Programmable converter PMR10

Temperature inputs from RTD or thermocouple sensors
Potentiometer or variable resistor inputs
Sensor supply for NPN, PNP, NAMUR and analogue inputs
Analogue or pulse outputs
Galvanic separation, supply - input - output
DC supply or AC supply voltages up to 400 VAC
Made in accordance with the
and EMC regulations
PMR10 is a multirange converter / isolation amplifier
with temperature, resistance, pulse and analogue inputs
and current, voltage, pulse or relay outputs.
The unit has a number of programmable input functions:
Temperature monitoring with 3-wire RTD sensors
Pt100, Pt500; Pt1000, Ni100, Ni500 and Ni1000, including sensor cable monitoring.
Temperature monitoring with thermocouple sensors
type J (Fe-CuNi), type K (NiCr-Ni), type R (Pt13%RhPt), type S (Pt10%Rh-Pt), type T (Cu-CuNi), type B
(Pt30%Rh-Pt6% Rh), type N (Nicrosil-Nisil) or type E
(NiCr-CuNi).
When the unit is programmed for thermocouple sensor,
you can select between internal Cold Junction Compensation and external CJC-box, which gives a higher accuracy.No matter which type of temperature sensor is used,
the unit will compensate for the unlinearity of the sensor.
Potentiometer monitoring. If this function is selected,
the output signal will indicate the actual position of the
potentiometer, independent of the total value of the potentiometer.
Resistor monitoring. With resistor monitoring the output
signal is an expression of the actual value of the resistor,
compared with the programmed metering range.
Speed monitoring with programmable inputs from NPN,
PNP or NAMUR sensors, including supply voltage for the
sensor.
Input signals from analogue transducers, including
supply voltage for the transducer.
You can select between 2 different output configurations:

• Type A is supplied with analogue current output, programmable between 0 and 20 mA and analogue voltage
output, programmable between -10 and +10 V.

If you want, you can order the unit with specified metering
ranges, or you can program it yourself, by means of the Cmac programming software for PC and a small interface to
connect between the PC and the module.
All parameters in the converter are programmable within
the specified limitations (min. and max. input and output
levels), giving the following possibilities:

• Basic converter, (0 to
defined input range and
standard output range,
0-20 mA, 4-20 mA or
0-10 V).

• Converter with input

e.g. 10 to 50 °C input
and 8 to 15 mA output.

it is also supplied with pulse output, programmable to a
maximum frequency of 10 kHz.
The unit is supplied with 2 trimming potentiometers,
which can be used to fine-adjust the metering range, if the
unit is used with analogue outputs. In either case the potentiometers can be disabled, if the adjustment possibility
is not wanted.
