Intended Use

The PolyTrans® P 32000 universal transmitters provide connection
facilities for all standard thermocouples, resistance transducers, strain
gauge full bridges, resistive sensors, and potentiometers.
When a resistive sensor is connected, 2-, 3-, or 4-wire confi guration is
automatically recognized at device startup.
The output signal is adjustable to 0 / 4 ... 20 mA, or 0 ... 5 / 10 V.
The calibrated range selection is performed using DIP and rotary
encoder switches. Alternatively, the devices can be confi gured via an
IrDA interface (located in the upper part of the unit) and the Paraly
SW 111 Windows software.
The device comes with 24 V DC power supply and galvanic 3-port
isolation.
The Models P 32000P0/1x can be part of a safety function according to
EN 61508, providing functional safety up to SIL 2 / SIL 3.
Prior to commissioning and after each change of the confi guration,
you must check the intended function of the transmitter (see Safety
Manual, section 5.1 "Functional Checks").
