PID Temperature Controller - BC-9090

171Favourite PID controller for the New Zealand industry for more than a decade.

One of the most popular 48x48 controllers over the last ten years!

The Brainchild BTC9090 has been sold by us in New Zealand for more than ten years and there are many in operation.  While the series has been updated by the BTC 9100, many users prefer the more simple menu system of the 9090 and do not need the option of a digital interface.

  • Universal Input, T/C, RTD* and voltage
  • Relay, Logic for SSR, or continuous [4-20mA] output
  • One alarm relay standard
  • Auto tune PID with fuzzy logic
  • Low voltage version for supplies down to 20VDC [for 12VDC use BC-9100]
  • Plug in from front [interchangeable] case only 90mm deep
  • Dual Display
* Note that for RTD inputs, a solder link C3 has to be modified on the main PCB near the ambient temperature compensator.

The 9090 can be converted at our workshops from one version to another so that availability is assured.
