AM-2252 Controller
The 2252 series is the latest addition to the AquaMetrix controller line. This new dual channel controller will monitor and control up to 2 parameters simultaneously. pH, ORP, Conductivity, and flow are supported and we added two new input options; ISE and 4-20mA support.
Two Input with two channels the AM-2252 offers inputs on both channels for pH, ORP, conductivity, and ISE, with flow available on channel one. Channel two can also accept a 4-20mA input which can work with any sensor outputting a 4-20mA signal such as ODO2, Turbidity and Chlorine sensors.
Six Parameters Select the parameter you wish to measure from the easy-to-use LCD menu on the inside front cover. Choose Conductivity, pH, ORP, Flow, ISE or a 4-20 mA input. The user interface was designed under the principle that the user should not need to read the manual.
Five Relays The 2252 provides control of external devices using its three independent control relays. The Fifth relay is provided to act as an alarm relay or a Fifth process control relay. Each relay has both adjustable high and low on set-points and can be set for either a rising or falling process. Each relay has its own cycle timer, with adjustable on and off times. This feature enables tighter control of batch processes by eliminating chemical overshoot.
Three Analog Outputs The 2252 provides three isolated, independent and scalable 4-20 mA outputs. Each 4-20 mA output can be configured for PID control. Most users will only use proportional control but the integral and derivative terms are there for advanced control. Each 4-20 mA can be configured for process or temperature.
Zero Cards The 2252 comes complete. There are no extra costs associated with buying boards for different sensors, or buying components to achieve NEMA 4X.
Enclosure The 2252 is packaged in a rugged NEMA 4X polycarbonate enclosure making it ideally suited for indoor and outdoor heavy-duty applications. A mounting kit is included for surface and panel mounting. The enclosure outline makes panel-mount cutouts simple.
One Bright Display A backlit LCD display can be seen from a distance. The keypad allows easy entry of menu items and numeric values.
Calibration No other controller offers the same combination of flexibility and ease for calibration. The process value is visible during calibration so the user knows when it has settled down. Calibration of pH can be with 1, 2 or 3 points. Calibration of conductivity can take as many as 16 points so acids and bases can be measured through their conductivity. All Calibration data can be recalled.
