functional overview
General
Analogue Input AE/S 4.2 is a DIN rail mounted device for integration into
the distribution board. The connection to the bus is established via a bus
connection terminal at the front of the device. The physical address is
assigned, and the parameters are set, using ETS 2, Version V1.3 or higher.
The device enables you to record and process four independent analogue
input signals in accordance with DIN IEC 60381 (0 – 1 V, 0 – 5 V, 0 – 10 V,
1 – 10 V, 0 – 20 mA, 4 – 20 mA, 0 – 1000 ohm, PT100 in 2-conductor
technology – 30...+ 70 °C, PT100 in 2-conductor technology – 200...+ 800 °C
and floating contact interrogation).
All conventional sensors can be connected.
The device has an integrated power supply unit to supply the sensors with
24 V DC voltage. The mains voltage is 115...230 V AC (+ 10% – 15%
tolerance), 50/60 Hz.
A constant output current of at most 300 mA is made available across the
entire input voltage range (115...230 V AC).
The input signals are processed in the
Threshold value measurement/1
application program.
The sensor output signals can be freely set for each channel in the
application program. The measured value can be sent as a 1-bit value,
1-byte value, 2-byte value or 4-byte value via the bus.
Due to the flexible setting options for the measuring range, depending on
the transfer of the measured value, all the possibilities for depicting the
expected measurement curve are possible. The sensor measurement curve
can be corrected or adjusted, depending on the setting. This flexibility
enables only a specific range of the expected measurement curve to be
evaluated.
Measured values can be averaged over 4, 16 or 64 measurements.
One measurement is taken every second.
It is possible to set 2 threshold values per channel, each with an upper and
lower limit which can be set independently. The threshold values themselves
can be modified via the bus.
It is possible to compare 2 output values, add them, subtract them or
calculate the arithmetic mean.
To guarantee all the programmable functions, the technical data
of the sensor manufacturer must be observed.
