The analog input module EP-3124 can record up to 4 analog sensors with ±10 V, ±5 V, 0-10
V, 0-5 V, 2-10 V, 1-5 V, 0-20 mA or 4-20 mA. The resolution is 12 bits per channel. Sensors
can be connected to each connector in a 2-wire, 3-wire or 3-wire connection + FE. The
measurement range is defined using parameterization. A status LED is assigned to each
channel. The module electronics supply the connected sensors with power from the input
current path (IIN).
The inputs are protected against voltage surges and overcurrent. Voltages that exceed ±30
V may cause the destruction of the module. As a protection against overcurrent, the module
temporarily switches to voltage mode.
