Module EP 3704

The analog input module EP-3704 can detect up to 4 analog resistance thermometers. The

resolution is 16 bits per channel. A sensor can be connected to each connector in a 2-wire,

3-wire or 4-wire connection. Mixed operation using different sensors as well as different

connection methods is possible. Sensor type and temperature range are set using

parameterization. A status LED is assigned to each channel.

The inputs are protected against voltage surges and overcurrent. Voltages that exceed ±30

V may cause the destruction of the module.

The module provides individual channel diagnosis with channel related error messages.
