Space to Earth laser comms needs special tuning

ESA is looking into using lasers to send large amounts of data from geostationary orbit to Earth. It operates the European Data Relay System (EDRS) packages from that high altitude – payloads sharing room on commercial satellites  – which communicate with a constellation of low earth orbit planet-monitoring satellites called Sentinels. Currently Sentinal-EDRS communication is ...

Photo relays trigger at 2mA

Toshiba has launched two normally open 1-form-A photo-relays that do not need more than 2mA through the input to operate. The input current “reduces energy consumption by approximately 33% when compared to existing Toshiba products such as the TLP240x series”, according to the company. There are two parts: TLP223GA 400Vmax 120mA 17Ω output turn-on 1ms ...
