Programmable converter type PMR10
Programmable converter type PMR10
| 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%Rh-Pt), 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. Type B has the same outputs as type A, but in addition 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, or to adjust the set-point if the unit has relay outputs. In either case the potentiometers can be disabled, if the adjustment possibility is not wanted. |
If you want, you can order the
unit with specified metering ranges, or you can program it yourself, by means of the C-mac
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 and/or output offset, e.g. 10 to 50 °C input and 8 to 15 mA output. |  |
||
| Bidirectional output range (only voltage output), e.g. -10 to +10 V. |  |
||
| Inverted function with or without offset, e.g. 150 to 20 Ohms input and 4 to 20 mA output. |  |
