Download the Datasheet

The AC20 controller is designed to control both endothermic generators and atmosphere furnaces. To accomplish both, the AC20 can display and control on three units of measure: % Carbon, Dew Point or probe millivolts. In addition, Probe resistance, probe temperature, COF, H2F and probe recovery can be displayed.

Features:

  • Simple to configure, simple to operate
  • Designed specifically for atmosphere control
  • Functions well on batch or continuous furnaces and endothermic generators
  • 1/4 DIN, % Carbon, Dew Point, O2 Millivolts
  • Internal timers for burn-out / probe maintenance
  • On-board probe diagnostics
  • Events: 8 IN - 10 OUT
  • RS485, Modbus Communication protocol
  • Ships pre-configured per your specifications
  • Programmable when interfaced with SSi's eSPP
