Line Seiki F90 Series Rate Indicators / Controllers
Product Made in Japan
Manufacturer: Line Seiki
Model: F90 Series
Description
The F90 Series is a panel-mounted Rate Indicator/Controller featuring a 6-digit red LED display with a digit size of 14.22×7.8mm, ensuring ease of reading even in dimly lit environments. This Controller type is fully programmable through the front panel keys, offering user-friendly customization.
The panel size is DIN 48×96, with a panel cut-out size measuring 45x92mm. The controller model provides three output types: Upper/Lower Limit output, Analog output, and BCD output.
Additional features include a Prescale function, multi-decimal point position adjustment, and a Key Lock function. The built-in memory ensures that the unit retains the last measured value, even in the event of an accidental power supply interruption.
