Current inputs 0/..20 ma can be converted into voltage outputs, V can be converted to V, low mv inputs can be converted to standard outputs etc. Signal converter 61 accepts 2wire transmitters without separate power supply. Potentiometer input as a standard. Galvanic isolation is made at the same time with the convertion. Galvanic isolation cuts the noise signals which may exist when using low voltage signals, f.ex. thermocouples. selectable via DIPswitches: voltage 0.. V, V or current 0/. Converter 61 gives also the possibility to signal damping. There is four selectable dampings: 0,1 ms, 20 ms, 00 ms or 70 ms. Selecetion via DIPswitches. (Notice output rise times for high frequensies, page 8.) Operating voltage is also isolated from input and output. The common inputs and outputs are selected via DIPswitches. Fine adjustment is made with front panel zero and span potentiometers. 3

6 Range selections and output can be selected via DIPswitches. Table 1B contains ranges that can be selected without special actions (resistor changes etc.). Table marking SW stands for DIPswitchs postion ON or OFF. J2 is a short cut jumper, ON means that the pinns are short cutted (see table below). You can find switch and jumper locations from the component picture on this page. When selecting standard ranges, note the following jumper settings: J6 OFF, J7, J8 OFF.

7 Special range selections It is also possible to select inputs and outputs other than standard ranges, simply by DIPswitches. Special range selection is made via jumpers J2, J6, J7, J8 and different combinations of resistors R8, R32, R33, R3. Zero adjust and special dampings are also possible with those components. Table 2 contains part of special ranges and convertions. Other combinations are also possible, refer to manufacturer on this matter.

8 Potentiometer inputs: 61 can also be used as a position transmitter for potentiometers. Standard output ranges are in table 3 and special ranges in table. Potentiometer input is delivered to ordered potentiometer size, which can be changed later by selecting new range resistor R8. When modifying 61 to potentiometer, cut resistor R3 from the PCBboard. Also serial resistor R8 should be added, its size is depending to potentiometer size, see table. If the converter is already delivered to potentiometer, these modifications are made in factory. Select new size for R8 from table. If You have other potentiometer than in the table, serial resistor is 1, times greater than the potentiometer used. When selecting the output, notice the following jumper settings: J6 OFF, J7, J8 OFF. Also above mentioned R3 cutting. Other than standard output needs also R33 and R32 changes.
