MANUAL

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
