SLC-220 Smart Leakwise Controller is a digital signal processor that interfaces with Leakwise ID-220 series sensors and gives hydrocarbons spill/leak alerts, including layer buildup and thickness. Alerts are done via a wide variety of outputs and communication interfaces for local or remote reporting.
The SLC-220’s modular design and flexible configuration provide solutions for all specific customer needs. It can be AC or DC line, battery-powered and can operate in wired and/or wireless applications. SLC-220 supports up to four Leakwise `sensors per unit.
When a cellular modem is installed, the SLC-220 can report to multiple remote locations by sending text messages to six cell phone recipients, and/or to an
SLR-220/GSM Receiver. The SLR-220 receives and processes data from multiple remote SLC-220 Controllers and reports to the central control room SCADA via Modbus or dry contacts or 4-20mA output. The receiver verifies timely reporting from all the remote sensors. The information normally received includes sensor name, status, sensor signal value, and battery voltage (where relevant).
SLC-220 comes in two basic configurations, and optional enhancements are available.
SLC-220/N4/LI/RL-420/COM/BASIC includes:
The SLC-220 is designed for low-power consumption in many applications. Each monitored sensor is powered on for a short duration for sampling decision making and then turned off.
All SLC-220 settings and calibration parameters can be changed locally or remotely through:
