VELA
RADIO-TRANSMITTER AND RECEIVER
433.92MHz ASK-
Rolling Code
DESCRIPTION:
Vela is an ergonomic and versatile radio-transmitter. It is provided with 4 push-buttons and one LED that goes on during code transmission.
Superheterodyne receiver with ASK modulation, 4 channels with 2 relays and 2 open collector output, high performances and reliability. It has decode
function, auto-acquiring of transmitter, anti-aliasing digital filter for optimized radio-performances. The dedicated firmware is extremely flexible and
intuitive. It grants advanced functions as change of working modality for each channel.
It has a SAW filter for optimizing the selectivity and suppress out of bandwidth noise. It is even equipped with a reliable power supply with anti-noise
filters and line protection against overvoltage.
FEATURES
European I-ETS 300 220 and ETS 300 683 Approved
APPLICATIONS:
Radio transmitter for sirens, burglar alarms, remote light switching, gates, up-and-over doors etc.
