Overview

The ALS300PA23F Limit Switch Box (Valve Position Transmitter Monitor) is a rotary position indication device. Armed with inductive sensors and position transmitter, this device can sense mechanical position (on/off) as well as the position change (0°~90°) of valve and output 4~20mA for remote PLC or PC indication. The visual indicator on the top of the device can also clearly display the valve position for local detection.
