Electrical connection
9.1
Operating voltage range
This transmitter is a loop-fed, 2-wire, low-voltage DC device. Like all devices with a 2-wire design, the transmitter is supplied directly from
the current loop and enters a current proportional to the measuring size from 4…20mA .
The operating voltage of the device is 12...30 VDC. The transmitter must under NO circumstances be operated
with ANY other supply voltage. Too low a voltage can result in malfunctions; too great a voltage can cause
irreparable damage to the device.
Ensure the correct polarity when making the electrical connection. Inverted polarity means that the device does
not work. The transmitter will not be damaged, as its connection terminals are secured against voltage reversal.
