Differential Analog Sensor Signal

Doug Coutlee 2 years ago updated 2 years ago 2

I am looking for a way to use a shunt style current sensor that has a differential analog output with an IQAN module. Does anyone have suggestions? https://riedon.com/resistors/view/ssa  Riedon-Smart-Current-Sensor.pdf

Powering down modules in runtime

NEricson 3 years ago updated by Gustav Widén (System support) 3 years ago 1

I have to modify my system and add 2 expansion (or masters if necessary) to meet safety standards. Only 1 module can be powered at a time. Is there a way to do so without having errors every time one is powered down?

Serial numbers from clone

Marcel 3 years ago updated 3 years ago 3

If you make a clone, can you read the serial numbers of the hardware where the clone is retracted from? In the clone file somewhere I mean.

Thanks,

Marcel

Is 5 - 7.5 uA correct for current consumption? or is that a typo in the data sheet?

4-20ma customer PLC supplied signal for monitoring (XC43)

mgoutier 4 years ago updated by Gustav Widén (System support) 4 years ago 2

I am designing a new system where the customer has to send me a 2 wire 4-20ma signal to monitor. I can add a resistor to convert it to a voltage input, but I would prefer not to. The manual shows a 3 wire hook up, if I were to not use the Vref pin, would this still work? I am not concerned about the output getting out of scale, and when we do a startup I can calibrate it to the PLC actual range... 

Should this work?

Industrial Style IQAN Module for Electrical Cabinet

Barnhart Crane 4 years ago updated 4 years ago 1

We've used IQAN modules extensively in our equipment and we've always mounted the modules in an electrical cabinet. We prefer the entire IQAN system to other PLCs that would normally be used in a cabinet, but we could really benefit from an IQAN module that was more industrial style, i.e. that it would have screw terminals that were easy to rearrange, add, remove, etc.

Has anything like this been considered before? Anyone else with this need?

PWM MR Values

BLC 4 years ago updated by Gustav Widén (System support) 4 years ago 2

I am trying to control a valve without over speeding the pump. What would the MR values need to be? Does 100% command at a 100% Max MR value equate to the source voltage, in this case 24VDC? See coil characteristics below.

Answer

If you have an important function like this you should not use PWM outputs from IQAN, you should use COUT. The PWM outputs from IQAN are not temperature compensated and you will see consistency / repeatability problems. When you use the current output channels with IQAN you will be able to set minimum and maximum current requirements easily and the current will compensate for changes in coil resistance.
