The MC9300/9500 Series Controllers are a microprocessor based controller of recirculating cooling water systems. The controllers provide the ability to accurately control the level of dissolved solids based on µS/cm, and depending on model selection, control conductivity, pH, ORP and cycles of concentration based on the conductivity of the system make-up water.

The controllers feature:

• Up to four user selectable timers that will operate in any one of seven modes.
• A manually entered data collection field with ten user defined fields and units, stored in the controller's history (downloadable with PULSAworks software).
• Four single-point drum level inputs (9500 only)
• Multiple security levels and lockable input window.
• One or two point calibration
• Ability to reset relay "ON" times with date/time stamp
• Calibration date/time stamp
• Two water meter input capability (dry contact or hall effect)
• Alarm powered & dry contact relays
• Optional 4-20mA input (9500 only) and output capability
• Alarm LED, relay or optional callback status
• Eight line backlit display
• Convenient keypad menu access, display contrast adjustment and HOA access control.
• Self charging capacitor to maintain time and history for up to two weeks in the event of a power loss to controller
• EEPROM protection of operating parameters during extended power outages
• Relay, drum level alarm, general alarm, flow alarm and power status LED's
• DIN connections for conductivity sensor and I/O
• Prewired incoming power and relay output connections on specified models (receptacle cords)
• Modular flow assembly with flow switch, quick release sensors and sample port mounted on the polyethylene panel
• Optional remote communications capability via direct serial line or modem connection
