Recommended tools for terminal screws:

Model Screwdriver Tightening torque

T32.1S Cross head (Pozidriv tip)

size 2 (ISO 8764)

T32.3S Slotted, 3 mm x 0.5 mm

(ISO 2380)

0.4 Nm

9.1 Power supply, 4 ... 20 mA current loop

The T32 is a 2-wire temperature transmitter. Depending on the

version, it can be supplied with various types of power supply.

Connect the positive line of the power supply to the terminal marked

with ⊕, the negative line of the power supply to the terminal marked

with ⊖.

With exible leads we recommend the use of crimped connector

sleeves. The integrated reverse polarity protection (wrong polarity on

the terminals ⊕ and ⊖) prevents the transmitter from damage. The

following maximum values are applicable:

■

Model T32.xS.000: DC 42 V

■

Model T32.xS.0IS: DC 30 V

■

Model T32.xS.0IC: DC 30 V

■

Model T32.xS.0NI: DC 40 V

The T32.xS temperature transmitter requires a minimum terminal

voltage of DC 10.5 V. The load must not be too high, as otherwise, in

the case of relatively high currents, the terminal voltage at the trans-

mitter will be too low.

The T32 is equipped with terminal voltage monitoring (“under-voltage”

detection).

If too small a voltage is detected at the terminal (< 10 V) the error is

signalled on the output (< 3.6 mA).
