EL3068 | Beckhoff Terminal, 8-Channel Analog Input

BECKHOFF · HMIs & Displays

Description  The EL3068 EtherCAT Terminal features eight channels for processing voltage signals within the 0 to 10 V range. Each channel digitizes voltage inputs with a resolution of 12 bits and transmits them in an electrically isolated manner to the higher-level automation system. This terminal consolidates all eight channels into a single housing, with power contacts routed accordingly. The 0 V power contact serves as the reference ground connection for all inputs, ensuring consistent signal integrity.     Technical Specifications  Part Number EL3068   Category   PLCs / Machine Control   Subcategory   PLC Programming Terminal   Number of inputs   8 ( single-ended )   Power supply   via the E- bus   Signal voltage   0…10 V   Distributed clocks   –   Internal resistance   > 130 kΩ   Input filter limit frequency   1 kHz   Dielectric strength   max . 30 V   Conversion time   1.25 ms default setting , configurable , multiplex   Resolution   12 bit (16 bit presentation incl . sign )   Measurement error / uncertainty   < ±0.3% ( relative to full scale value )   Electrical isolation   500 V (E- bus / signal voltage )   Current consumption E- bus   typ . 130 mA   Bit width in the process image   inputs : 32 byte   Special features   activatable FIR/IIR filters , limit value monitoring   Operating / storage temperature   -25…+60°C/-40…+85°C   Weight   approx . 60 g   Relative humidity   95%, no condensation   Vibration / shock resistance   conforms to EN 60068-2-6/EN 60068-2-27   EMC immunity / emission   conforms to EN 61000-6-2/EN 61000-6-4   Protect . rating / installation pos .   IP20/ variable       Information About EL3068 The EL3068 EtherCAT Terminal is designed for processing analog signals within a voltage range of 0 to 10 V.
