5.2 Power Supply / 4 ... 20 mA-loop
The T32 is a temperature transmitter in 2-wire design. Depending on
the version, it can be supplied with different types of power supply.
Connect the plus pole of the power supply to the terminal marked
with j , the minus pole to the power supply marked with i. In the
case of flexible leads we recommend the use of crimped connector
sleeves.
The T32 temperature transmitter requires a minimum terminal
voltage of 12 V DC. The load must not be too high, because other-
wise the terminal voltage at the transmitter will be too low in the
case of relatively high currents.
The following diagram shows the maximum permissible load in
dependence on the supply voltage.
