Atmosphere / Temperature Controllers

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.

• 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 wtih SSi's eSPP
