Analog Input Module EP-3704 Connection Diagram EP-3704
The analog input module EP-3704 can detect up to 4 analog resistance thermometers. The resolution
is 16 bit 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.
