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.
