DIGITAL INDICATING CONTROLLER LT110 SERIES LT110 series, 1/32 DIN size, miniature digital indicating controllers, feature all functions that are convenient in various control applications. The controllers are applicable to various equipment including semiconductor manufacturing equipment, electronic parts manufacturing equipment, food-processing machinery, packaging machinery, injection machine. FEATURES Small size, lightweight, short space Universal input consisted of 5 kinds of T/C input and 4 kinds of RTD input, and multi-input of 5 kinds of T/C input Optimum PID values are automatically calculated for accurate and stable control by PID auto-tuning. Various functions including sensor correction, setpoint lock, setpoint limit, control output OFF, and alarm action delay timer are built-in. The controllers conform to CE and the front panel is dust-proof and water-proof conforming to IP-65.
