- Voltage Rating: 240 VAC
- Current Rating: 20 Amps
- Input Signal: DC Logic Voltage
- Firing Mode: Fast Cycle
- Output Device: Solid State Contactor / SCR Assembly
- Display: LED Bar Graph (0–20A), Fuse Fail & Input Indicators
- Mounting: Front Panel Mount
- Rear-mounted Ferraz 250V 25A Fuse
- Manufactured in the United States
Applications
Eurotherm 831 series controllers were used in industrial process heating, ovens, furnaces, and thermal management systems where proportional AC power control was required. These units integrate with PLC and automation systems via logic-level inputs. They are commonly found in semiconductor processing, materials testing equipment, and general industrial heating applications where precise temperature or power regulation is necessary.
This Eurotherm 831/20A240V/LVS-FC/M Digital Power Controller does not power on and is being sold as-is for parts or repair. It was tested at our facility and failed: the unit will not power up even with the large fuse bypassed, indicating an internal fault beyond the fuse. The rear terminal block shows some oxidation on the screw terminals, and the Ferraz 250V/25A fuse is present. No functionality is implied or guaranteed. Please view our photo set and contact us if you have any questions.
