Light-signal systems receivers: WZ LSA 2-3/G WZ LSA 2-3/P WZ LSA 4-3/G WZ LSA 70-3/G WZ LSA 70-3/P
Receiver WZ LSA 2-3/G
Light-signal system receiver with synthesizer for the 2m band in IP65 housing
For the radio control of light-signal systems, we offer the receiver WZ LSA 2-3/G in the 2 m band (frequency used by public transport).
The receiver is equipped with a frequency synthesizer. One of the pre-programmed frequencies can be set on site using the DIP switch or the RS232 interface. No crystal change necessary. If more frequencies are required, they can be changed in a parameter file.
Additionally, we offer an analog field strength output in this version.
Benefits
- Quick detection of the ideal position
