AUTONICS T3HA-B3RP0C is a thumbwheel switch digital temperature controller from the T3HA series. It offers simple mechanical setpoint adjustment with reliable ON/OFF or proportional control. It is designed for industrial applications requiring basic temperature regulation like ovens, heaters, and process lines.
Features
- Thumbwheel switch for easy manual setpoint setting without programming keys
- Selectable ON/OFF or P control modes for stable temperature maintenance
- Relay output for direct load switching, plus alarm output for monitoring
- Built-in hysteresis and proportional band adjustment for fine control
- Proportional cycle fixed at 20 sec for consistent operation
- Compact DIN W48 × H96 mm size for panel mounting in harsh environments
