A radio transceiver can transmit analog voltage signals (maximum ±2V) output from sensor/amplifier, such as magnetic detectors, to recorders, such as pen recorders and data loggers, by using radio in a frequency band of 429 MHz.
A driving power source is provided by a DC12V battery or four AA dry cells for a transmitter, and by a DC12V battery or an AC adapter (DC9V) for a receiver respectively.
※ A radio transceiver comes with a dry-cell box and an AC adaptor.

Option
Reception error notification function
Software functions can be applied to all specifications for REC-1650 analog radio receivers.
If radio waves from a TRM-1650 transmitter used over the same channel are broken off, the LED lamp of a receiver (blue) blinks at a high speed to inform a user of a reception error.
