Introduction

Fig. 8: EL3692
2 channel resistance measurement terminal
The analog EL3692 input terminal enables direct resistance measurement in a wide range between 10 mΩ
and 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. 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.

Technology

The EL3692 resistance measuring terminal can measure resistances between 10 milliohm (mΩ) and 10
megohm (MΩ). 2- and 4-wire measurements are supported. The terminal is fully configurable via the Bus
Coupler or the control system. Different output formats may be selected or own scaling activated.
