How the system works
The Gemini receiver has 2 safety relays with forced contacts. As long as the Indus transmitter is active and within the range of the Gemini receiver these relays are enabled. When the emergency stop button on the Indus transmitter is pressed, the relay in the Gemini receiver switches off and the specific application is stopped immediately.
Redundant safety relays, out of range protection & error detection
The status of the safety relays in the Gemini receiver is monitored continuously. If a fault occurs – for example, a relay does not switch or becomes stuck in the Gemini receiver – the 2nd redundant relay will shut down. This guarantees safe operation. Also when the Indus transmitter is out of the range of the receiver, the relays in the Gemini immediately shut down to prevent dangerous situations occurring.
Easy to connect
The Gemini receiver is easy to connect in series to the existing emergency stop circuit of the safety-PLC. The SMA antenna of the Gemini can always be positioned optimally with an extension cable, making it possible to achieve a very large range up to a maximum of 600m also in difficult surroundings. This is ideal for situations where environmental factors that can suppress, absorb or reflect the radiographic signals, such as buildings with a lot of steel, concrete and glass.
The Tyro Gemini receiver is mounted in a robust, splash-proof housing (IP 66) and is available in 2 versions; the Gemini 12/24 Vdc 230 Vac and Gemini (supply voltage).
