The EL3021 analog input terminal processes signals in the range between 4 and 20 mA. The current is digitized to a resolution of 12 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 EL3021 is the single-channel version and is characterized by its fine granularity and electrical isolation.
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 EL5021 EtherCAT Terminal is used for the direct connection of a measuring probe or encoder with sinusoidal, differential voltage output 1 VPP. Input frequencies of max. 250 kHz can be evaluated.
The EL5021-0090 EtherCAT Terminal is used for the direct connection of a measuring probe or encoder with sinusoidal, differential voltage output 1 VPP. Input frequencies of max. 250 kHz can be evaluated. The current counter reading can be zeroed (reset) or stored separately via the C track of the encoder, which is also called reference mark.
The EL6021 serial interface enables the connection of devices with RS422 or RS485 interface. These devices communicate with the automation device via the coupler.
The EL6021-0021 serial interface enables the connection of devices with RS422 or RS485 interface. These devices communicate with the automation device via the coupler.
The KL3021 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitized to a resolution of 12 bits and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3351 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 KL4021 analog output terminal generates analog output signals in the range from 4 to 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The KL6021 serial interface allows devices with an RS422 or RS485 interface to be connected. The device connected to the terminal communicates with the automation device via the Bus Coupler.
