The UR20-4AI-UI-16 analogue input module can record up
to 4analogue 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 16bit per channel. Sensors can be connected to each
connector in a 2-wire, 3-wire or 3-wire connection + FE. The
measurement range is dened using parameterisation. A sta-
tus LED is assigned to each channel. The module electronics
supply the connected sensors with power from the input cur-
rent path (I
IN
).
The inputs are protected against voltage surges and overcur-
rent. Voltages that exceed ±30V may cause the destruction
of the module. As a protection against overcurrent, the mod-
ule temporarily switches to voltage mode.
