Product Description
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:
- 2 digital inputs: detect on/off status or frequencies up to 2kHz for pulse counting and totalizing applications
- 1 analog input: supports 1-5Vdc or 4-20mA device and provides power to the sensor from the built-in battery pack
- 1 latching relay output: for on/off control to a local device
In addition to the built-in I/O, the Ranger supports 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. The cloud platform provides for remote configuration and troubleshooting of the Ranger node and its attached sensor(s). The relay output may be controlled from the cloud interface to remotely control pumps, motors, and valves.
The unit is powered by a 4 D-cell lithium battery pack that is field replaceable, with optional solar power or 10-30VDC input. Built-in GPS provides location reporting. Class I Division 2 certified for hazardous locations.
