Introduction
2 channel resistance measurement terminal
The EL3692 analog input terminal allows direct resistance measurement in 9 measuring ranges from 0..100 MΩ to 0..10 mΩ on 2 channels.
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. It is possible to determine the connected resistance with an update rate up to 100 Hz.
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.
As further variants the EL3692-0020 with individual factory calibration certificate and the EL3692-0030 with external calibration certificate are available.
Please read the notes on the calibration certificate and identification features of these terminals.
