Connects up to 10 Modbus sensors in a daisy-chain network or a single 4-20 mA sensor to Tank Cloud.
RST-5003 series Web Enabled Modbus Network Controllers connect APG Tank Cloud sensors to the cloud, as well as any 4-20mA sensor. You'll need this connection module unless you're using an LOE as your Tank Cloud master.
Inexpensive Communications
Unlike competing methods for remote monitoring, the RST-5003 simply connects to a pre-existing Internet connection via an Ethernet cable - be it landline, radio, cellular, or satellite.
Extremely Easy Set-Up
Simply connect the RST-5003 web enabled control module to any Tank Cloud daisy-chain network, or any 4-20mA sensor, via the input terminal and plug in an Ethernet cable. The module will send sensor data through the Ethernet cable to a local area network or the Internet.
Local and Remote Alarming
In addition to the alarming options with our online data portal, the RST-5003 control module has up to two isolated solid-state relays for local alarms and control.
