Beckhoff has released a new generation of analog I/O terminals in compact high-density housings. With up to eight channels and a 16-bit resolution, this new generation of analog terminals includes the EL4374, the first combined Beckhoff analog input/output terminal (10V/20mA or -20/0/+4 to +20mA) 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 same features are offered by the EL3072 and EL3074 analog input terminals, which now feature 16-bit resolution (previously 12-bit) as 10V/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.
