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.
