The AV38 Local Monitor and Controller connects to any DataStick System to display sensor and temperature data, and control calibration, configuration and diagnostics. It has two 4 to 20 mA current outputs, two form C relays for alarm, control and wash, and a PID controller for use with pH and conductivity. The convenient DIN enclosure has an ingress rating of NEMA 4X.
The unit has 7 conduit knockouts for easy cabling. The high contrast, backlit display is a 2 line by 16 character LCD. The straightforward keypad consists of 4 directional arrows and MENU, ESCAPE and ENTER keys. Ambient operating temperature range is -20 to 65°C and maximum relative humidity is 95% (non-condensing).
