A new generation of Beckhoff analog I/Os

Multi-functional and powerful with 16 bits and up to 8 channels for all standard signals between ±10 V and ±20 mA.

The EL3072 and EL3074 analog input terminals are the 10 V/20 mA universal inputs of the 12-bit class. The EL3072 has two single parameterizable inputs. Signals either in the range -10/0…+10 V or in the range -20/0/+4…+20 mA can be processed by each channel. Physically, the voltage and current signals should be connected to different terminal points. Each channel should then be set by the controller/TwinCAT to U or I mode via CoE. The voltage and current inputs are single-ended, which means that one connection point of each channel is connected in the terminal to +24 V or GND. All inputs are digitized with a resolution of 12 bits and transmitted electrically isolated to the higher-level automation device. With a technical measuring range of ±107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43.

The EL3072 and EL3074 analog input terminals are the 10 V/20 mA universal inputs of the 12-bit class. The EL3074 has four single parameterizable inputs. Signals either in the range -10/0…+10 V or in the range -20/0/+4…+20 mA can be processed by each channel. Physically, the voltage and current signals should be connected to different terminal points.

The EL3072, EL3074, and EL3078 analog input terminals record 10 V / 20 mA standard signals with 16-bit resolution and up to 2000 measured values per second. Each channel can be parameterized individually via the controller/TwinCAT; signals in the range of -10…+10 V, 0…+10 V, -20…+20 mA, 0…+20 mA, and 4…+20 mA can be processed by each channel. In terms of electrics, the voltage and current signals must be connected to different terminal points. The voltage and current inputs are single-ended, which means that one connection point of each channel is already connected in the terminal to +24 V or GND and no longer needs to be wired separately. With a technical measuring range of ±107% of the nominal range, the terminals also support commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43.

The EL4374 analog input terminal combines two analog inputs and two analog outputs that can be individually parameterized by the controller/TwinCAT via CoE for current or voltage operation. Depending on the setting, the channels process signals with 2 ksps in the range of -10/0 to +10 V or -20/0/+4 to +20 mA.

The EL4072, EL4074, and EL4078 analog output terminals output 10 V/20 mA standard signals with 16-bit resolution and up to 2000 values per second. Each channel can be parameterized individually via the controller/TwinCAT. All known standard signals in the range of ±10 V and ±20 mA can be output per channel – for example, 4…20 mA. The current outputs can also drive high burden resistors and report an overload or wire break or, in the case of a voltage output, a short circuit. The voltage and current outputs are designed as single-ended, which means that one connection point of each channel is already connected in the terminal to +24 V or GND and no longer needs to be wired separately. The EL4072 and EL4074 have 24 V/0 V contacts for the supply of the actuators. With a technical output range of ±107% of the nominal range, the channels can even transport unconventional setpoints, such as for error reporting purposes.
