EL3692 | EtherCAT Terminal, 2-channel analog input, resistance, 100 mΩ…10 MΩ, 24 bit
EL3692 | EtherCAT Terminal, 2-channel analog input, resistance, 100 mΩ…10 MΩ, 24 bit
SPS IPC Drives 2018:
Measurement technology with Bus Terminals: Functional overview and parameterisation
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The analog EL3692 input terminal enables direct resistance measurement in nine measuringe ranges from 0…100 mΩ to 0…10 MΩ. The circuitry of the EtherCAT Terminal enables measurement in 2- and 4-wire versions. The EL3692 offers measuring range selection, either automatic or through the controller. Due to the galvanic isolation of 1500 V between the field side and the E-bus, in single-channel mode measurements can be carried out at live points (within the permissible range). The EtherCAT Terminal indicates its state through LEDs. Malfunctions such as broken wires are indicated by error LEDs.
