Measuring transducers, calibrateable, with active output
SUPPLY VOLTAGE :
For operating voltage reverse polarity protection, a one-way rectifier or
reverse polarity protection diode is integrated in this device variant.
This internal one-way rectifier also allows operating 0 - 10 V devices on AC
supply voltage.
The output signal is to be tapped by a measuring instrument. Output
voltage is measured her against zero potential (O V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage
input UB+ is to be used for 15...36 V DC supply and UB – or GND for ground
wire!
When several devices are supplied by one 24 V AC voltage supply, it is to
be ensured that all "positive" operating voltage input terminals (+) of the
field devices are connected with each other and all "negative" operating
voltage input terminals (–) (= reference potential) are connected together
(in-phase connection of field devices). All outputs of field devices must be
referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage short-
circuit would be caused by that device. The consequential short-circuit
current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!

TEMPERATURE RANGES:

When selecting measuring transducer ranges,
it is necessary to ensure that the maximum temperatures
permissible for sensor ⁄ enclosure are not exceeded !
Ambient temperature for measuring transducers:
– 40 ...+ 85 °C
