The
Model SK632 is a microprocessor PID programmable controller that accepts any
combination pH or ORP electrode as an input. Outputs are; ( one or
two ) on-off or proportional control relays ( these controls can be
SSR drive or mechanical contacts), one relay controls above the set
point and one controls below the set point; a 4 to 20 mA recorder
signal proportional to the pH or ORP level (0 to 14pH or
+1000to-1000mv) is standard.
Optional outputs are:
isolated, single or dual proportional pulse outputs designed to
drive proportional pumps with a 0 to 120 pulse per minute frequency
output; or single or dual isolated 4 to 20 mA proportional outputs
to drive pumps that require a 4 to 20 mA drive.
Optional dual
programmable alarms can be added to alarm high, low, zone, with
absolute or deviation set points. Optional input to output Isolated
4 to 20 mA output is available, as a recorder or remote signal, 4 mA
at 0 pH and 20 mA at 14 pH Optional 24 v ac/dc power
is available.
The power source is
from 85 to 265 VAC, 50/ 60Hz free voltage there is no need to change
connections for different voltages.
The front panel is NEMA 4X rated and
mounting hardware is provided. CRU, RU&CE approvals are standard
