Water heating cooling systems with external analogue setpoint ?

[thuaniam]

Dear all,

I need a water heating and cooling system to ramp up and ramp down temperature of a specimen. I have found that the Boe-therm Temp 95 can do the job (

http://www.fleming.net.au/files/brochures_for_web/boe-therm_brochures/brochure_temp_95.pdf).

However, I need to connect my control signal (as analogue 0 - 10V or in mA that is generated from my Labview software using NI hardware), to control the the temperature of the heating cooling system. Unfortunately, the Temp 95 does not have an external input for setting temperature (we have to press keys UP and DOWN to adjust temperature).

I may use the Temp 95 by making a board with relays that are controlled by Digital outputs from NI hardware to turn the relays of the Temp 95 board. However, this will cost much times for making the additional board and software. So, I would like to find another heating cooling control system that has external analogue setpoint.

Please let me have some options of water heating cooling control in similar with the Temp 95 but they have external analog input for setting temperature.


Thank in advance.

Van

You have a computer; why do you need or want to output analog? Why not just direct USB control?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

According to

http://www.boe-therm.com/Files/Billeder/Brochurer/ENG/Temp 95-ENG Brochure.pdf

0-10 volt, 4-20 mA, and many other external communication options are available as optional features.

Hi MintJulep,

Thank you. I will contact the provider for quoting a Temp95 with 0-10V interface option.
