singleturn and multiturn encoders are supported. The 24 V supply of the encoder can be provided directly via the terminal connection points. The EL9505 power supply unit terminal can be used for an optional 5 V encoder operating voltage.
The EL5001-0011 SSI monitor EtherCAT Terminal is used for monitoring the data exchange between SSI master and SSI encoder (slave). The encoder is powered via the existing SSI interface. The interface circuit makes the incoming data stream available to the controller as a data word in the process image. Various operating modes can be permanently set via the control register.
