Product Name
Limit Switch Box, Valve Monitor
Model No.
ALS300AS2
Overview
AS-i Limit Switch Box (Valve Monitor) is a rotary position indication device which can directly comunicated with AS-i master. Armed with ACHEM I/O+Sensor Module, the device can sensor the valve position (On/Off), communicate with ASI master and output voltage (24VDC-1.5W) to operate the solenoid valves or relays based on the command from Master and PC.
