Overview
The Athena 2000-T-0-0-08F-000 is a 1/4 DIN panel-mounted analog temperature controller engineered for precise proportional control across HVAC, refrigeration, and industrial heating applications. With a 0-800°F sensor range and single-pole double-throw relay output rated at 2A, this controller delivers reliable on-off or proportional temperature management with 50/60Hz input compatibility. The metal-case enclosed design ensures durability in demanding environments while maintaining compact footprint efficiency.
Key Features
- 1/4 DIN panel mount form factor for standard control enclosures
- Thermocouple or RTD input with sensor break protection
- Adjustable control mode from hysteresis to proportional band (5–25°F range)
- Dual meter dial display for visual process and setpoint indication
- 120/240 Vac single-phase control power input
- 2A SPDT relay output for heating/cooling load switching
