PULSAtrol DCS 900 Series open-air cooling tower & closed loop systems controllers.The DCS 900 controller is designed to control conductivity and feed inhibitor in open-air cooling towers and closed loop systems. It measures the conductivity of the recirculating water and activates a 'bleed' relay output (typically attached to a solenoid activated blow down valve) when it exceeds a set point value. A second relay (typically attached to a chemical metering pump) is activated to feed inhibitor into the tower.
Key Features:
4-electrode conductivity sensor enhances the accuracy and stability of the conductivity measurement.
DIN Connections for input connections of sensor and water meter.
Easy to Program User Interface with the universally recognized symbol key identifying the function you wish to adjust.
All systems include a flow switch that protects your system from feeding chemicals in the event of a loss of flow.
Model DCS 901 - Timer version. The inhibitor relay is activated by the user configurable selectable timer (limit, percent, or percent post bleed). The timer provides protection from overfeed by limiting the time that the inhibitor feed relay will remain active.
Model DCS 902 - Water Meter version. In addition to the selectable timer feature, the inhibitor relay can also be activated by pulse input generated from a water meter. Water meter input can be user configured for standard dry contact or hall effect.
