The AquaMetrix AM-2250 Multi-Input Controller is designed to be flexible, easy-to-use and easy-to-see. Four measuring parameters are available on the easy-to-use LCD menu inside the front cover. Choose from Conductivity, pH, ORP or Flow. The AM-2250 provides control of external devices using its three independent control and alarm relays. Each relay has adjustable high, low and in range set-points, cycle timer, with adjustable on and off times. This feature enables tighter control of batch processes by eliminating chemical overshoot. Third relay can be activated by temperature or flow totalizer reading as well.
The AM-2250 provides two isolated, independent and scalable 4-20 mA outputs. One 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. The AM-2250TX contains one 4-20 mA output plus the option of PID control. The AM-2250 features a backlit LCD display that can be seen from a distance. The AM-2250TX has the same large display without the backlight feature. The keypad allows easy entry of menu items and numeric values.
The AM-2250 has a rugged NEMA 4X polycarbonate enclosure making it ideal for indoor and outdoor heavy-duty applications. A mounting kit is included for surface and panel mounting. The AM-2250 comes complete, no extra costs are associated with buying boards for different sensors, or buying components to achieve NEMA 4X. All calibration data is stored.
