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 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!
