EtherCAT I/O Products, Analog Input, Current, Voltage

EtherCAT I/O Products process the most typical standard signals encountered in the automation industry, such as 0 to 10 V, ±10 V, 0 to 20 mA and 4 to 20 mA, are supported and pre-processed along with other measured variables such as resistance, pressure or temperature. The product portfolio additionally includes analog EtherCAT Terminals for the connection and evaluation of special sensors such as strain gauges, thermocouples, resistance thermometers and accelerometers. Special analog EtherCAT Terminals are also available for measurement tasks in energy and power measurement.

Due to a comprehensive selection of terminals with different numbers of channels, resolutions and measuring accuracies, the right product is available for every application, from simple industrial applications to high-precision measurement technology.

Advantages:

• robust measurement of analog signals with long-term availability
• fine scalability of channel density and functional scope
• extensive adjustment and diagnostic options in the terminals via the EtherCAT bus
• distributed clocks for the precise acquisition of the timestamp of an input signal and synchronization of the network
• optionally calibrated terminals for precise acquisition of the measurement uncertainty

Several EtherCAT I/O Products are offered with a factory calibration or external calibration certificate (ISO17025 or DAkkS).

Integration of standard signals in safety applications: The TwinSAFE SC (Single Channel) technology enables the use of standard signals for safety tasks in any networks of fieldbuses. To do this, EtherCAT Terminals from the areas of analog input, angle/displacement measurement or communication are extended by the TwinSAFE SC function. The typical signal characteristics and standard functionalities of the I/O components are retained. TwinSAFE SC I/Os are distinguished from standard I/Os by a yellow strip on the front of the housing and the product name extension -009x.
