Beckhoff is significantly enhancing the performance of the EtherCAT Terminals with a new generation of analog I/O terminals in compact high-density (HD) housings. With up to eight channels and an impressive 16-bit resolution, the seven terminals cover a wide range of applications and deliver exceptional value.
The new generation of analog terminals includes the EL4374, the first combined Beckhoff analog input/output terminal (10 V / 20 mA or -20/0/+4 to +20 mA) compatible with a conversion rate of 2 ksps per channel. The two inputs and outputs can be individually parameterized for current or voltage operation via TwinCAT software and a CoE interface. With a technical measuring range of ±107% of the nominal range, the terminal supports commissioning with sensor values in the limit range and enables evaluation in accordance with NAMUR NE43. The outputs can provide up to 107% of the nominal value, and the high output power permits a load of up to 750 Ω at 20 mA.
The same features are offered by the EL3072 and EL3074 analog input terminals, which now feature 16-bit resolution (previously 12-bit) as 10 V / 20 mA universal inputs. The EL3072 is equipped with two individually parameterizable inputs, while the EL3074 has four. Another addition is the EL3078, which expands the lineup with eight channels in the same compact HD housing. These improvements - higher resolution and up to eight channels - are also available in the analog output terminals: EL4072, EL4074, and EL4078.
