Load resistance
490 / 440 ohms, pulsing (cyclic interrogation of the I/O points)
Note: if the peripheral device can not drive this load, the signal must be
connected via a current measuring converter.
Open connection can be detected. Supports 0…20 mA input range, with signal voltages >10 V. Use AI type U10
instead with an external resistor.
