I'm wondering if anyone knows of a simple DIN rail mounted component that will take a 0 - 10vdc plc output and convert it to 0 - 15vdc signal. I need to drive a 100ohm proportional valve that is rated for 0-15vdc.

Thanks for the help OperaHouse. Simple and effective.

Thanks for the help. I'll be sure to bring it up the next time the dean of my college asks for my advice about whether or not the sequential logic course i did take should be offered using mechanical relays and not digital logic devices.

Does anyone know how to make a circuit using relays and momentary pushbuttons that will act as a silence feature for a buzzer. In other words I want a float to trigger a buzzer but allow a user to silence the buzzer by pushing a momentary pushbutton. I do not want the buzzer to reactivate until...

I've been a controls engineer for about 6 years now using PLC's like Allen Bradley and Semens to control temperature within a specific environment. In my effort to understand the internal workings better (and to become more fluent with my electronics) I’ve decided to build a simple digital...

I think i'm going to use an NTC thermistor to measure the iso thermal block. Or probably an easier method would be to use a digital temperature sensor since it is linear and i can wire it directly to the uProcessor

I've decided to make my own digital thermometer as a side project. I want to use a type K thermocouple as the sensing element. I'm using a PIC16F777 micro with an LCD output. I've got code (using picbasic pro) that will display the ADC to the LCD. I'm looking for information that will help me...

Thanks guys. I appreciate all your posts. I would like to use the micro except i'm using a PIC and i'm not that fluent in programming them (still learning) which is why i was looking for a hardware solution. I will probably just get the resistance tables from the manufacturer and try and program...

Range of -30 to 50 C is more than enough. I'm going to have a total of 6 probes but i can just mirror the circuitry for the rest. I found linear thermistors sold by omega and honeywell but they are expensive and from the schematics they only look like resistor networks. I found some circuits...

I need a linear circuit for a thermistor that has at least +/- 0.5 Deg C accuracy. Anyone tackle this before?
