RMU2-S: Full Features List

Simple and very quick to install (typically under 1 hour)
High reliability, long operational life design
Low capital equipment cost
Economical fixed rate operational communication costs
Satellite operation for maximum service coverage
Four galvanically isolated analog input channels
Each analog channel is bi-polar and installer configurable 150mV (50 and 100mV current shunts), 20V, 165V, and 4-20mA measurement ranges
Each analog channel can be configured to read DC or True RMS AC (i.e. induced AC measurements)
DC analog channels include >65dB of 50/60Hz AC rejection
All analog channels are high impedance and allow direct connection to reference half-cells
All analog channels are factory calibrated for simple "connect and go" operation
Programmable low and high alarm window capability on each analog channel with report by exception facilities
Scheduled reporting of data based on customer selected plan (every 6 hours, daily, every 2 days, or weekly readings)
Each channel has independent very high voltage lightning protection (will survive 20kV 10ms surge)
No connection to ground for maximum lightning immunity
Internal temperature measurement and reporting
Powered exclusively from an internal battery for maximum lightning isolation and simplicity
Primary battery will last for more than seven years based on readings every 2 days with a transmission every 8 days
Primary battery is integral to the device but is user replaceable and readily available
Compact two piece mechanical design
Termination block assembly is 100mm x 38mm x 38mm (4.0" x 1.5" x 1.5") and environmentally sealed (mounts in rectifier)
Satellite transmitter assembly is 97mm x 97mm x 52mm (3.8" x 3.8" x 2.0") and mounts externally with a view of the sky
Components connect together wit a single polyurethane cable with small (0.5" diameter) molded waterproof connectors
Transmitter includes a bottom side ½" threaded receptacle that mates directly to electrical conduit fittings
Easy configuration through a USB PC interface
Rectifier GPS position information transmitted to corView host
IP67 sealed enclosure and cabling for harsh environments
Operation in -40°C to +70°C (-40 to 158°F) temperatures
Integral AC line voltage inductive coupling sensor for safe and lightning immune detection of primary line voltage
Magnetic door switch / tamper sensor with exception report
