Temperature Controller, 1/16 DIN (48x48 mm), Terminal Block, Single Display, 4 Digit, PID Control, Relay and SSR Output, Alarm 1 Output + Alarm 2 Output , 100-240 VAC. Autonics TC Series PID Temperature Controllers - one of the most cost effective temperature controlling solution with essential functions and improved performance - realizes ideal temperature controlling with newly developed PID control algorithm and 100ms high speed sampling. Especially, that both SSRP output and relay output are supported to realize effective and economical controlling; in addition, improved visibility and compact size is another feature of TC Series.
