Dual setting type temperature controller T4LP series can control heating and cooling at a time and realize high accuracy measurement of ±0.5% based on F•S value of each input. Also, it is dual setting type product that allows optimal low temperature controlling and high accuracy controlling. The series contributes to better user convenience by adopting digital switches.
Main features
● Dual setting type
● High accuracy measuring function: ±0.5%
● Control heater and cooler at once
● Use dual setting type of temperature when executing low temperature or precision control. In dual setting control type, the single output is operated as reverse, it is used for heater control. The dual output is used to control the operation of cooler normally. The dual output is also used for an alarm.
Specification Table
※F.S. is same with sensor measuring temperature range.
Ex) In case of using temperature is from 600 to 1600℃, Full scale is 1000.
※Environment resistance is rated at no freezing or condensation.
