The SignalFire Wireless Telemetry Ranger Transmitter utilizes LTE-M/NB-IoT technology to transmit sensor data over cellular networks. The Ranger uses the MQTT/Sparkplug protocol to send data directly to the SignalFire Cloud for a complete monitoring and alarming service or can easily be integrated into the customer’s existing system.
The built-in Ranger I/O consists of two (2) digital inputs, one (1) analog input and one (1) relay output.
The digital inputs can detect on/off status or frequencies up to 2kHz for pulse counting and totalizing applications.
The analog input supports a 1-5Vdc or 4-20mA device and provides power to the sensor from the built-in battery pack.
The relay output is a latching single pole single to provide on/off control to a local device.
In addition to the built-in I/O, the Ranger supports an optional expansion modules to support additional sensor types including Modbus, HART, SDI-12, and additional analog and digital inputs.
The Ranger comes complete with the mobile device ready SignalFire cloud interface to monitor, trend and receive alarms either by text or email message. In addition, the cloud platform provides for remote configuration and troubleshooting of the Ranger node and its attached sensor(s) and the relay output may be controlled from the cloud interface to remotely control pumps, motors, and valves.
