EJ3202 - Introduction

2-channel analog input Pt100 (TRD), 2- or 3-wire connection

The analog input module EJ3202 allows the direct connection of resistance sensors. The circuit of the EJ3202 can operate sensors in 2- and 3-wire technology. Several characteristic sensor curves (Pt100, Pt1000, NI120, NI1000, KTY types and others) are supported.

The module can measure the temperature at the measuring point or output the resistance value of the sensors directly. For temperature measurement, the temperature value is calculated using the characteristic curves stored in the module.

The default setting of the EJ3202 is: Resolution 0.1 °C in the temperature range of Pt100 sensors in 3-wire connection.

The EtherCAT module indicates its signal state by LEDs. The error LEDs indicate sensor faults (e.g. a broken wire).
