Hartcran House, 231 Kenton Lane, Harrow, Middlesex, HA3 8RP, England Tel: +44 (0) 20 8909 9595, Fax: +44 (0) 20 8909 2233, www.radiometrix.com Issue 1, 01 August 2012 RX1L Low current Narrow Band VHF receiver The RX1L receiver modules have very low current consumption (1mA) and it offers a reliable data link in an industry-standard pin out and footprint. This makes the RX1L ideally suited to those low power applications where existing narrow band modules are not suitable for prolonged battery powered application. Two versions on the 151.300MHz and 173.225MHz frequencies are available. RX1L is compatible with the Radiometrix TX1 and BiM1T transmitters. Figure 1: RX1L-173.225-5 receiver Features Conforms to EN 300 220-3 and EN 301 489-3 Data rates up to 5 kbps for standard module Fully screened. Very low current consumption Long battery life Applications Solar powered remote installation Data loggers Industrial telemetry and telecommand In-building environmental monitoring and control High-end security and fire alarms Vehicle data up/download Technical Summary Size: 59 x 38 x 7mm Operating frequency: 151.300 or 173.225MHz Supply range: 3.1V - 9V Current consumption: 1mA Data bit rate: 5kbps max.
