The UR20-4AI-UI-16-HD 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 con-
nector in a 2-wire, 3-wire or 3-wire connection + FE (IDC).
The measurement range is dened using parameterisation.
A status LED is assigned to each channel. The module elec-
tronics supply the connected sensors with power from the
input current path (I
IN
).
Each sensor output is loadable with 500mA and protected
agains overcurrent. 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.
