PS-220 Analog Controller
Documentation
Specifications
Overview
PS-220 Analog Leakwise Controller is a power supply and signal processor that interfaces with a single Leakwise ID-220 Series Sensor to report hydrocarbons spill/leak alerts, including layer buildup and thickness, to users via outputs for local or remote reporting. PS-220 has well-proven reliability and is cost-effective for a basic monitoring system. It can be AC or DC line powered.
