Heat controllers

today, my employer received a head controller we needed so that
we can update an oven system that uses steam as it's heat source.
this system uses a IP 4..20 ma control.. So had to rush in
a heat controller that supported the 4..20 output...

This damn thing came from Korea! "Hanyoung" Any one ever
use their electronics? are they any good ?

I must say, It has all the inputs and outputs ever needed for
any configuration with a basic model number except if you need
a RS-485 version which is just the next model up.
THis thing comes equipped with Relay out in Heat and cool and
you can have SSR out for heat or cool or Logic out for Heat and cool
or what they call retransmission of 4..20 ma from the logic terminals
and it has all types of thermocouple inputs including a 4..20ma input
all programmable ..
Its kind of hard to find a single heat/cool control that has all of
that. You normally would need to specify the Hardware options in your
order code.

 

Have you tuned the PID controller, yet?

 

Not too sure. I remember using hangyung units with success but that was a
while ago.
