The temperature transducers of the IM12-

TI02… product series transmit temperature-dependent measured values in a galvanically isolated manner. The devices are suitable for operation in Zone 2 (ATEX region).

Thermocouples, low voltages, RTD sensors

and resistors can be connected to the devices

in the Ex area.

The temperature transducer IM12-

TI02-1TCURTDR-1I-0/24VDC features an

input for thermocouples in accordance with

IEC 60584, DIN 43710, GOST R 8.585-2001,

low voltages (-150…+150 mV), RTD sensors

in accordance with IEC 60751, DIN 43760,

GOST 6651-94 (2-, 3- or 4-wire) and 0…5-kò

resistors (2-, 3- or 4-wire). The current output

can be set to 0/4…20 mA and operated either

as source or sink.

Input and output circuits are monitored for

wire breaks. The device signals all detected

internal faults (e.g. an input value outside the

characteristic curve of the sensor) with a permanently red LED and the output of a fault

current.

The devices are configured via DIP and rotary

coding switches on the device side. The set

measuring mode (TC, RTD, low voltage, resistor) determines the selection options shown

for the other input parameters. The measuring

range is defined by setting a start value and

an end value within the measured value limits

of the connected sensor.

The devices each have one green and one

red power LED (Pwr) and one green and one

red channel LED (Ch…) for status indication.

The device signals all detected internal faults

(e.g. an input value outside the characteristic

curve of the sensor) with a permanently red

Ch… LED and—depending on the parameterization—with the output of a current signal

of 21 mA. In the event of a wire

break in the current output, the red Ch… LED

flashes twice repeatedly and the green Ch…

LED is constantly illuminated.

The device can be used in safety circuits up to

SIL 2 (high and low demand according to IEC

61508) (hardware fault tolerance HFT = 0).

The device is equipped with removable screw

terminals.
