Beckhoff EL3318 original analog input terminal

The EL3318 is an eight-channel analog input terminal from the Beckhoff EtherCAT Terminal series, designed for direct connection of thermocouples. Each channel independently measures the low-level thermoelectric voltage, performs cold-junction compensation, and delivers a linearized temperature value to the controller over EtherCAT. With eight channels in a compact housing, it is the high-density choice for multi-point temperature acquisition in machine building, process automation, and test stands.
