Precise EtherCAT analog terminals with more channels
EtherCAT analog I/O terminals have enhanced their performance with compact high-density (HD) housings. With up to eight channels and 16-bit resolution, these seven terminals cover a range of applications.
They include EL4374, Beckhoff’s first, combined 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, this terminal supports commissioning with sensor values in the limit range, and enables evaluation in accordance with NAMUR NE43. Its 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.
These same features are offered by EL3072 and EL3074 analog input terminals, which now feature 16-bit resolution (previously 12-bit) as 10 V / 20 mA universal inputs. 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 EL4072, EL4074, and EL4078 analog output terminals.
