Comprehensive range of measurement I/O terminals

September 9th, 2014, Published in Articles: EngineerIT


High-end measurement applications and standard measurement technology tasks are capably covered thanks to a comprehensive range of measurement I/O terminals. The numerous analogue input terminals with standard resolution will suffice for many applications: for example, the KL30xx bus terminals as well as EL30xx EtherCAT terminals with 12-bit resolution record analogue signal voltages in a wide signal range from -2 to +2 V, -10 to +10 V, 0 to 2 V, 0 to 10 V, 0 to 500 mV, 0 to 20 mA and 4 to 20 mA. Standard EL31xx analogue input terminals with 16-bit resolution are already suitable for high-precision control processes. In addition, they also support time-critical applications thanks to the extremely fast A/D conversion time – ca 40 to 100 µs depending on the type – and provide support for EtherCAT distributed clocks.


High-end technology is further supported by terminals with 18 and 24-bit resolution and the corresponding measurement accuracy for standard current and voltage signals. In addition, highly accurate models are available for connecting thermocouples and resistance thermometers as well as versions for especially complex signals, such as performance measurement or condition monitoring based on IEPE acceleration sensors.
