REX-P300
The REX-P300 is a program controller which stores a maximum of 256 segments in 16 patterns, 16 segments per pattern.
  • 5-digit display
  • High accuracy of ( 0.1% of reading or 1°C[°F] whichever is larger ) ± 1 digit.
  • Time signal which can output 4 or 8 digital output points up to 16 times / pattern.
  • Control in three modes, that is program mode, FIX mode and manual mode.
