RKC INSTRUMENT PF900 ramp soak ¼ DIN process controller stores up to 1024 segments (99 patterns with 10 segments of 10 segments of up to 99 patterns). A new RSS (ramp soak stabilizer) algorithm suppresses overshoot at the transition time from ramp to soak. Select from a sampling speed of 0.05 sec. for better control resolution or 1/0.25 a sampling speed to stabilize in applications requiring higher resolutions. The 11 character display shows the memory group number and set value, wait zone set value, remaining time, output values, running pattern segment and a program pattern/output bar gragh. Versatile event handling is accomplished with as many as 11 digital inputs and 12 digital ouputs.
