Series TH-02, Count - Down Digital Timers




SHIVA Controls & Systems' Model TH-02,series count down digital timers are based on CMOS technology to offer high performance models at an economical price with enhanced features. These timers have quartz crystal time base, for high repeat and time counting accuracy. These units have standard features including a 5Amp SPDT relay with user selectable Delay ON or Delay OFF control output logic. The required time is set on thumbwheel switches and the same is indicated on an easy-to-read LED display and an LED indication for output status. Timing inititiation is either by 'START' on power application or "START" on remote input pulse. Reset is automatic after elapse of the countdown cycle. These units have excellent noise rejection capability to work consistently under harsh and severe industrial environments.
